Technology of insulating the loggia with penoplex and finishing. Technology of insulating a loggia with penoplex. Features of external insulation of a balcony with penoplex

IN last years many people have reconsidered their attitude towards balconies and loggias. Previously these small extensions, which are available in most apartments, were used by the owners as a warehouse for various unnecessary things.

But in fact, these are several “squares” that can be arranged and used with much greater benefit (especially considering that there is an acute shortage of free space in the house). However, in order to be comfortable on the balcony in winter, certain finishing is required. First of all, we are talking about insulation with.

1 Why insulate?

If your apartment has a balcony for which no thermal insulation work- you're on own experience You know very well how “cosy” it is there in winter. Moreover, it does not matter whether it is glazed or not - the lack of thermal insulation in any case leads to the fact that heat instantly leaves the room.

As a result, the temperature on the balcony is not much different from the temperature outside the window, and with the onset of cold weather they try not to go out there again.

Thus, the relevance of insulation is easily understood without further clarification - this must be done in order to create favorable microclimate. This concerns two factors at once:

1. Dryness – the balcony should be dry, and this will help.
2. Temperature - it should be maintained, if not at room temperature, then at least be significantly above zero.

The first point is no less important than achieving warmth. Poor finishing (a problem common among many) of the balcony, often done during the construction of the house and rarely updated, leads to the fact that wind blows through existing (or appears over time) cracks and moisture from precipitation gets inside.

As a result, dampness reigns in the room. This negatively affects both everything that is inside and the structure itself - the concrete slab in particular. Over time, moisture and cold lead to the fact that it begins to deteriorate - it cracks, pieces break off from it.

If you live in a house that is at least more than 10 years old, and the balcony in the apartment has not been insulated, pay attention to the condition of the slab. Surely the influence of the above factors is already noticeable on it.

In addition, dampness and cold are transferred to the room adjacent to the balcony - often this room is noticeably colder than others. So even if you don’t plan to install anything useful on the balcony, finishing it with thermal insulation materials is needed at least to make better microclimate inside the room to which it is adjacent.

1.1 Why Penoplex?

Balcony insulation with Penoplex, as well as (extruded polystyrene foam), is chosen quite often. This material, which is the closest analogue of foam plastic, is easy to use with your own hands, and the technology is so simple that even a person who has never encountered repairs can cope with the task.

The choice of this particular insulator is easy to explain - it has all the necessary properties that a buyer is looking for when he needs to do the work himself. In particular, these include:

• lightness – which simplifies both transportation and installation;
• ease of processing - if necessary, the sheet can be easily cut into the required parts;
• resistance to moisture;
• low thermal conductivity (about 0.035 W/mK);
• safety for humans (with normal conditions) like .

Separately, we should dwell on the third point - when insulated with extruded EPS, the chance of damage to the material upon contact with moisture is minimal (which is relevant for a balcony).

By the way, for this reason it is not recommended to insulate the structure with mineral wool - it tolerates dampness much worse: it gets saturated, and because of this it crumples and cakes. In addition, working with your own hands is much more difficult - you need to use protective equipment.

Ordinary polystyrene foam (which differs from PPS in its characteristics - they are slightly worse) also does not “like” moisture very much. Substantial harm It will not harm him, but his properties will be lost much faster.

However, with due attention to waterproofing, insulating a balcony with polystyrene foam can be done - after all, this technology has been used for decades (like the technology of mineral wool insulation, by the way), and lasts for more than one or two years. And in terms of money, such thermal insulation is very cheap.

2 Stages and nuances of work

Insulating a balcony with polystyrene foam (as, indeed, with any other material) can be done in two ways:

1. Outside.
2. From within ().

The first technology is more effective, but it costs more and is more difficult to work with - it is unlikely that you can do it yourself (unless the apartment is on the 1-2 floor, and the balcony can be reached from the ground or from the stairs). It is effective in that it prevents contact of moisture and cold with the structure itself - the partition.

