Types of roll insulation and the distinctive features of each of them. Insulation in rolls, how to use it correctly and where? Roll insulation for outdoor use

Hello, dear friends! When choosing thermal insulation materials for a residential building and outbuildings, you probably paid attention to roll insulation.

It is easy to use, its small thickness does not “steal” space, and the price in most cases is quite reasonable. Where and how can roll thermal insulation be used? What properties, advantages, disadvantages does it have? We'll tell you in this article.

Roll insulation refers to thermal insulation materials produced in rolls, based on expanded polystyrene foam or polyethylene. Now manufacturers are mastering the production of foam roll materials based on environmentally friendly natural raw materials, for example, rubber, balsa wood, cellulose.

Rolled heat insulators based on polymer materials are divided into two types:

Insulation in rolls with foil has high heat-retaining properties. The peculiarity of this type of insulation is that the layer of cellular polyethylene is covered with a layer of foil 0.5–2.0 mm. This material is resistant to high temperatures up to +180 C.
Conventional fine-porous insulation, produced in the form of rolls of various sizes. In this case, there is no foil reflective layer.

There are also roll insulation materials for mineral based– these are mineral wool and basalt wool in rolls. In terms of properties and characteristics, these insulation materials are absolutely identical to ordinary mineral wool.

Thermal insulators in rolls based on foamed polymers have the following properties:

high level of environmental safety;
durability, not susceptible to rotting, exposure to rodents and insects;
excellent heat-retaining properties with small thickness;
low level of moisture absorption;
good sound insulation;
easy to install, can be cut into any parts and shapes without any problems.

Most thermal insulation in rolls have a self-adhesive base, which allows you to further simplify the insulation process and save on purchases adhesive composition.

Scope of application of roll insulation

Roll insulation materials are used for thermal insulation of vertical and horizontal surfaces. Foil material is indispensable for creating thermal insulation in bath rooms, as it retains heat well and has heat-reflecting properties. This material has also found wide application for thermal insulation of individual structures, joints, and in hard-to-reach places.

Let's look at the main ways to use rolled heat insulators.

Rolled thermal insulation for walls

Roll insulation for walls it can be used as a heat-insulating material applied under decorative finishing, including wallpaper.

The application technology is very simple:

self-adhesive material is glued to a wall that has been prepared in advance, leveled and cleared of debris and old finishes;
A cement-based adhesive is applied to the heat insulator layer, its properties reminiscent of liquid plaster;
After the adhesive has hardened, you can begin gluing the wallpaper.

The use of such material for wallpaper will significantly increase the heat-retaining properties of the walls, as well as their sound insulation.

Rolled floor insulation

Used as a substrate for various types of decorative coatings floor. It not only has heat-insulating properties, but also gives the floor “softness”, eliminates squeaks and sounds when the floor covering shrinks and moves.

In some cases, a foil thermal insulator can be used to insulate the floor; this will increase heat retention; however, the cost of materials reinforced with foil is 30–60% more expensive.

The technology for performing floor insulation work using foamed polymer in rolls is very simple:

the material is glued to a wooden floor or concrete screed using an adhesive composition or self-adhesive properties;
leveled so that there are no “bubbles”;
The floor covering is laid on top.

The advantages of such a heat insulator include ease of installation, lack of debris, durability and environmental safety. When choosing a roll insulation for the floor, it is worth remembering that the “softer” the floor covering, the denser the insulation should be.

In other words, it is better to use a polymer with maximum density under linoleum, otherwise when you walk you will “sink” into the floor covering, but under laminate or parquet you can lay a polymer with any density.

Rolled roof insulation

Suitable for thermal insulation of pitched and flat roofs. A roof insulated with such material will remain warm for several decades. You can install thermal insulation on your own, without involving highly paid specialists. The heat insulator is located between the elements of the roof rafter system, and distortions, the formation of waves and other defects are not allowed.

In some cases, for example, when insulating residential attic room or in regions with cold climates, it is recommended to lay insulating polymer in two layers.

The technology for installing roof insulation depends on design features. The best option is when thermal insulation is calculated at the design stage. In this case, the work comes down to rolling out the rolled material and gluing it onto inner surface roof, a layer of vapor barrier material is laid on top and the final finishing is installed, for example, siding, lining, etc.

Conclusion

Rolled polymer heat insulation is an excellent option for increasing heat retention indoors. It is easy to use, flexible, durable, and not expensive. Foil material is indispensable when insulating a bath or sauna, as it has reflective properties and is moisture resistant.

How do you look at the prospect of reducing home heating costs by almost a third? We think this is a case where comments are unnecessary. It is possible to achieve such a result; you just need to choose the right thermal insulation for the roof.

One of the most common thermal insulation materials is mineral wool, in particular in the form of mats. However, when it is necessary to insulate, for example, large areas, such a solution is ineffective. For such cases, roll insulation is more suitable.

All materials of this type have approximately the same advantages, which explains their high demand. We are talking about their qualities such as

low thermal conductivity,
good sound insulation,
optimal hygroscopicity,
high hydro-repellent properties,
chemical resistance,
fire safety.

And this is not the whole list.

Rolled insulation, due to its elasticity and flexibility, easily restores its shape and is suitable for working on uneven surfaces. It has no temperature restrictions, as it retains its performance characteristics at extreme temperatures.

Scope of application of insulation in rolls

It is successfully used for roofs and basements, floors and ceilings, pipes and more. Installing thermal insulation from this material is a fairly simple process. Moreover, the work can be done independently, without the involvement of additional labor. Therefore, this type of thermal insulation has gained great popularity in private construction, in particular, bathhouses, outbuildings, etc.

Types of insulation

A separate group includes materials that have a protective layer of foil. They are somewhat more expensive than others, but have many additional valuable properties.

Foil itself does not have the thermal conductivity necessary for insulation, however, it effectively retains heat due to the ability of the reflective surface to block infrared rays from the room. It is worth noting that at the same time it does not allow their penetration from the outside. The latter is a rather useful quality for roofing insulation, especially in hot summers, when the roof is exposed to sun rays gets very hot.

Rolled foil insulation allows you to provide maximum length material, that is, it is laid from one whole strip, which is extremely important for its effectiveness. . These include foam rubber, polyethylene and other materials in roll form

These materials do not hold their shape and are easily rolled up. They are quite effective and easy to work with. Unlike foil thermal insulation, they are used in combination with a vapor barrier, which creates an ideal tandem against the cold.

These include foam rubber, polyethylene and other materials in roll form. These materials do not hold their shape and are easily rolled up. They are quite effective and easy to work with. Unlike foil thermal insulation, they are used in combination with a vapor barrier, which creates an ideal tandem against the cold.

This is the most common type of insulation. This form of packaging is considered by many to be optimal, since with this approach long strips of insulator occupy a small volume. Most often, floor beams or mounting profiles are installed in increments equal to the width of the roll. This greatly simplifies installation: firstly, the material is simply spread over the surface and secured, and secondly, no unnecessary seams are formed.

