Insulation of plastic windows using Swedish technology. Swedish window insulation technology: materials and tools. Sealing and adjustment
Insulation according to Swedish technology wooden windows and doors
Old, poorly insulated windows are a source of drafts, heat loss, and increased street noise. Meanwhile, even without the funds to install metal-plastic structures, this problem can be solved inexpensively. OknaDel specialists offer window insulation using Swedish technology - using a special groove method "Eurostrip Technology", developed in Sweden, where the name of this practical method comes from.
With us you will forever forget about drafts that spoil appearance rooms paper tapes, “decorating” the windows.
The essence of energy-saving window repair using technology is to seal cracks, gaps, and leaks between frames using an elastic tubular “Eurostrip” placed in grooves specially milled for this purpose. Paired windows are additionally sealed with a so-called inter-frame seal, which has adhesive base. This prevents dust from penetrating into the space between the glass.
Repair of wooden windows is carried out in the following order:
- The sashes of wooden windows are preliminarily adjusted to size, after which a groove is cut along their perimeter using a manual electric milling cutter;
- A sealant is inserted into the cleaned groove and rolled with a roller for reliable fixation;
- Wooden window sashes are hung on hinges, after which distortions are eliminated; it is also necessary to adjust the strikers, restore the operation of the vents, and other adjustments - the window sash should be able to close and open freely, but without the formation of cracks;
- Sealing the window around the perimeter of each glass with silicone sealant.
If the customer, along with window insulation, wants to remove layers of old paint and putty, replace fittings, glazing beads, old glass, or perform other repairs, we are always ready to help. On the company’s website, find the “Restoration” section, which lists many additional services that our specialists will readily provide to you.
Prices for insulating wooden windows using Swedish technology
Order an estimate
The quality largely depends on the type of seals.
Painting the window, depending on the type of insulation, is done before or after its installation. Silicone sealant is considered the best for Swedish technology. Its relative high cost is compensated by its resistance to temperature changes, elasticity, long service life, and insensitivity to paints and varnishes.
In addition to the silicone sealant, two cheaper options can be found on the domestic market. One of them is a rubber seal (analog). It is more rigid, fits worse, and is damaged by the solvents contained in the paint. The third type of seal is a short-lived thermoplastic elastomer, a seal that does not withstand temperature changes. We absolutely do not recommend it.
Compare for yourself:
To restore an old standard double-leaf window, the Swedish window insulation technology can be performed using an original silicone seal, then the work of specialists will cost you about four and a half thousand rubles. But the service life of such insulation is from ten to twenty years. Using an EPDM seal will reduce the cost of work to two and a half thousand rubles, but its service life will also be reduced to one, maximum - three years. Such repairs are only suitable for short-term use, a temporary measure.
Examples of work on: insulation of wooden windows using Swedish technology
Many people have long ago replaced old wooden windows with a “draft effect” with warm metal-plastic ones.
However, there are many citizens who cannot afford such an event yet.
Is it possible to do something similar with old windows to somehow reduce heat loss? It turns out that insulating windows using Swedish technology has long been practiced.
The method for repairing old windows, proposed by the Swedes, is extremely simple: a groove is cut out in the sash along the entire perimeter, in which a seal is fixed - a profiled cord made of elastic material.
The working part of the cord is a hollow tube, and the rib that needs to be inserted into the groove has a “herringbone” or “ruff” cross-section, due to which it is fixed very firmly.
After installing such a seal, the window will close completely hermetically and, accordingly, will become windproof. Additionally, it is proposed to seal the glass with silicone sealant.
The profiled cord used in this technology is called EuroStrip. Currently, it is produced by several companies (including domestic ones) from various materials.
But the most durable are products made from silicone rubber, made in Sweden. It retains elasticity for 15 years (a 10-year guarantee is given), is durable and at the same time is absolutely resistant to temperature changes, mechanical wear, ultraviolet radiation and exposure to paints and other chemicals.