In other cases (when the apartment is located on upper floors) you won’t be able to handle it normally with your own hands, and for this you will have to use the services of specialists.

It doesn’t cost too much, however – so if you want to create the greatest possible comfort on your balcony, it’s better to pay for these services. Among the disadvantages of such a procedure (besides the fact that it is performed only by specialists and costs money), one can also note the fact that it can only be carried out in warm, dry and windless weather.

2.1 About insulating the balcony floor

Creating a screed on a balcony is almost never possible - unless the apartment is not located on the first floor and does not have a reinforced extension. The concrete layer will put significant pressure on the slab - so it is better not to use this technique (especially for old houses where the slabs are no longer in ideal condition).

Most often, insulation is carried out by laying lags. This procedure is performed as follows:

1. The stove is completely cleaned of finishing materials, dirt and dust.
2. The slab is checked for integrity, especially in the area where it connects to the wall.
3. If there are cracks and/or chips, they need to be covered with plaster.
4. After the solution hardens, the surface is primed several times.
5. Lags are being laid - wooden supports, between which the insulation will lie. Their height should be greater than the planned thickness of the insulation.

The step between the lags should not be too small - in this case, Penoplex will have to be cut into large quantity parts. The optimal minimum is 50 cm.

1. Several layers are laid on the floor, between the joists. polyethylene film(or special waterproofing), with entry onto the walls as with.
2. Penoplex is cut into segments the right size. It is optimal if one segment is used for one “compartment”.
3. Penoplex is laid between the joists on the underlying film.
4. The insulation is again covered with film on top - again, preferably in several layers.
5. Placed on joists rough coating and further finishing is carried out.

2.2 Stages of insulation from the inside (video)

2.3 About insulating the balcony partition (wall)

This point is the most important - since it is the partition that directly borders the street (for residents of the extreme floors, special attention should also be paid to the floor or ceiling - depending on where exactly they live - on the top or first floor).

The procedure itself is extremely simple:

1. The partition is freed from finishing materials (if any).
2. If it is concrete, it can also be primed.
3. The gaps/holes in the partition are eliminated (the method depends on what and how exactly the partition is made of).
4. An adhesive solution is prepared.
5. Penoplex is cut into segments of the required size.
6. Penoplex is glued to the surface using the prepared solution.
7. The joints between the segments are glued with construction tape or foamed.
8. Glued on top of Penoplex vapor barrier film(this step is not mandatory, but recommended).

In this case, the thickness of the material should be significant - in order to create a significant barrier to moisture and cold.

2.4 About ceiling insulation

For those who don't live in top floor, the ceiling also needs to be insulated - albeit not as significantly as for those who do not have upstairs neighbors. This must be done to prevent heat loss - since warm air will go up.

The thickness of the thermal insulation for the ceiling does not have to be significant - it will be enough to use a 5-centimeter sheet of Penoplex - and this will already give a significant and tangible result.

The procedure itself is no different from the above-mentioned sequence of actions - except that in the end, instead of the usual plastic film, it is better to enhance the effect by using a foil vapor barrier (this, for example, can be Penofol).

In this article I will tell you how to properly carry out the work and insulate your balcony using Penoplex - one of the best thermal insulation materials. But if you make mistakes and fasten the material incorrectly, then there will be little benefit from such thermal insulation. And you will learn how to avoid this by reading the article to the end.

Description of work

We will figure out how to insulate three parts of a balcony or loggia:

• Walls;
• Ceiling.

Most often, all surfaces are thermally insulated, but you can limit yourself to just walls. If the balconies above and below are warm, then insulating the floor and ceiling does not make sense. You need to select the required sections and follow all the recommendations in order.

Walls

It is through this part of the structure that the most cold penetrates onto the balcony, so it is important to properly insulate it. First, let's figure out what materials will be needed when carrying out the work.