Multilayer foil material comes in several types. Type A provides for the presence of one foil layer. Type B has self-extinguishing polyethylene between layers of high-quality aluminum foil. Type C comes with special adhesive base, which greatly simplifies its installation. Type A has the lowest cost and the least rigidity.

The foil thickness of Penofol is 12 - 30 microns with a base thickness of 2 - 10 mm. To insulate surfaces operating in fairly harsh conditions, material up to 40 mm thick can be used.

Eco-friendly, safe, suitable for insulating children's rooms.

Scope of application of roll insulation

Let's look at the main ways to use rolled heat insulators.

Rolled thermal insulation for walls

Rolled wall insulation can be used as a heat-insulating material applied under decorative finishing, including wallpaper.

The application technology is very simple:

self-adhesive material is glued to a wall that has been prepared in advance, leveled and cleared of debris and old finishes;
A cement-based adhesive is applied to the heat insulator layer, its properties reminiscent of liquid plaster;
After the adhesive has hardened, you can begin gluing the wallpaper.

The use of such material for wallpaper will significantly increase the heat-retaining properties of the walls, as well as their sound insulation.

Rolled floor insulation

It is used as a substrate for various types of decorative floor coverings. It not only has heat-insulating properties, but also gives the floor “softness”, eliminates squeaks and sounds when the floor covering shrinks and moves.

In some cases, a foil thermal insulator can be used to insulate the floor; this will increase heat retention; however, the cost of materials reinforced with foil is 30–60% more expensive.

The technology for performing floor insulation work using foamed polymer in rolls is very simple:

the material is glued to a wooden floor or concrete screed using an adhesive composition or self-adhesive properties;
leveled so that there are no “bubbles”;
The floor covering is laid on top.

Rolled roof insulation

In some cases, for example, when insulating a residential attic space or in regions with a cold climate, it is recommended to lay the insulating polymer in two layers.

The technology for installing roof thermal insulation depends on the design features. The best option is when thermal insulation is calculated at the design stage. In this case, the work boils down to rolling out the rolled material and gluing it to the inner surface of the roof, laying a layer of vapor barrier material on top and installing the final finish, for example, siding, lining, etc.

Application of roll insulation

This technology is far from perfect and creates only an illusion real savings material resources, since in fact this type of insulation is inferior in all respects to such sprayed analogues as polyurea

Another difficulty is the application technology. It should be mentioned right away that all surfaces must be prepared: thoroughly cleaned or even washed. Even minor pollution can lead to negative consequences. Self-adhesive insulation is applied similar to adhesive tape, but this method is less effective. Over time, the glue loses its properties, especially under the influence of temperature changes, and the material peels off. Fused insulation is applied using a gas torch. This is a slow and painstaking process, but the grip is somewhat better, although there is no guarantee that it will not give way in some places.

Regardless of whether roll waterproofing of the floor or any other surfaces will be carried out, this process takes a lot of time and effort. Accordingly, the deadline for putting the facility into operation is being delayed. And this work is not cheap. Therefore, this technology is far from perfect and creates only the illusion of real savings in material resources, since in fact this type of insulation is inferior in all respects to such sprayed analogues as polyurea.

Advantages and disadvantages

The main advantages of rolled material are:

Versatility. Suitable for thermal insulation of any surfaces. For complex spatial shapes, including curved ones, you can cut out a suitable piece.
Minimum requirements for surface preparation before installation.
Benefits in terms of material price and work productivity when insulating large areas of walls, especially straight sections.

Roll materials have disadvantages.

High labor intensity when laying in frequent lathing; additional time is required for cutting.
Low rigidity does not allow them to be used where it is necessary to withstand significant loads.

In general, the advantages compensate for the disadvantages, which explains the high popularity of roll materials among consumers.

The materials are harmless to health provided they are used correctly and fire safety regulations are observed.

Types of roll insulation

Mineral wool

Available in several modifications. A common disadvantage is hygroscopicity. All insulation materials must be protected from direct contact with liquids; the difference between them is only in the intensity of its absorption.

Glass wool. Pros: one of the cheapest (made from broken glass that has been melted down), unattractive to rodents and insects (often used when installing heated floors). Increased density, the ability to dampen sounds, and resistance to combustion add advantages to glass wool in use. The downside is the complexity of working with the material. When installing glass wool-based roll insulation, you cannot do without protective equipment. And not only the respiratory and visual organs; you need thick, closed clothing - microscopic fractions of glass penetrate literally everywhere.
Slag-like. It is also based on waste, but from the metallurgical industry. In terms of cost, this insulation is comparable to glass wool (even somewhat cheaper), but in terms of resistance to high temperatures it is inferior. But in terms of thermal conductivity it is the leader among mineral wools. In all other characteristics, it is approximately on the same level as other insulation materials of this group. Cons: absorbs moisture (increased hygroscopicity), does not dampen noise well.

There is also a drawback that makes the use of slag wool for insulation of metal pipes impractical. It is not recommended to be used for thermal insulation due to residual acidity - it has a destructive effect on steel.

Basalt wool. The raw materials are processed rocks. Pros: ability to withstand high temperatures (up to +700), optimal combination thermal conductivity/density characteristics. The peculiarity of the material is that after getting wet it does not lose its thermal insulation properties (although there is a limit on the percentage of humidity), it is characterized by high sound absorption, fire-resistant, and “eco-friendly” (safe for allergy sufferers).

There are few disadvantages: this insulation requires high-quality vapor barrier, cakes over time.

Any of the listed thermal insulation materials is also sold in a “foil” modification. The thinnest layer of aluminum increases the heat-reflecting properties of the product and protects it from contact with moisture.

Polymers

All roll insulators are made on the basis of foamed polyethylene or polypropylene. They differ in characteristics, but given the small thickness of the canvases, the difference in thermal conductivity between them is not particularly significant, so they can be considered identical. The most advertised, although not the only representatives of this group of elastic insulation materials on the market: Penofol (PE) and Penotherm (PP).

Russian products under the brands Energoflex, Energofloor, Jermaflex (combined material) from ROLS ISOMARKET have good reviews. It is relatively new on the market, but judging by the exchange of opinions on the Internet, it has proven itself to be effective and universal insulation. Its quality was also appreciated by specialists.

The main role is given to the metallized layer. It is the foil that prevents heat rays from passing through the material. The heat insulator is covered with it on one or both sides; The choice of option is determined by the application conditions.

When choosing insulation of an unknown brand, you may encounter a substitution of concepts. To reduce costs, some manufacturers apply metallized spraying to the thermal insulation instead of a layer of foil. Such a screen is not durable, and is significantly inferior in efficiency to an aluminum coating.

So which option is better to choose cotton wool or polyethylene foam?