New plastic windows in additional insulation do not need it, but after 5-6 years of window service, it may still be necessary to carry out thermal insulation. , we'll tell you in the article. Protection of slopes and replacement of rubber seals.
We will consider thermal insulation materials for the ceiling and methods for installing insulation.
If you want to expand your living space by combining a balcony with a room, you need to organize good thermal insulation balcony At this link you will find useful information by insulation options and characteristics of each of them.
Advantages
Let's try to evaluate the benefits that this method of window improvement promises us:
- Heat loss can be minimized, because a significant part of it is caused by the seepage of cold street air through the cracks. As a result, the room temperature becomes 3–5 degrees higher.
- By preventing the entry of outside air, we also get rid of street dust. External noise also becomes less audible. This is especially true for those whose windows overlook busy roads.
- After the upgrade, the window will no longer fog up from the inside.
- Only environmentally friendly materials are used.
- Despite all its effectiveness, this method requires purely symbolic costs that even a pensioner can afford.
- Having minimal skills in working with some tools, window insulation using Swedish technology can be done on your own.
- You will need to spend no more than 3 hours on everything.
- Unlike other insulation methods, for example, pasting with paper, this method allows you to open windows for ventilation. Another significant advantage: you will only need to work with windows once, and not at each change of season, as with other types of insulation (in winter you need to glue paper or tape, and in summer you have to tear them off and wash them).
It should be noted that the proposed insulation technology is not always appropriate. If the window being repaired is in a very poor condition, even such modest costs will not justify themselves.
In this case, it would be more correct to set aside this money in order to quickly save up for a new window.
Methods for insulating windows using Swedish technology
The sealing cord can have a diameter from 5 to 12 mm. Which size will be most suitable depends on the width of the gap between the sashes and the frame.
The Swedish seal, as already mentioned, is the highest quality and most expensive. Its price is approximately 34 rubles/m. (with a diameter of 10 mm).
Due to its softness, this material is indispensable in the presence of cracks that are uneven in width.
A purely rubber EuroStrip is somewhat cheaper. It is characterized by a more rigid structure, so it is effective only if the gap has an equal width along its entire length. Upon contact with paint and varnish materials, unlike silicone EuroStrip, loses its working qualities.
The cheapest modification is a thermoplastic elastomer seal. The full name of this group of materials is thermoplastic elastomers. They are not only inferior to silicone cord in elasticity and durability, but also do not tolerate temperature changes well. For EuroStrip of domestic production from EPDM and TPE elastics, sellers ask from 11 rubles/m.p.
Insulation scheme using Swedish technology
In some types of windows, the seal is fixed to the frame (frame). Those who find it difficult to create a groove can glue Eurostrip or sew it with a stapler.
Do-it-yourself window insulation
In addition to the sealing cord and silicone sealant the home craftsman will need a tool for cutting a groove. Many on-call craftsmen perform this work using an angle grinder, but this is far from the best option.
This tool is not able to provide the required accuracy, and if an amateur gets down to business, failure is guaranteed.
Moreover, the groove is quite difficult to complete: it is cut in inner corner, formed by the side surface of the sash and the strip adjacent to the frame when closing. In addition, the groove is made at an angle of 45 degrees to these surfaces. The best way to cut it is with a milling cutter.
Virutex router
Of all the milling cutters on sale, the most suitable for this operation is the Virutex tool.
Do not try to cut the groove with a regular chisel. Even experienced carpenters consider this a hopeless task - you’ll just ruin the window.
It is also advisable to have special tool with a seaming roller, which presses the cord into the groove. Its design is quite simple and its operating principle is reminiscent of a seaming machine used to seal jars when canning.
Stages of work
If the tools and materials are available, you can get down to business. This is what the sequence of actions when repairing a window looks like:
Preparation
The sashes are removed, after which the condition of all window elements is checked. If necessary, you need to carry out reconstruction: fill up potholes, clean out rotten areas and also treat them with putty. Particular attention should be paid to the hinges.