Material	Recommendations for selection
Penoplex	Use sheets with a thickness of at least 50 mm. When choosing, do not forget to add extra, since the elements will have to be cut and waste will be generated. The price for a package containing 8 sheets measuring 1200x600 mm is about 1500 rubles
Waterproofing material	If the walls do not allow moisture to pass through, then it is not necessary to lay it. But if dampness penetrates, then it is better to make a waterproof barrier. Many people use material with a reflective layer to retain as much heat as possible in the room.
Wooden block	Used if you will be doing sheathing. The thickness of the elements must be no less than the insulation
Polyurethane foam	This composition fills all the cracks and joints. Foam can also be used if the sheets are attached to the surface without sheathing
Dowels for thermal insulation	They are used when Penoplex is attached without lathing. Their length should be such that the spacer part completely extends into the base

Do-it-yourself insulation of balcony walls with Penoplex is done in two ways. The first option is to fasten the sheets to the surface using dowels.

The technology for carrying out the work is as follows:

• The surface is cleaned of dust and debris; if there are protruding fasteners on it, they should be removed. Cracks and damage are repaired cement mortar or filled in polyurethane foam;
• Penofol is attached in different ways. If the base is wooden, then you can use self-tapping screws or a construction stapler. For concrete and brick surfaces The easiest way to glue the material is with liquid nails. Just apply the composition around the perimeter and a little in the middle and press firmly to the base;

The joints between sheets of reflective material are glued with special metallized tape.

• Next, you need to try on the insulation sheets and mark them for cutting. You can cut the material with a regular wood hacksaw with small teeth;
• Fastening is done as follows: the sheet is placed against the surface, after which a hole for the dowel is drilled directly through it. For work, a hammer drill with a drill of the appropriate diameter and length is used;

• Dowels are inserted into the holes, after which nails are driven into them. Thus, the insulation is fixed very quickly and reliably. There should be at least 2 fasteners per sheet, but it is better if there are 3-4 of them;

• If there are wide gaps at the joints, they are filled with polyurethane foam. If the connections are tight, then to ensure reliability you can glue them with foil tape. On this this type the work can be considered successfully completed, then finishing proceeds using the chosen method.

Let's figure out how to insulate a balcony using sheathing.

Instructions for doing the work yourself in this case look like this:

• First of all, you need to secure the sheathing to the surface. Ideally, the pitch of the elements will be equal to the width of the Penoplex sheets. If the lathing is located more often, then the distance between the posts should be a multiple of the width or length of the sheet in order to cut it in half or into 3 parts and thereby avoid waste. Reflective material can be placed under the structures;

• The easiest way to fasten elements is with dowels quick installation. Their length should be 40-50 mm greater than the thickness of the bar;
• Insulation is placed in the sheathing and cut to size. Is not mineral wool, and it’s not worth cutting the sheets more than necessary, they simply won’t fit into their place. There is no need to fasten the material, it should hold on as is;

• All cracks must be carefully filled with foam. This will prevent heat loss through the surface. After the composition has dried, all excess can be cut off with a construction knife;

• The lathing is made finishing selected material. Here you can use anything: from wooden or plastic lining to drywall or wood-based materials.

Floor

Floor insulation can also be done with or without lathing. The materials used are the same, so let’s immediately start looking at the work process.

First, let's figure out how to insulate a surface without a wooden structure:

• The surface is freed from all excess and cleaned of dust and debris. After this, you need to check the floor using a level; if there are uneven spots on it, they should be removed. Alignment can be done as follows: cement compositions, and self-leveling mixtures. The level difference should not be more than a few millimeters;

• Next, the insulation is installed. Everything is simple here: the sheets are arranged so that they fit tightly to each other and completely cover the surface. In order for the elements to stand in place and not move, they need to be fixed with dowels, and one fastener is enough;

• Next, you need to lay the reinforcing metal mesh and pour a screed 4-5 cm thick. If desired, you can also install a heated floor system, then you will have full heating on your balcony. In this case, the thickness of the screed is made such that there is 3 centimeters of solution above the system;

• After the screed has dried, you can lay any flooring: from tiles to or laminate.