The main point that is important to understand is that foamed polyethylene or polypropylene in the form of rolls is precisely thermal insulation, that is, a material whose purpose is to slightly improve the characteristics of walls, and not to fully insulate them. Regardless of where it will be fixed - from the inside or from the front part

But basalt wool is already a real insulating layer. True, if used indoors, the wall will still freeze, but noticeably less heat will escape from the room.

It turns out that foam propylene from the inside will give less effect than cotton wool, since the temperature will only rise by a degree and a half. And even if you carry out external installation, the “picture” will be the same, but with only one positive aspect - the wall will freeze a little less and condensation from the room will disappear.

At the same time, the material has an undeniable advantage - it is cheap and very easy to install. It is more difficult and expensive to work with cotton wool because you will need to make a false wall (usually drywall) to protect the basalt fibers, and in addition, it is important to take care that moisture does not get into the structure of the material. If this happens, then the effect of all the work done will be zero, since all the thermal insulation qualities will very quickly disappear.

Here it seems that cotton wool is better anyway (because it’s “warmer”), but everything is decided by the nuances of the situation. Yes, cotton wool seems to be good, but what is the point in it if, for example, you need to insulate a shower room not in the house, but, for example, in the country and you don’t want to invest? Obvious budget solution in this case, it is a metallized insulator - stick it on the wall and forget it.

But in the case of a more or less capital approach, but again in the absence of significant financial resources, it is better to opt for mineral wool and insulation from the inside. It turns out that there is no ideal option and you need to make a decision only based on the characteristics of the project.

Characteristics

Thermal insulation material in rolls, produced under various brands, is characterized by general characteristics.

Environmental friendliness

The insulation meets regulatory environmental safety requirements.

As a rule, it contains salt heavy metals, alkalis, acids, oxides, phenols or toxic organic compounds that are inactive at room temperature are present in minimal quantities.

Due to its low chemical activity, thermal insulation practically does not interact with aggressive environments, and therefore, for example, is not afraid of exposure to solvents.

Biological resistance and fire safety

The material has a high level of biological resistance. As a result, there are no rodents, fungus, or mold in it. It is of no interest to insects and animals as food. Depending on the composition and other characteristics, the insulation can withstand high temperatures.

Air and vapor permeability

If insulation is used to insulate floors or walls, air permeability is an important indicator.

When using rolled materials, you do not have to worry about excessive dampness in the room, condensation and other negative phenomena, provided that the installation is done correctly.

When going shopping, it is worth remembering the following aspects of your choice:

Suitable for indoor and outdoor use various variations insulation.
The surface that will be covered with roll insulation also matters. There is a fundamental difference between the materials used to insulate the ceiling and walls. Each of these bases has its own insulation.
It is also important to remember what material the walls are made of. Thermal insulator for wooden base may not be suitable for concrete base and vice versa.
When choosing the thickness of the material, it is worth taking into account the temperature conditions in winter period and climate features for a particular region.
Before purchasing, you should definitely familiarize yourself with the quality certificates and other permitting documentation for the selected roll insulation, and in addition, make sure that the packaging is intact. Moisture, even in small quantities, can negatively affect the calculated parameters of the material and its properties.

Choose high-quality material from trusted manufacturers

Insulation in rolls is available on the market in a wide range. Each of them has its own characteristics, positive and negative characteristics. The choice of a specific option is up to the user, but if there are difficulties, you should not rely on chance. It is better to seek help from professionals and save your nerves and money.

3 Rolled foil thermal insulation

Rolled foil insulation on the market is usually made either from polyethylene foam (the fairly popular brand Penofol) or from polypropylene (Penotherm).

These are two almost identical materials, the difference between which lies only in physical and mechanical characteristics. If we consider only those that affect the direct effectiveness of use as a thermal insulation material, then foil roll insulation for walls based on polypropylene appears more preferable.

Thus, the polypropylene base has an order of magnitude lower thermal conductivity (a difference of about 30%), less moisture absorption and better resistance to external mechanical influences.

In fact, the last factor can be neglected, since foil insulation materials themselves, due to their minimal thickness, do not perform effective insulation when the foil is damaged, so it is important to look at the quality of the foil coating. .

Rolled penofol with one-sided foil

Unscrupulous manufacturers, in order to reduce the cost of products, may not use aluminum foil as a shielding layer, as required by technology, but ordinary metal spraying.

The efficiency of such spraying is much lower than that of foil, but the cost of such products, sold under the guise of high-quality insulation, is comparable to high-quality products from trusted manufacturers. When choosing foil-covered insulation for walls, floors, or pipes, carefully check the quality of the shielding layer.

High-quality foil thermal insulation has the following advantages:

High heat shielding coefficient, about 97%;
Wide functionality - foil materials are used not only for household insulation of walls, floors and ceilings, they are also widely in demand for thermal insulation of all kinds industrial equipment;
Minimum roll weight;
Easy to install - foil thermal insulation does not require frames, anchoring and similar frills; it sits on the wall using polyurethane foam or regular construction adhesive;
Minimum cost - the price of foil materials is significantly lower than that of mineral wool;
Complete vapor barrier;
Safety for the human body.

Foil thermal insulation has only one significant disadvantage– it is subject to combustion. Temperature operation of polypropylene - 150 degrees, polyethylene foam - 80 degrees.

Characteristics

Rolled insulation materials are characterized by the following main parameters:

Environmentally friendly. All models on the market must comply with safety requirements for installation, operation and disposal. They must contain small quantities harmful substances, these substances should not be released from the insulation during its storage, installation and during use. The packaging indicates the disposal method. The materials are resistant to organic solvents and other active substances.
Fire and bioprotection. Mineral insulation does not burn on its own and prevents the spread of flame. Foam materials can withstand fire for a certain time. The materials prevent the formation of mold and repel rodents.

Air and vapor permeability. Key characteristics. They show how much air or water vapor at a certain temperature can leak through a unit area of material. Vapor permeability is necessary in order to remove excess moisture from the room to the outside through the walls and their ventilation systems.
Strength. An important characteristic of insulation under wallpaper. Touching, including with hard objects, should not damage the wallpaper.

Which roll insulation to buy

Roll insulationis the name of a whole class of lightweight thermal insulation, widely used in civil and industrial construction. They are made from staple fiberglass with the addition of various binding materials, fillers, water repellents (substances that repel water), which give them softness, elasticity and resilience. Rolled thermal insulation is the most inexpensive of all types of insulation, and therefore is in consistently high demand among builders.

This section of the site presents roll insulation, their price and parameters of the rolls. All product information from different manufacturers given on one page. Here you will find a brief description of each of them.

ROLL INSULATIONS URSA

This is a very famous line of insulation European manufacturer- concern "URALITA". URSA brand roll insulation materials are soft elastic mats made of staple fiberglass. Each brand has its own marking, which allows customers to easily navigate the characteristics of the material and, accordingly, its purpose. URSA insulation materials are high-quality lightweight insulation materials recommended for use in horizontal unloaded building structures. Good thermal characteristics, ease of transportation and installation make them extremely popular for many years.