They must be held firmly both on the frame and on the sashes. Loose fasteners should be tightened. If this is not possible, for example due to rotten wood, the loop should be moved to an undamaged area.
If old paint the window has peeled off and needs to be removed and the entire structure repainted. WITH wooden surfaces paint coating very easy to remove with construction hair dryer and some kind of metal scraper. When heated with a hairdryer, the paint bubbles and comes off the wood.
Composition of a window block with insulation using Swedish technology
This effect is due to a significant difference in the thermal conductivity of wood and paint. Remove the paintwork from the concrete wall or a metal product will not work.
Before applying fresh paint, the window elements are treated with sandpaper (first coarse, then fine) and dry.
Making a groove and installing insulation
Before this operation, the glazing should be removed from the sashes. The glass is held in place by glazing beads, which are nailed down.
It is better to cut a groove in the sash outside, since this process is accompanied by the formation of a large volume wood shavings and dust. The milling cutters used by Swedish craftsmen are equipped with vacuum cleaners, but we’ll just go to fresh air so as not to litter the house.
Making grooves
The groove, as already mentioned, should be made in the corner between end surface the sash and the bar on it, which, when closed, is adjacent to the frame (it bridges the gap between the frame and the closed sash). In this case, the axis cross section The groove should be located at an angle of 45 degrees to each of the adjacent surfaces. The width of the groove is 3 mm, the depth is 4 mm.
The groove should not be cut all the way to the hinge - it should end approximately 15 mm from it.
When the sash is cut around the entire perimeter, you can begin installing the cord. It, as mentioned, is pressed using a roller tool.
During installation, it is important to move the roller not only in the forward direction, but also in the reverse direction. This will avoid tension on the cord and thus extend its service life.
Sealing glass on silicone
Before installing glass in sashes seats under them should be sanded until smooth and coated with silicone sealant.
Everything else is done as usual - the glass is installed in place and fixed with glazing beads.
If the sealant accidentally ends up on the glass, do not rush to wash it off.
Wait until the mixture dries and cures before it can be scraped off with a blade.
The last stage is fitting
All that remains is to hang the doors on the hinges and check how well they close. The latches will need to be reinstalled if necessary. Slowly run your palm along the seal (with the sash closed) to make sure there are no more drafts.
Cost of work
If you entrust window insulation in Swedish to a hired specialist, then the price of window insulation using Swedish technology for each linear meter laid insulation will cost approximately 200 rubles.About 100 rub. you will have to pay to have the glass installed on silicone.
You will also have to pay for the work of a specialist who accepts the order and goes out to take measurements (from 300 to 500 rubles).
In total, for insulating a window with dimensions of 1.7x1.4 m you will have to pay from 1.5 to 2 thousand rubles. Considering that the purchase and installation of a metal-plastic window will cost about 15 thousand rubles, the Swedish method seems quite profitable.
As we know warm air always rises to the top. This must be taken into account when organizing space heating. In order for the house to be as warm as possible and the precious warm air not to escape, you need to know.

Video on the topic
Despite the rapid growth in popularity of metal plastic windows, millions of apartments across the country are still equipped with wooden windows. It is quite natural that as they wear out and fail, not in all cases the owners prefer the expensive replacement of windows with new ones. Still in demand are renovation work related to the insulation of structures, replacement of fittings and restoration of the geometry of the sashes.
Fortunately, today there is a technology that allows not only to restore the functionality of wooden windows, but also to bring them as close as possible to metal-plastic ones in terms of heat, dust and noise insulation, protection from drafts and leaks. For this purpose it is used window repair using Swedish technology– a relatively new, but already proven effective technique.
It is precisely these services - restoration and insulation of wooden windows using Swedish technology in Moscow and the Moscow region - that are provided by specialists from the Teplo Doma company.
What is “Swedish technology”?