The second solution involves laying bars.

The process consists of the following steps:

• The arrangement of the elements is selected depending on the configuration of your balcony. The distance between the lags should not exceed 60 cm, this is important for reliability;

• The easiest way to fasten elements is with quick-installation dowels. They are located in increments of 50 cm. Here it is important to fix the block in the desired position so that it does not move later;
• Next, Penoplex is cut into pieces of the required size and placed in the sheathing. Don’t worry, if there are small gaps at the joints, you can fix them without any problems;
• All joints must be filled with polyurethane foam, this will not only insulate the surface, but also additionally secure the material;

• After the foam has dried, you can lay any floor covering.

Ceiling

When considering the insulation of a loggia with Penoplex, one cannot help but touch on the ceiling. There are also two options for carrying out work.

First of all, let's look at the structure without sheathing:

• To begin with, you should attach a sheet of Penoplex to the surface and drill at least 2 holes for fastening;

• Next, the elements are fastened; here it is important to join them well in order to cover the surface as best as possible;

• All cracks and joints are carefully filled with polyurethane foam. Pay special attention to the perimeter connections; the most heat is usually lost through them;

• After the foam has dried, you need to fix the mesh on the surface and putty it.

As for the option with lathing, everything is simple:

• First of all, you need to secure the frame, and it is very important to level your elements. If the surface has significant unevenness, then it is best to secure the block using drywall hangers. As for fasteners, the same quick-installation dowels are used, the length of which is selected according to the situation;

• Next, you should secure the Penoplex; in this case, it is best to use special glue. It is applied as shown in the photo. After this, you need to carefully press the element to the ceiling and glue the following:

• After the glue has hardened and the sheets are held firmly, you can begin sealing the seams. All joints are filled with polyurethane foam to eliminate defects that are sure to exist;

• After the foam has hardened, you can finish the ceiling with any suitable material.

You can cover the surface under the finishing with reflective material, but if there is a warm balcony above you, then there is no point in this.

Conclusion

Using the recommendations from this review, you can easily insulate a balcony with Penoplex, even without experience in this area. Be sure to watch the video in this article. If you have questions, write them in the comments.

Among the range of insulation materials, the most popular option is penoplex. In addition to its affordable price, this material differs from existing analogues in its reliability and good thermal insulation. It is quite possible to insulate a balcony with penoplex yourself, without the help of a professional team of builders. For a successful result, you should purchase insulation in the required volume and understand technological features process before starting work.

• self-insulation (personal experience)
• Using the example of Moscow

Characteristics of penoplex

Penoplex is extruded polystyrene foam, which is produced in the form of slabs. The thickness of individual elements is from 20 mm. The high degree of efficiency is confirmed by the use of this material for insulating oil pipeline networks, covering airfields and roads. The use of penoplex is widespread even in extremely low temperatures.

The price ranges from $10-45 per package. Finishing cost construction crew 5-10 $/sq. m (average prices in Moscow).

Main advantages:

• Due to the structure of many closed cells with air, this insulation has low thermal conductivity (mineral wool and polystyrene foam are less stable);
• The level of efficiency and optimal dimensions of the tiles allow you to economically use the balcony area when creating reliable design. This effect is of particular importance in small apartments;
• Eco-friendly composition (safer alternative options insulation);
• The structural features ensure maximum moisture resistance - about 100%. This condition explains the absence of rotting and long service life (50 years or more). The material is successfully used in areas with high humidity;
• Low weight with high strength. The slabs are able to withstand significant compressive loads without deforming;
• Opportunity self-installation. The slabs are easy to work with during preparation (cutting) and installation;

Fire safety is one of the important indicators that you need to pay attention to when purchasing. The marking must contain the letter C. This designation indicates the presence of flame retardants that resist fire.

Flaws:

• The material is not resistant to influence sun rays, therefore penoplex is not used to insulate the outer part of the balcony;
• When interacting with petroleum products and solvents, the slabs are destroyed.
  Study the ingredients carefully construction foam and adhesive for installation before purchasing;
• The cost of penoplex is higher than traditional insulation. You can save money by installing it yourself.