A special place in the line of roll insulation products of the URSA Concern is occupied by new generation insulation materials under the URSA PUREONE trademark (in rolls and slabs). Acrylic, a neutral and safe polymer, is used as a binding component. The production technology of these insulation materials excludes the use of phenols and formaldehydes, which makes them particularly environmentally friendly. They are widely used in Europe, America, Japan for heat and sound insulation indoors. In Russia they also gained well-deserved popularity.

KNAUF ROLL INSULATIONS

These are natural mineral wool insulation materials made using innovative ECOSE technology. During the manufacturing process, binders based on natural components are used, so it has a pleasant color of natural flax and a structure that is pleasant to the touch. Due to environmental friendliness, such insulation can be used indoors.

You can always contact our specialists, who will tell you where you can find additional information about the insulation you are interested in or give advice on installing the material.

Installation technology

The technology for installing roll insulation is slightly different from slabs. They begin to insulate the walls or floor initially. The walls are mainly made of slabs, as is the straight ceiling. Therefore, often, floors and pitched ceilings-walls are suitable for insulation and installation. When insulating the floor, it is worth looking at what type of insulation is available.

Insulation in foil is mainly used, but sometimes rolls of insulation are covered with ordinary heat-insulating foil or metal film. The insulation should extend 1 cm away from the walls. This is due to the fact that when temperature changes, the material contracts and expands. The lack of free space in metallized or foil insulation leads to its deformation and damage over time.

Ceiling (pitched) insulation is attached between the rafters, cutting out a little more in order to insert it better between the boards. They are inserted strictly from bottom to top to avoid voids. After installation, the surfaces are clamped with main profiles or boards for application of additional (for example, vapor barrier) materials on top. The work is carried out especially carefully.

Let's move on to installing walls with roll-type insulation from the inside. It is produced by preparing walls for pasting. A special glue for cotton wool is diluted; the wall should not be covered with putty or plaster; only bare concrete or brick is allowed. The composition is applied to the wall evenly using a special comb, after which they begin gluing the rolls, which can be cut for convenience.

In this case, it is advisable to make the wall itself level, flat, if there are no further plans for sewing it into a box or gluing glass wallpaper. After the material is mounted on the wall, you need to screw it on. Each petal should be slightly recessed in the cotton wool. At least 5 fixing holes are required per 1 m2. It is better to fasten the sheets themselves and the space between them (in this case, both sheets will adhere, which will avoid warping and ensure level and plane).

After the sheets have set, a layer of glue should be applied. The technology is similar to puttying, only with a different solution

It is important to monitor the level and plane. It is necessary to make at least two passes, since it will be problematic to lay a good layer the first time

After leveling, regardless of the type of room, you can proceed to the next work. When installing plasterboard sheets inside the house, they are attached using dowels to a layer of thermal insulation, which should preferably be treated with glue, as in the previous paragraph.

About the advantages of URSA roll insulation, see the video below.

Operational imperfections and maintenance difficulties

Each type of waterproofing material has its own unique features. Thus, TechnoNIKOL, which, according to the manufacturer, can withstand heavy mechanical loads, may not withstand increased soil mobility. Therefore, many people use a modification for waterproofing road substrates from the same manufacturer. But these are unjustified costs.

As for maintenance, for example, if the polyurea coating is damaged, it is enough to simply spray a small layer locally on the area. But roll waterproofing that has peeled off in any place requires serious repairs. It is necessary to remove it, at least in this place, prepare the base, reapply insulation, covering the resulting seams. Of course, we are not talking about any aesthetics, and the quality of such a patch will be far from perfect.

Waterproofing with roll materials is not universal. Thus, with their help it is impossible to process surfaces of complex shapes, for example, the underbody of a car. And even roll roof waterproofing can become a serious problem. In addition, high temperatures have a detrimental effect on this material and the degree of its adhesion to the base.

The main disadvantages of waterproofing with roll materials in specific conditions:

Rolled roof waterproofing – impossibility of processing surfaces of complex shapes, long application process, exposure to the negative effects of temperature changes, difficulty of maintenance
Rolled floor waterproofing – poor perception of constant mechanical loads, especially in vibration conditions
Rolled foundation waterproofing – instability to the negative effects of moving soils, additional load on the foundation, which is undesirable in areas with high levels groundwater and in loose soil foundations

Characteristics of basalt wool

If roll insulation for wallpaper, discussed above, is not suitable for you, then you can choose basalt or fiberglass wool, which has a wide application potential. It can be installed on walls or floors, as well as on ceiling spans. It is not recommended to use this material for sloping roofs, this is due to the fact that over time the mass slides and the insulation density is broken. If you want to use this flooring, you need to lay at least two layers. This will allow you to get 1 decimeter of thickness. If there is a need to insulate the walls, then half the amount should be used, and laying the material in one layer will be sufficient. If you want to achieve an effective heat-saving screen, then you should use similar thermal insulation with vapor and waterproofing.

What to consider when working

Insulation with mineral roll materials can be carried out at any time of the year, it is only important to ensure that the material is protected from precipitation. . The use of foam materials mounted on an adhesive layer depends on the air temperature

Usually the limit is down to –10C. Special adhesives are also produced that are effective down to –20C.

The use of foam materials mounted on an adhesive layer depends on the air temperature. Usually the limit is down to –10C. Special adhesives are also produced that are effective down to –20C.

Before insulation begins, minimal surface preparation is required:

Dismantle pipes, electrical wiring, lamps, decorations, plants, etc.
Clean the walls from remnants of old coatings, debris and dust.
Install sheathing for mineral insulation.
Level and clean the surface for gluing foam thermal insulators.

Installation does not require special equipment; the tools you will need are:

construction knife;
stapler;
screwdriver;
hammer;
double sided tape.

It is more convenient to carry out installation and cutting of roll insulation together by two people, especially for large volumes of work. Small volumes can be done by one master.

Insulation process

The sequence of operations when installing mineral insulation is as follows:

A vapor barrier film is attached to the prepared wall.
A sheathing made of wooden blocks or metal profiles. The recommended guide pitch is 50 or 60 cm.
Rolls are cut in accordance with the selected pitch. The cutting must be carried out so that the insulation fits tightly between the guides and, when straightened, provides a better fit to the guide.

Disc dowel

Mineral wool is attached to the wall using disc-shaped plastic dowels, cut according to the thickness of the layer at the rate of 4-5 per square meter.
The windproofing film is attached to the guides on top of the laid cotton wool. The joints of the film are sealed with double-sided tape. Installation of insulation on the walls of the house.
Installation diagram under the sheathing
Thermal insulation is complete. You can proceed to the installation of the selected cladding - wooden or vinyl siding. To ensure ventilation of the façade, a secondary sheathing of thin slats is installed on top of the wind barrier.