It is natural that homeland innovative way Window repair has become a country where issues of thermal insulation of housing play a special role. We are talking, of course, about Sweden - a country with a fairly harsh climate, comparable to northern regions Russia.
The basis of the repair in this case is the insulation of windows using Swedish technology using special seals along the entire perimeter of the sash. A special tape solves the key problem of wooden windows - airflow at the junction of glass and frame. Insufficient tightness of structures results in drafts, heat loss during the cold season, and penetration of noise and dust from the street.
Window repair using Swedish technology - simple and effective solution problems of insufficient tightness, which makes it possible to make even an old wooden window almost as reliable as a new metal-plastic one (provided that the glass is intact, the sash geometry is preserved and normal condition accessories).
How are wooden windows repaired using Swedish technology?
To understand the features and benefits this method, let us consider the sequence of actions of the master when carrying out repairs. So, how are windows repaired using Swedish technology?
- The sashes are removed from their hinges.
- Special grooves are made in the frame for installing sealing strips.
- The glass is treated with silicone sealant, onto which a sealing tape is installed.
- An inter-frame seal is installed.
- The sashes are fitted into place, adjusted and adjusted to ensure the windows open and close perfectly.
- Old fittings are being replaced with new ones - more reliable and modern.
- Locks and hinges are adjustable.
note that Swedish technology for insulating wooden windows- this is, first of all, work to improve their tightness. In the event that the appearance of the structures leaves much to be desired and/or there is damage (cracked glass, frame deformation, etc.), solving the problem should begin with traditional methods repair - replacement or restoration of failed elements.
What is a seal?
As is easy to see, window restoration using Swedish technology is based, first of all, on the use of special seals, which ensure high level the tightness of the valves.
In this capacity they are usually used tubular silicone seals, which are fixed into grooves prepared in advance by milling in the frame. Such seals are an excellent barrier against dust, dirt and drafts.
The tubular structure further increases the efficiency of the seal: a closed space with air sharply reduces heat transfer, which, in turn, reduces heat loss in winter.
The main advantages of Swedish window insulation technology
Summarizing the above, Let's highlight the key advantages of Swedish window repair technology for you, the owner of an apartment or house:
- silicone seal can be used in a wide temperature range: from -50 to +100 degrees Celsius without loss of functionality;
- a high-quality seal is distinguished by its ability to maintain elasticity over a long period of operation;
- it is very profitable to repair windows using Swedish technology: the price of new metal-plastic window systems about 10 times higher;
- the seal can be painted, it is chemically inert to dyes and atmospheric moisture;
- window restoration using Swedish technology is relatively easy to implement: windows can be insulated within one day at any time of the year, without “dirty” work and a large number of construction waste;
- Swedish technology allows you to forget about sealing windows for the winter: there is no need for this.
Insulation and repair of windows using Swedish technology in Moscow and the Moscow region is now more accessible than ever, because the services of the Teplo Doma company have many years of experience in providing services of this kind, best seals on the market, guarantee on ALL work, affordable prices and prompt order execution. Our services have already been used by thousands (and this is not an unfounded statement) of clients, whose opinions about our work you can find out from theirs.

To save money cash to replace and purchase a new window, Swedish insulation technology is becoming increasingly popular. There is a claim that after this procedure, old wooden windows can function for several more years. Moreover, the cost of all materials is affordable to almost everyone. We will try to figure out whether this is true further.
Features of Swedish window insulation
The Swedish window insulation technology gets its name from the materials used in its implementation. Rubber seals are made in Sweden, and they differ high quality and strength. According to manufacturers, this material can perform its functions for more than ten years.
The process of performing insulation using Swedish technology is quite complex, for quality work, you will need skills to work with a certain tool. Since, for example, in order for the seal to be well fixed on the surface of the window, you will need to construct a groove section, and for this you need to work with a cutter.
If you turn to the services of professionals, you will have to shell out a lot of money to carry out this process. Insulation standard window will cost approximately $20. The list of work includes:
- removing the sashes;
- preparing grooves for installing the seal;
- installation of seal;
- fitting of sashes;
- sealing glass areas.