Important points:

• The slabs are installed along the entire perimeter of the room, including the walls, ceiling and floor surfaces.
  If you lay the material only on the walls, then the costs will be ineffective - the room will remain cold. This circumstance plays a big role when combining the balcony part with the apartment;
• To install penoplex, you do not need to build a sheathing frame. Similar design promotes heat loss through cold bridges in the structure.

Preparing for insulation

To build a warm balcony you need to purchase: polyethylene with foil (provides correct vapor barrier), slabs 40-60 mm thick, boards for leveling the floor, or a special screed, timber, fasteners, finishing material.

The day before repair work It is necessary to organize an electrical outlet for connecting the antenna, the Internet, and various electrical appliances. Additional heating is also provided at the preparatory stage ( infrared heating, warm floor).

Correct installation of insulation in stages

1. The room should be cleared of unnecessary items before starting the insulation process.

2. The enclosing surfaces are leveled - they should be free of screws and cracks.

3. Using fasteners (dowels), the slabs are fixed (the sheets are cut with a knife if necessary).

A disc-shaped dowel used for mounting sheets on walls (“umbrella” or “mushroom”).

The sheets can also be secured using a special mounting adhesive, if the surface is previously leveled.

Apply adhesive composition onto the surface in dots (5-7 pieces per 1 sq. m) or in a zigzag. The walls should be coated with a primer for better adhesion.

4. After joining the plates, fill the gaps special foam to create a sealed structure. The excess part of the polyurethane foam is cut off after drying. Eliminate use winter version foam sealant containing toluene.

5. In order to smooth the joints, you can use tape. The result will be a flat surface;

6. The high moisture resistance of the material allows for the absence of special vapor barrier. However, if you decide to organize an additional layer, it can be made of polyethylene film covered with foil (penofol). Thus, the balcony room will be protected to the maximum from moisture. The foam layer should be oriented with the foil facing outward.

Polyethylene foam with metal tape acts on the principle of a thermos, additionally insulating the room;

7. Another way to provide vapor barrier is to cover the surface with special plaster and plasterboard;

Creating a warm floor structure

After covering the balcony with penoplex, it is necessary to complete the insulation of the floor.

There are three finishing options:

1. Easy option floor. A base is created from timber in two tiers, the elements of the two layers are fixed perpendicular to each other. Insulation is placed in the structure, then the cells are sewn up with sheets of plywood or boards. The resulting coating can serve as the basis for the final layer.

2. Concrete screed or sand-cement screed(thickness 40 mm). The leveled floor is tiled. Required condition during installation: create a 10 mm gap with polyurethane foam around the perimeter of the floor (between the walls and the screed). The weight of the structure is significant, it is necessary to carry out preliminary calculations by load.

3. Installation of heated floors. Installation instructions are included with the specific system.

The insulated loggia allows you to increase usable space apartment and use this room as an office, gym, kitchen. Warm balcony– this is a great place for growing flowers and relaxing, which you can use even in winter period. Owners small apartments show particular interest in this issue. Step-by-step instructions and photos will help you insulate a loggia or balcony with penoplex yourself, and also cope with the task in a short time.

How to insulate a balcony from the inside with your own hands?

Apartment owners often decide to install heating on the balcony so that even in cold weather it is comfortable to use this part of the apartment. The material is easy to install and even a non-specialist can cope with the task of insulating a loggia using it. Using penoplex for insulating balconies and loggias has many advantages, namely:

• moisture resistant;
• lasting;
• easy;
• durable;
• environmentally friendly

Experts include the disadvantages of penoplex as low noise insulation characteristics, destruction under the influence of direct sunlight and the release of acrid smoke when destroyed by fire. However, solving these problems will be very simple even for a person without experience. For example, it is recommended to cover penoplex with cladding immediately after installation. If the apartment is located on a noisy street, then it is better to give preference to another insulation, otherwise it will always be noisy on the loggia, even with the windows closed.