Read on the topic -.
Installation of rolled foam insulation for external and interior walls in itself is simpler, but requires better preparation surfaces. It will have to be leveled more carefully - foam will not be able to hide unevenness as much as mineral wool.
It is not recommended to fasten foam rolls using a construction stapler - the staples create so-called thermal bridges through which cold can penetrate into the warm part of the room. The thermal insulation effect of the material is somewhat reduced.
How to fix insulation to the wall:
- Clean and level the wall surface.
- Cut the material for end-to-end installation.
- In places of complex spatial shape - near openings, in corners, junctions of building structures (beams, balconies, etc.) it is better to try on the cut pieces before applying glue or removing the protective layer.
- Apply glue to the heat insulator or remove the protective film from the adhesive layer.
- Glue the material, moving from bottom to top.
- Smooth the surface with your hands or a rule, achieving the best fit. If large air bubbles have formed, they should be carefully pierced in the center with a sharp needle and, moving from the edges of the bubble to the hole, squeeze out the air.
After half an hour, the glue will set and the thermal insulation layer will be ready for use. When installing a cork sheet, glue specially designed for cork is used. It is applied both to the wall and to the cork. Before gluing wallpaper, you should wait until the glue has completely dried to avoid warping.

2 Rolled thermal insulation based on mineral wool

The quality of this category of insulation is regulated in accordance with the requirements of GOST RF “52953-2008”. This quality standard allows the following thermal insulation material to be classified as mineral wool insulation:

Basalt wool is a material produced by melting rocks and then forming microscopic fibers from them, connecting them into a solid carpet;
Slag wool is a material made from waste from the metallurgical industry. As a rule, it costs much less than basalt wool;
Glass wool is a morally obsolete material, but still quite often used due to its low price. Produced by melting cullet.

Rolled basalt wool has a characteristic yellow tint

Rolled insulation based on mineral wool, due to its elasticity and flexibility, is an extremely versatile material that can be successfully used for thermal insulation of walls, floors, attics, and other flat surfaces, as well as for thermal insulation of pipes.

2.1 Mineral wool production

Let's look at the technology for making mineral wool using basalt insulation as an example. Basalt rocks, the chemical composition of which meets GOST requirements, can be melted in two ways - hot and cold.

The hot method involves heating basalt rocks in blast furnaces, the cold method involves exposure to electromagnetic radiation (like a conventional microwave).

The molten rock is fed into a centrifuge, which is equipped with constantly cooling carbide disks. Under pressure, molten basalt is fed into a centrifuge and falls onto rotating disks, where individual basalt fibers are formed from the melt through the process of cutting cooling and pressure drop.

The resulting fibers are immediately removed from the drum by a special functional element and supplied via a conveyor to a laying machine, which forms a carpet of basalt wool of the required thickness.

After laying the carpet, the fibers are impregnated with various impurities, which are necessary to give the final product the required characteristics - hydrophobicity, fire resistance, density and elasticity.

Slag material, as a rule, has a darkish tint

2.2 Advantages and disadvantages

Among all the thermal insulation materials on the market in the middle price category, it is mineral wool that has the lowest thermal conductivity. Although the leaders in general are polystyrene foam and mineral wool.

An important factor is that the thermal insulation properties of mineral wool do not depend in any way on any external conditions - this material does not expand under the influence of moisture and is not exposed to thermal expansion, microorganisms and rodents do not grow in mineral wool.

Rolled mineral wool insulation is produced with a wide variety of performance characteristics - you can choose either low-density mineral wool for insulating pipes and other uneven products, or dense material for thermal insulation of surfaces experiencing external loads– floor or attic floor.

An important advantage of mineral wool is its fire resistance. This material can withstand temperatures up to 700 degrees; it does not ignite even under direct exposure to fire. It is also worth noting good noise-reducing properties - by insulating walls and floors with rolled mineral wool, you will solve not only the issue of insulation, but also sound insulation of the house.

The only drawback of mineral wool is its high vapor conductivity, due to which the installation of a special vapor barrier film is required when installing this insulation.

Thermal insulation of the pipeline using rolled glass wool

Rolled mineral wool insulation can be used for the following purposes:

Insulation of roofs, floors, walls, and any flat surfaces;
Thermal insulation of pipes and pipelines;
Thermal insulation of industrial equipment;
Insulation element inside sandwich panels (here better thermal insulation Hitrock);
Internal insulation in false walls and when laying hollow walls;
External insulation of house walls followed by plastering.

Types and characteristics

Mineral wool insulation materials are widely used.

Their popularity is explained by their high operational and technical indicators and relatively low cost.

Roll insulation based on mineral wool includes:

. The material is obtained by melting rocks of a certain type and forming thin fibers.
Glass wool. Insulation made from molten broken glass is affordable. Thanks to this, the material is in high demand, although it is considered obsolete.
Slag-like. The material is based on waste from the metallurgical industry, so it has a fairly low price.

Insulation based on mineral wool has its own distinctive properties:

temperature resistance;
low thermal conductivity;
high density;
absorption of vibrations and sound vibrations;
no shrinkage after long-term use.

Foil roll insulation is made from expanded polystyrene foam by applying it to a layer of foil. The foil creates the effect of a thermos, pushing heat back into the room.

Expert advice: foil insulation can be used when installing infrared floors and for thermal insulation of wooden saunas and baths.

The main properties of foil roll insulation include:

high thermal insulation;
reliable vapor barrier;
good noise absorption;
fire safety;
durability.

Intercrown roll insulation represents a rather specific solution. The main purpose is to fill the empty space between the crowns. Even high-quality assembly of houses from profiled timber or logs cannot guarantee a tight fit of the elements. An inter-crown heat insulator will fill the free space.

The material is produced in narrow rolls; natural and harmless materials such as linen, batting, and jute are used for its production. The use of this type of insulation is possible both during construction and during operation of the house. Everyone knows that over time, wood dries out, forming gaps between building elements. By filling the resulting voids with insulation using a chisel and mallet, you can retain maximum heat in the house.

Thermal insulators based on mineral wool

Materials of this group are most widespread in the domestic market. This is due not only to their excellent operational and technical data, but also to an acceptable pricing policy - such a combination is so far unattainable for competitive offers.

Flexibility makes work easier

Assortment and features of species

The term “mineral wool” is a unified designation for a whole range of heat insulators, namely:

basalt wool - for the production of this material, the technology of melting certain rocks is used, followed by the formation of the finest fibers on their basis, woven into a single carpet;
glass wool is a material, although it is considered obsolete, but still has a fairly high demand due to its affordable cost. For its production, remelted broken glass is used;
slag wool - it is based on waste obtained in the metallurgical industry. Due to this, such insulation in rolls has a lower cost than basalt and glass wool.