If necessary, replacement of old fittings or repairs window box you need to spend extra money.
Tip: To save money when hiring a professional, when insulating a window with two frames, it is recommended to insulate only one of them - the inner one.
But, hiring specialists to repair and insulate windows using Swedish technology is extremely unprofitable, since the amount of repairs will be equal to the cost of a regular plastic double glazing. In this case, you will not need to waste time and effort on restoration. If you want to save money, all work must be done manually, and if you carefully study all the recommendations, then doing this is quite possible.
The window owner faces a difficult choice between buying a new window or insulating the old one. The first option will provide the opportunity to choose a new window, more modern and improved, and in the second option he will receive an old but well-renovated window. The choice, of course, remains with the owner.
If all the window parts are intact and not damaged by rot or fungus, then it is preferable to choose the Swedish insulation technology, which differs only positive reviews. If there is damage to the wood on the window, it is better to give preference to purchasing a new double-glazed window.
Window insulation using Swedish technology: features and advantages
This technology was developed by the Swedes to save energy for heating a room in winter time year. After its development, it really paid off and became quite popular all over the world.
If we compare this technology with conventional window sealing, its advantages are obvious. Since it allows for unhindered ventilation of the room even in winter.
To carry out the insulation procedure you will need:
- rubber seal;
- silicone sealant.
First, the window is removed and its sashes are dismantled. Next, using a pencil and a ruler, you need to draw out the place where the niche for the seal will be located. It is installed around the entire perimeter of the frame.
A router will be an excellent assistant for cutting out a niche. After this, a seal is inserted into it. But the work does not end there; you should check the evenness of the window, the correspondence of all corners, tighten the hinges and replace the fittings, if necessary. To seal the joints between glass and window frame Silicone sealant is used. If it gets on the glass surface, do not remove it immediately, but wait until it dries completely and use a blade to remove the frozen mixture.
Please note that Swedish seals are produced in different sizes. The selection of material is carried out in accordance with the size of the gap that needs to be sealed. The dimensions of the seal range from five to twelve millimeters.
After installing the window frame, all joints are completely sealed. In addition, it is possible to paint the window.
Advantages of window insulation using Swedish technology:
- a significant reduction in heat loss, which will have a positive effect on heating costs;
- environmental friendliness and harmlessness of the materials used do not cause allergic reactions;
- speed of the process, which lasts about 180 minutes;
- no need to constantly seal frames in the winter;
- absence of dust and dirt during operation;
- after restoration, the window will last for several more years;
- the appearance of condensation between the two panes of a wooden window is eliminated;
- the absence of drafts will improve indoor comfort and help avoid illness;
- Insulating windows using Swedish technology allows you to increase the room temperature by 3-5 degrees;
- the soundproofing properties of windows are improved - street noise and car sounds are not heard;
- the overall appearance of the window remains unchanged, the insulation is practically invisible.
Swedish technology for insulating wooden windows: general recommendations
1. Before starting all work, thoroughly wash the windows.
2. Check all window components for proper operation. Inspect the locking mechanisms and doors.
3. Remove the doors from their hinges so as not to spread dirt in the apartment or house; it is better to take them outside.
4. Adjust the sashes and remove excess paint from them.
5. Start cutting out the groove for the seal.
6. Install the seal, making sure it fits tightly to the window.
7. Draw a row insulation works on the inside and outside of window sashes.
8. Reinstall the doors.
9. Proceed to replace the fittings.
10. Check the system for drafts. To do this, bring a sheet of paper or a lit match to the window.
Do-it-yourself window insulation technology, seal characteristics
When insulating windows using Swedish technology, a tubular-shaped material called EuroStrip is used as a sealant. It is based on silicone rubber made in Sweden. This material has the following advantages:
- resistance to temperature changes;
- resistance to chemicals and paints;
- service life is more than 15 years.