To hold everyone preparatory work and installing penoplex with your own hands, the apartment owner will need to purchase materials and assemble the following set of tools:

• foam sheets;
• sealant;
• a can of polyurethane foam;
• hammer drill and screwdriver;
• self-tapping screws;
• putty knife;
• Ceresit glue SM11 or mounting dowels.

Insulation of the loggia with penoplex

How to properly insulate a loggia/balcony yourself? First of all, you should follow the step-by-step instructions, completing the list of works:

1. The balcony or loggia must be completely emptied.
2. Install windows or replace them if they need it.
3. Dismantle the old insulation and clean the ceiling and walls of other materials.
4. Seal all cracks and cracks with sealant and prime them first. Blow out large spaces with foam, paying special attention to the holes in the floor.
5. Level the surface of the walls and ceiling.
6. Cover metal lattice fencing with moisture-resistant plasterboard or plywood.
7. Prime the entire surface well and let everything dry thoroughly.

Now everything is ready to insulate the balcony/loggia and you can begin installing the penoplex yourself.

Sealing seams on the balcony

1. The very first floor is insulated and for this purpose it is done concrete screed, sheathing and insulation is installed.
2. To attach penoplex to the walls, work begins from the corner of the room. Ceresit glue is applied to the insulation and the penoplex is carefully pressed against the flat surface of the wall. It is important to check that the entire surface is pressed tightly and no cavities are formed.
3. Every square meter Penoplex is secured with umbrella dowels for reliable fixation. It is worth paying special attention to the perimeter of the sheet and places near windows and doors. 7-8 dowels are used per sheet.
4. All seams are carefully sealed with polyurethane foam or.
5. Installation of a vapor barrier layer using penofol. Particular attention is paid to the joints, making overlaps in these places.
6. Like the walls, the ceiling is also insulated.
7. Installation of lathing from plastic panels or boards - this is the final stage of work. The material is attached to the sheathing, sockets and places for switches are cut in the right places. Then installed decorative skirting boards as shown in the photo.

Do-it-yourself insulation of a balcony with penoplex is not difficult task if you follow the step-by-step instructions

When carrying out work on insulating a loggia, specialists do not use polyurethane foam with toluene, as it destroys penoplex. Craftsmen advise using 40 mm thick penoplex for walls, and 20 mm for ceiling insulation. It is important to follow the installation technology and video and photos will help with this.

Video about insulating a loggia with penoplex with your own hands, step-by-step instructions:

Do-it-yourself insulation of the loggia with penoplex, step-by-step instruction, photos - this is what inexperienced performers who want to save their family’s money are looking for on the Internet. Fortunately, the technology of penoplex insulation is a fairly simple process, so anyone can begin to implement it without having any construction skills or experience.

Loggia has design features, which make it easy to turn it into a full-fledged room. But for this it is necessary to glaze the facade and insulate the floor, ceiling and walls. Selection of materials with thermal insulation properties wide enough. Among the new offers construction market it is worth paying attention to penoplex, which has whole line advantages over traditional materials and is perfect for insulating a loggia.

Penoplex is a material consisting of closed, air-filled cells, which are obtained by extruding polystyrene. The process occurs at high pressure and temperature, which makes it possible to obtain a homogeneous material with a cellular structure, which not only has high performance on thermal insulation, but also on mechanical strength. Freons, which are used for foaming, make penoplex a non-toxic, non-flammable, environmentally friendly substance.

This material is resistant to such chemical substances such as acids, alcohol, inorganic dyes, oils, alkalis, cement. Its low weight reduces transportation costs and makes installation easier.

With sudden temperature changes in the range from -50 to +75 0 C, penoplex does not lose its properties. But it should be protected from direct sunlight and organic substances, such as gasoline, kerosene, oil paints, diesel fuel.