Each type of mineral wool has its own distinctive features and characteristics. Thus, glass wool perfectly resists high temperatures, up to 450 degrees - after exceeding this parameter, the material is destroyed irreversibly. The highest density is 130 kg/m3, thermal conductivity values vary in the range of 0.038–0.046 W/m*C.

Glass wool in rolls

Glass wool is not flammable, it does not even smolder, it perfectly absorbs vibrations, resists sound vibrations and does not shrink even after long-term use. At the same time, the material is not moisture resistant, and getting it wet completely eliminates the entire range of positive characteristics. It is worth noting the fragility of glass wool, as well as the fact that contact with human skin causes severe itching.

As for basalt wool, such rolled thermal insulation can withstand temperatures up to 700 degrees. Its thermal conductivity is 0.035–0.045 W/m*C, and its density reaches 220 kg/m3. The material is resistant to moisture; slight wetting does not affect its parameters at all. Basalt wool is an environmentally friendly and non-irritating material.

Basalt wool

Slag wool has the largest mass, and its density reaches 400 kg/m3. The material is characterized by minimal thermal conductivity - 0.046–0.048 W/m*C, and the highest temperature it can withstand is 300 degrees - its increase causes melting of the slag wool and destruction of its structure.

Slag in rolls

The dimensions of the materials largely depend on the manufacturer, but most often they have the following standard sizes:

length – varies between 3-6 m or more;
width - standard 0.6 and 1.2 m, although individual products brands can have a width of 1.22 m and 0.61 m;
thickness – 50, 100 and 150 mm.

Wall mounting

Despite the fact that roll insulation is created from different materials, mount it on the wall according to the standard principle. All differences will lie in the composition of the glue that will be used, and, accordingly, in the drying time of the substrate on the wall.

Conditions for carrying out installation work with the substrate indoors

To glue insulation to the walls of your apartment, you have to do the following:

First of all, it is worth preparing the surface, for which you need to remove the old wallpaper, plaster the wall, smoothing and sealing large cracks and irregularities. Small defects in the wall surface can be left, they will be closed.
Next, the surface of the wall must be primed. This is done either using glue, which we will use to glue the substrate, diluted in a weaker consistency, or using a special primer composition. After priming, you need to wait until it is absorbed into the wall and dries.
It is recommended to cut the rolled insulation into pieces of the required length in advance so that it can lie down and level out. This will make gluing it up a lot easier for us. When cutting the canvas, add a little material for insurance.
We prepare the adhesive composition according to the instructions on its package. If we are dealing with a substrate with a top layer of paper, then we apply glue to the wall and to the cut pieces, and let them soak in the composition for literally 5 minutes. If the backing is equipped with non-woven edges, then it is enough to smear the wall, and the material will easily attach to it.

Next, we proceed directly to installing the paintings on the walls. This process is reminiscent of wallpapering; the pieces are also glued together and carefully smoothed out. The air is expelled from under the canvas and it sticks firmly to the wall. It is convenient to use a rubber roller; it will create the necessary pressure and will not damage the insulation material.
After the insulation has dried, after about 1-3 days, seal the joints of the panels with regular masking tape. Krepp will allow us to give solidity to our structure.
Now our walls are well insulated, and we can proceed directly to gluing the wallpaper itself.

Wall insulation will allow us to create the most comfortable living conditions. It will serve us for a long time, no matter how long any wallpaper hangs.

The not always convenient and functional thermal insulation boards are being replaced by an improved version of thermal insulation - roll insulation, equally effective for both walls and ventilation ducts, pipes, roofs and other surfaces. The material has improved technical parameters and, unlike mineral wool in slabs with high rigidity and density, allows it to be used for elements with complex geometries.

The insulation has high performance and technical characteristics and is sold at an affordable price. Roll insulation is used both in repair and capital construction to increase the thermal insulation properties of surfaces:

basement;
attic;
balcony;
gender;
ceilings, etc.

Standard roll insulation based on mineral wool under wallpaper on walls in a residential area allows you to increase the temperature by several degrees by reducing heat loss.

Additionally, the material prevents the development of dampness, the appearance of fungus and mold, and if there is an uneven surface, it hides flaws without additional work.

The wide range of application of mineral wool in rolls suggests its versatility. The material is practically indispensable in modern areas of construction; it allows you to create a truly functional and durable layer of thermal insulation both in apartments and houses, as well as in outbuildings, factories, saunas, baths, etc.

Particularly important is the ability of the material to contact pipes and surfaces of ventilation shafts. In this case, roll thermal insulation is installed primarily due to the elasticity and flexibility of the material. The rolls are easy to use and allow you to finish uneven surfaces, including at sub-zero temperatures.

Advantages of thermal insulation in rolls

Comparing roll insulation with ordinary slabs based on mineral wool, the advantages of the first are obvious. These include:

Minimum thermal conductivity indicators, including among budget models.
Resistance to atmospheric conditions, temperature changes, rodents and microorganisms while maintaining basic thermal insulation properties.
A wide selection of materials based on different types of mineral wool for insulating surfaces with different performance characteristics and features.
Resistance to high temperatures (up to 700 degrees Celsius), open flame.
Noise-reducing properties, which allows you to increase the level of heat and sound insulation.
Ease of installation.

Rolled thermal insulation based on mineral wool also has a small drawback - high vapor conductivity, which will require the installation of a vapor barrier layer.

Types and characteristics of thermal insulation in rolls

The insulation in rolls is based on mineral wool, which can be presented in several versions:

in the form of basalt wool;
glass wool;
slagging.

Materials based on basalt wool are created using the technology of melting rocks to form thin rocks woven into a single carpet.

To produce materials based on glass wool, remelted glass waste is used, which can significantly reduce the cost of finished heat insulators.

For thermal insulation in rolls based on slag wool, waste from the metallurgical industry is mainly used. Compared to insulation based on the above-described insulation based on basalt wool and glass wool, it is the cheapest.

Each of the mentioned thermal insulation materials has its own set of characteristics, despite the fact that they are all an improved version of mineral wool. For example, glass wool is quite resistant to high temperatures. The heat insulator is capable of withstanding up to 450 degrees Celsius; when the temperature rises above this mark, the surface is destroyed and cannot be restored.

Materials based on glass wool have the highest density and thermal conductivity. The rolls are non-flammable, do not smolder, cope well with vibration manifestations, suppress sound vibrations and, what is important, do not shrink regardless of the length of service life.

Among the disadvantages of materials based on fiberglass wool, it is worth noting the instability to moisture, as well as the unpleasant consequences that arise when it comes into contact with human skin.

Thermal insulators based on basalt wool in rolls can withstand high temperatures up to 700 degrees, have excellent thermal conductivity and density. Unlike heat insulators based on fiberglass wool, the materials are able to resist moisture while maintaining basic performance characteristics even after getting wet. Thermal insulators belong to the group ecologically safe materials, not capable of causing allergic reactions.