We invite you to familiarize yourself with the main types of EuroStrip insulation used in the process:
1. Silicone-based sealant - has a soft and elastic texture, has good shrinkage. Resistant to alkyd or alkyd paints acrylic base. Used to seal the largest gaps.
2. The rubber-based seal is hard and rough to the touch. It seals well only in gaps of equal width. It is not resistant to paints and varnishes, and has a lower cost compared to silicone sealant.
3. Sealant in the form of thermoplastic elastomer - unstable to temperature changes, but the cheapest.
To carry out work on self-insulation Windows using Swedish technology will require:
- large construction stapler;
- milling cutter;
- silicone based sealant;
- staples for stapler;
- a roller with a handle that will help install the seal;
- screwdrivers;
- pliers;
- vacuum cleaner;
- stationery knife.
Clean the sashes from mold, paint residues or old sealant. Replace the fittings. If necessary, replace the glass. Remove the sashes from their hinges. When carrying out work in winter, take care of the installation protective screen, preventing heat loss from the room.
Using a router, cut a groove no more than half a centimeter deep and up to three millimeters wide. When you approach the areas where the hinges are located, leave a gap of one and a half centimeters between them and the groove.
Install the seal using a special roller, pumping it with this tool. When rolling, it is recommended to make return movements, which will prevent strong tension on the material and its damage.
Reinstall the sash and paint it, if necessary. Use hot glue to seal cracks in wooden areas windows.
Types of windows that can be insulated using Swedish technology
1. The windows of the pre-revolutionary period are distinguished by their splendor, large sizes, the presence of beautiful carvings and high cost. The presence of such windows in the house ennobles it, but almost all types of these windows need repair. In most cases, such windows have upper sections made in the form of an arch or a stationary frame. Their insulation involves installing a seal around the perimeter of the fragmut; if there are glasses on the putty, they are removed and installed using silicone sealant. If the fittings in the form of beautiful forged parts do not work, they have to be replaced with ordinary metal locks. Of course, with a complete restoration of windows, it is possible to manufacture fittings to order, but this procedure will be very expensive. The sashes on such sashes do not have a rebate, so the seal is installed directly around the perimeter of the frame. If necessary, seal the joints between the wall and the window, use polyurethane foam.
2. Insulating windows of the Stalin period requires caution and attentiveness. This type of window is particularly durable and of high quality. Timber was used in their manufacture best quality. The locking mechanism for such a window is a latch, which is characterized by reliable locking. They are being replaced alternative options in the form of castles. For fastening with a stack, putty made from natural drying oil and metal-containing powders was used. It is recommended to replace these glasses with more modern ones. The seal is installed around the perimeter of the box.
3. Restoration of double-glazed windows from Khrushchev times involves a collapsible structure consisting of several parts, similar to modern double-glazed windows. The seal is installed around the perimeter of the sashes, which are removed from the window one by one.
How to quickly insulate windows using Swedish technology
There is another less expensive option for insulating windows, which involves gluing a silicone seal to the surface of the sash.
Before getting acquainted with this method, we suggest considering the advantages of silicone seals over their analogues:
- low abrasion;
- good insulating qualities;
- waterproof;
- resistance to ultraviolet radiation;
- softness and elasticity;
- duration of operation;
- mold and mildew do not form on its surface;
- Can be used at temperatures from -70 to +150.
If you do not have the skills to work with a cutter or for some reason it is impossible to make a niche for the seal, there is more easy way insulation of windows. There are two variations of it:
- installing the seal using a stapler;
- fixing the seal to the surface door frame special glue;
- use of self-adhesive sealant.
All these methods are less expensive than the previous ones and help to achieve the insulation effect only for a certain time, from one to two heating seasons.
Therefore, before choosing a method of insulating windows using Swedish technology, you should weigh all the options and think about whether it’s worth doing it, or whether it’s cheaper and more practical to buy a new window.