Insulating a loggia with penoplex is convenient primarily because of its small thickness, since this room has small sizes and the use of other materials will reduce usable area. In terms of thermal insulation, a slab with a width of 20 mm corresponds to a 370 mm layer of brick or a 38 mm layer of mineral wool.

An important characteristic of penoplex for insulation is its high moisture resistance:

When immersed in water, the slab absorbs moisture in the amount of 0.4% of its volume in 24 hours.

Advice from experts on how to properly insulate a loggia begins with recommendations for selecting the type of penoplex depending on the following factors:

• future purpose of the room - will it be a separate or connected room common space with an apartment, just a change house;
• the condition of the floors and the type of material from which they are made;
• the number of walls facing the street;
• possibility of establishing additional heating, for example, “warm floor” systems;
• future type of interior decoration;
• the need for internal and external insulation.

By technical specifications There are several types of extruded polystyrene foam, produced in slabs with thicknesses from 20 mm to 100 mm.

Stages of work

The technology of insulating a loggia with penoplex involves a preparatory stage. In this case, surface preparation is carried out (removing dirt, dust, sealing cracks and potholes, treating with antifungal impregnations), laying a layer of waterproofing.

At this stage, the method of laying penoplex slabs is determined.

There are four types of styling penoplex:

• fastening with dowel mushrooms;
• non-adhesive base;
• laying between profiles;
• installation under profiles on strip hangers.

For the first and second types of installation slabs with a chamfer are selected for a tighter connection at the joints. Only glue the material if the partitions are very thin and there is the option of through penetration with a dowel fungus, but the surface must be perfectly flat.

The first two methods of laying insulation are well suited for plaster or putty on walls and ceilings. Insulation of the loggia with penoplex is carried out on the profiles or under them, when interior decoration will be made of plasterboard, PVC panels, MDF, wooden lining. On It is also recommended not to glue the floor slabs, and laid in a frame made of timber.

Do-it-yourself insulation of a loggia with penoplex starts from the ceiling. The first sheet is dotted with glue, lifted and placed in a corner. Holding the stove with one hand, drill holes through the insulation and in the ceiling.

Dowel fungi are inserted into the holes and take root. For 2 dowels are enough to fasten one plate. The next one is laid in the same way, but it is necessary to correctly connect the sheets together using a tongue-and-groove system so that there are no gaps between them.

When laying under drywall, penoplex sheets are cut out in accordance with the size of the gaps between the profiles with a margin of 2-3 mm and placed in niches. But in this case it is impossible to obtain a tight connection between the plates.

To achieve maximum tightness use two methods:

1. laid before installing the profiles on U-shaped tape hangers. To do this, small cuts are made in the slabs. Hangers are inserted into these cuts (the profile will be attached to them), which bend and hold the insulation;
2. installation is carried out in two layers of insulation: the first is laid normally, and the second is staggered so as to cover the joints.

After the ceiling, they move on to insulating the floor. If a screed or “warm floor” is planned in the future, then the slabs are laid using dowel mushrooms, and the joints are sealed with polyurethane foam.

But if you plan to lay flooring, you can install insulating panels between the joists on which the decorative floor will be laid.

All gaps must be blown out with foam or sealed tile adhesive. For insulating floors under laminate or linoleum “floating” laying technology is used, when the slabs are not specially rigidly fastened, but are simply stacked tightly against each other.

The walls are insulated in the same way as the ceiling. For external walls, two layers of penoplex are often laid, but of a smaller thickness. The surfaces of the loggia are common with interior rooms, can be insulated with thinner slabs or finished only with foil vapor barrier.

For parapet and external wall the thickness of the penoplex is selected from 80 mm and the flooring is laid between the slats wooden frame. Better thermal insulation achieved by laying in two layers.

After finishing installing the heat insulator on the loggia, it is important to check the tightness of all joints and, if there are doubts about their reliability, additionally glue them and blow them out with foam. Penoplex may not be specifically insulated from steam loss, but to increase heat transfer, a coated vapor barrier is laid aluminum foil.