Slag wool is thermal insulation for insulating surfaces whose operating temperature will not exceed 300 degrees Celsius. The density of materials reaches 400 kg/m3, thermal conductivity ranges from 0.046 to 0.048 W/m*C.

Temperatures exceeding the specified limit will lead to melting of the slag wool with destruction of the structure. Depending on the manufacturer, you can choose materials for thermal insulation based on slag wool with suitable parameters: length - from 3 to 6 m, width - from 0.6 to 1.2 meters, thickness - from 50 to 150 mm.

Heat insulator with foil surface: features

Foil thermal insulation materials have one main feature- a side with a layer of foil designed to reduce the impact of ultraviolet rays on the surface and provide additional protection from moisture. They use materials for insulating indoor surfaces with a base of different types of wool.

You need to work with foil thermal insulation using a special technology, observing some nuances, for example, not forgetting about a small gap (no more than 1.5 cm) between the finish and the thermal insulation material. This is important because as the temperature rises, the insulation will maintain the temperature, transferring it to the back wall, returning it back to the walls, but not into the room, as necessary.

Another important nuance - unlike insulation in rolls based on basalt, fiberglass or slag wool, foil insulation is mounted on the sheathing, placing it overlapping and treating the joints with insulating material.

Tips for choosing thermal insulation in rolls: what you need to know

Summarizing all of the above, it remains to note a few important nuances regarding the choice of materials based on roll-type mineral wool for insulation. Experts recommend first of all taking into account the type of surface and purpose. It is necessary to select materials suitable for thermal insulation of certain surfaces: wood, concrete, brick, etc.

You should not write off the thickness of the base, taking into account temperature indicators and precipitation in the region, especially when it comes to external insulation.

When purchasing materials for thermal insulation based on any of the listed types of wool, you should pay attention to the integrity of the packaging. It is strictly prohibited for moisture to form on the packaging material.

Each of the above types of insulators has its own characteristics, advantages and disadvantages, so the choice must be made after careful analysis, depending on the required functionality.

Roll insulation is a material with a low thermal conductivity, which is additionally characterized by sufficiently low rigidity, but at the same time holds its shape well. Coatings of this type are flexible, which allows finishing areas of complex configurations. Laying such material is not difficult. However, it is important to choose the right dimensions. Insulation in rolls is attached end-to-end; it is unacceptable to leave significant gaps between adjacent sections of thermal insulation. This will lead to the formation of cold bridges.

This type of material is universal, due to its properties (low rigidity and density, flexibility). This means that it can be used on various objects intended purpose(private, economic, public, etc.). However, it should be remembered that each type of such material may have restrictions on its use, for example, if it does not meet operating conditions. Roll insulation is suitable for installation on horizontal and vertical surfaces. It is dense enough to maintain its shape.

A coating with a metallized layer is installed on objects and surfaces where it is important to provide the highest level of protection against heat loss: in baths, saunas, when installing water/electric heated floors, etc. The desired effect is achieved due to the presence of a heat-reflecting layer.

Roll insulation is the only affordable materials that are suitable for protecting surfaces with complex configurations: with differences in levels (stepped), bends, joints, and hard-to-reach places. This opportunity due to flexibility and low rigidity.

Directions for using this type of thermal insulation:

covering walls outside and inside for decorative finishing of any kind (hard boards, soft materials and even wallpaper);
floor protection, in this case the roll insulation is protected from deformation by the lathing;
insulation of flat/pitched roofs;
reduction of heat loss through the ceiling;
protection of pipes for various purposes.

Types of materials in rolls

There are two groups of insulation materials, characterized by flexibility, low density and rigidity:

Based on expanded polystyrene, polyethylene. Such materials are characterized by a closed-porous structure, which is achieved by foaming the raw materials. As a result most volume is a gaseous medium. By foaming polyethylene, a flexible coating of small thickness is obtained. Roll insulation of this type is characterized by low thermal conductivity, wear resistance, and lasts a long time.
Mineral wool is presented in varieties: glass and slag wool, basalt or stone wool. These are natural insulating coatings characterized by low thermal conductivity. Disadvantages include low strength, tendency to sag during operation, and hygroscopicity. The last of the properties is the reason for the short service life of the coating. This insulation is suitable for walls, floors, ceilings, attics, basements, and roofs. If you provide protection from moisture in areas with high loads, you can avoid deformation of the coating.

Foam insulation is divided into types, taking into account differences in the production method:

physically stitched;
chemically cross-linked;
gas-foamed.

The first 2 options are characterized by similar properties, but are manufactured using different technologies. In addition, insulation materials are divided into types, taking into account differences in structure: foam with additives (fire retardants), foil. The last option has improved properties. It not only reduces heat loss, but also reflects thermal radiation, returning it back to the room.

Glass wool

The material is based on glass industry waste and sand. Raw materials are exposed to high temperatures (+1450°C). During the melting process, the finest fibers appear. To obtain a thermal insulation material, a binder is added to glue the fiberglass together. Then molding occurs. In order for the binder component to obtain the desired properties, it must undergo a polymerization process. At the last stage, the material acquires a yellowish tint as a result of dyeing.

This type of heat-insulating layer protects different types objects. Glass wool is a universal coating option. However, when working with it you need to use tools personal protection(respirator, glasses, gloves, closed clothing). This is due to the fact that the insulation contains particles that are characterized by small mass and can be released into the environment under the influence of external factors. Dust enters the respiratory tract, settles on the skin and mucous membranes, which provokes tissue irritation.

To slightly improve the strength indicators, the rolled material is reinforced. The disadvantages, in addition to the release of abrasive particles, include relatively low thermal conductivity. In terms of this parameter, the insulation is inferior to its foam counterparts. Another disadvantage is hygroscopicity. Overwhelming majority mineral coatings intensely absorbs moisture.

Advantages of glass wool:

good sound insulation properties;
sufficient level of strength;
the material is lightweight, which means it will not weigh down the structure;
installation does not require special skills;
flexibility;
vapor permeability;
fire safety;
elasticity, due to which the insulation can restore its original shape;
small width means glass wool will not hide the space;
resistance to mold and fungi;
insulation is unattractive to rodents.

When choosing, not only positive/negative qualities are taken into account, but also coating parameters. Glass wool is characterized by the following properties:

the thermal conductivity value is in the range of 0.039-0.047 W/(m*K);
water absorption coefficient of glass wool for partial immersion - 15%;
This type of insulation is used at a temperature of -60…+250°C;
upon contact with water during the first day, the coating will absorb water in the amount of 1.7% of the total volume of thermal insulation material;
sound absorption rate: from 35 to 40 dB.

In terms of thermal conductivity, glass wool is similar to the following insulation materials: mineral wool, expanded polystyrene.

Izolon

This is foamed polyethylene foam, which is characterized by a closed-porous structure. Available in the following varieties: simple, with a foil layer on one or both sides. Izolon is a fairly dense, but at the same time soft insulation. Its characteristics:

the average thermal conductivity is 31 W/(m*K);
density - 33 g/m³, with a decrease in the value of this parameter, thermal conductivity increases;
the water absorption coefficient is 1%, which indicates that the insulation has no tendency to absorb moisture;
the material does not allow steam to pass through;
the ability to perform its main task (reducing the intensity of heat outflow) at low temperatures - down to -60°C, while the insulation does not lose its properties, does not break, does not deform;
service life is about 100 years;
resistance to negative factors is noted: precipitation, high loads;
no toxic substances are released during combustion;
the material is environmentally friendly;
Izolon insulation protects the object from noise, and a decrease in the intensity of sound waves is noted even with minimum thickness material.

If we consider the foil coating, we should highlight its ability to reflect heat. The insulation reflects 97% of the heat back into the room. Isolon is not deformable. This means that under the influence of moderate loads it retains its properties.

Plates in rolls

In this case we are talking about materials with increased rigidity, which are formed into rolls. These include basalt wool. This material is characterized by a fibrous structure and is superior to glass wool in terms of hygroscopicity and thermal conductivity. In addition, basalt wool in rolls is almost no different in density from isolon (30 kg/m³). Thermal conductivity of the material is 0.039 W/(m*K). In terms of water absorption coefficient, the insulation is inferior to foam analogues (15%). The main advantage of this coating is its non-flammability.

Roll Size Chart

For comparison, we take insulation whose thickness does not exceed 50 mm. This is due to the fact that more massive rolled thermal insulation materials roll up much worse. The review involves fiber coatings. Manufacturers of insulation in rolls:

To compare coverages by cost and determine the most suitable option, take into account the number of strips in the package.

conclusions

Rolled thermal insulation is in many cases preferable because it is characterized by flexibility. In addition, the material of this group has low thermal conductivity, which allows it to be used to insulate an object. However, it should be borne in mind that fiber roll coatings do not tolerate contact with liquids well, so they must be carefully protected with waterproofing.

If you plan to use foam insulation, it is important to remember that they do not allow steam to pass through, which means the microclimate in the room may worsen. To avoid negative consequences when installing insulation of this type, it is recommended to install supply and exhaust ventilation or increase efficiency natural circulation air in the room.

During construction or repairs, walls, ceilings, floors and other surfaces are covered special materials, to prevent heat loss during the cold period and was not bothered by the heat in summer season. One of them is roll insulation, often used for large areas.

Advantages of roll material

This material has many advantages. The main thing is that the insulation in rolls does a good job of maintaining optimal indoor temperatures. There are other advantages:

Main types of insulation

Thermal insulation in rolled rolls can be used both for external and internal laying. There are options specifically designed for pipes and communications. Roll insulation for walls directly under the wallpaper is also available for sale.

The raw materials used for their production are also different. Thermal insulation made from mineral components is the most common. Foamed polyethylene is also popular. Natural insulation materials like corks are less common and used. Some types have an additional layer in the form of foil or paper. Let's consider each option in more detail.

Special thermal insulation coating

To improve the performance of their products, companies that produce rolled thermal insulation add certain coatings. The basis under them may be different.

Types of mineral wool in rolls

There are several varieties of insulation in this group. Their structure is the same, they differ in composition.

Any type of wool must be covered with a vapor barrier, especially in rooms with high humidity. And she also holds back tiny particles fibers that appear over time and negatively affect a person. Raw materials often contain formaldehyde, which also affects health. High-quality rolls should have a minimum of this substance

For laying mineral wool The frame must be installed. On the walls, the panels that hold it in place are pressed firmly so that the canvas does not move out over time. For the necessary protection from the cold, the number of layers can be increased.

Manufacturers often divide their products according to the purpose of the insulation. For ceilings and floors, the rolls will be lighter. For the main floor, walls, and other surfaces, the density of the material is usually increased. Due to this, the dimensions of the roll also change:

length from 3 to 8 meters;
thickness in 3 options (50 mm, 100 mm, 150 mm);
width from 0.6 m to 1.22 m.

Manufacturers of insulating wool

Construction stores offer a wide selection of mineral wool. Let's look at the features of materials from some companies specializing in this area:

Has many positive qualities. It is obtained by filling heated polyethylene with gases. As a result, a mass is formed with many closed bubbles inside, which subsequently hardens. For special strength, it is also “cross-linked,” i.e., the bonds of molecules are strengthened chemically.

Therefore, they are available for sale two options: stitched and, accordingly, unstitched. Both types have very low thermal conductivity, but the first one still has better characteristics, and therefore costs more (its density is 30 kg/m³). The general properties of the materials are:

The difference is that cross-linked polyethylene foam is capable of absorbing sounds well, but its brother cannot boast of this. It works worse as a sound insulator. Under mechanical stress, the uncrosslinked version loses its shape irrevocably. Cross-linked has greater compressive strength, which means it can be used for insulating horizontal surfaces.

Due to the thinness of the material, rolls can be up to 30 meters in length, width from 0.6 to 1.2 m. Thickness reaches 1 cm. Negative nuances for polyethylene are flammability and current conductivity (electricity passing nearby must be well insulated) . To secure the material to the wall, special glue is required.

Penofol brand polyethylene foam

Penofol insulation - appeared recently, but has already stood out among its peers. It is not destroyed by weather conditions and aggressive environments. Thermal insulators from this company have several varieties:

the foil covering can be fixed on one or both sides;
rolls with an adhesive layer (even more simplifies installation);
specialized type of insulation for communication networks;
insulation for harsh conditions with a thickness of up to 40 mm.

The combined technology makes it possible to further reduce the thermal conductivity of insulated surfaces. A moisture-resistant and durable material that does not require the cost of vapor barrier, can be used in various directions. Does not lose its properties in the temperature range from -60 to +100 C°.

Cork insulation for surfaces

An environmentally friendly and durable raw material for the production of thermal insulation is cork oak bark. Absolutely natural ingredients make the rolls safe for health. The crushed bark is combined with organic glue and pressed. Thickness ranges from 2 to 6 millimeters. The length of the roll reaches 10 meters, the width is mostly one meter. Most often, in this form, the cork goes under wallpaper, on a substrate for laminate or “warm flooring”.

Thermal conductivity index not inferior to mineral wool, but the layer used is much thinner. Cork insulation is not flammable, does not absorb water well and retains noise. However, its density is high, and therefore its weight is high. The safety factor is high, the service life is stated to be up to 50 years. The negative side is the price of “naturalness”; compared to the others, it is quite high.

This insulation is produced mainly by Portuguese companies: Wicanders, Izora, Amorim. They offer a wide range of insulating rolls, which can also serve as wall decoration. Installation is also simple; basically, the cork is “set” on glue.

Modern technologies provide a huge selection of heat insulators for any premises and structures. The selection criteria are based on what surface needs to be covered and how much the buyer is willing to pay for it to maintain comfort in their home.
