Window insulation using Swedish technology: pros and cons

How window frames are insulated using Swedish technology

In the construction market, a service called “window insulation using Swedish technology” is becoming increasingly popular and in demand. But some people still have doubts - does such an operation as repairing wooden frames really allow you to get a modern window, reliable and of high quality, and at the same time not pay very much, or even do the work yourself?

This type of window insulation is called “Swedish technology” because it is performed using Swedish building materials. The tubular silicone seal, made of rubber, will not be afraid of either dirt or paint. Manufacturers claim that this material can last a couple of decades.

According to experts who insulate windows using Swedish technology, it will be quite difficult to perform all the necessary operations with your own hands. You will need not only the appropriate tool, but also certain professional skills.

Not every owner will be able to use his own hands to make a cut around the perimeter of the sash with a cutter to create a groove for rolling the seal into it - such an operation is necessary so that over time the material does not peel off or fall out.

Window insulation using Swedish Euro-Strip technology, in Moscow and the Moscow region!

When insulating windows using the Swedish Euro-Strip technology, 3 stages of seal installation are used. The sashes are removed from their hinges and prepared for the correct installation of seals.

Stage 1 The Swedish Euro-Strip silicone seal is installed in the end parts of the sash. (This is the main seal that eliminates 95% of all drafts and blowing!)

Stage 2 In the interframe space (between the sashes), the Swedish EPDM seal is installed. (This is dust insulation and sound insulation) The sashes and frames are adjusted (the window geometry is restored). This helps the seals eliminate all drafts and blows, and allows you to open and close the window more comfortably!

Stage 3 At the final stage of window insulation, the glass is sealed (this is dust insulation, sound insulation and moisture insulation).

Window insulation with Swedish tubular seals can be carried out in any weather; our specialists perform the work quickly and efficiently. At the same time, our craftsmen can carry out repairs, restoration of windows, glass replacement, and installation of new fittings.

Is it expensive to repair wooden frames?

Prices for insulation and fitting of windows with standard dimensions - 1.5 * 1.2 (1.3) m - approximately 3000-3500 rubles. This includes dismantling the sashes, preparing a groove for the perimeter seal using a cutter, placing a tubular silicone seal there, if necessary, adjusting the sashes, sealing the glass to the window sash, the opening between the sashes - in cases where the sashes are paired.

Work with fittings is paid additionally - everything from repairs to replacement with new ones. Prices for them can be found when placing an order for work. If repairs to the window frame are required, this must also be paid for separately.

Important! In cases with separate type bindings, which are also called “Stalinist”, insulation is usually carried out for the internal sashes, and those on the outside are left as is. But if you order such work for external sashes, the price will be doubled.

The price lists of companies performing such work also include a painting service. Its price for a regular window will be approximately 6,000 rubles.

With such data, it is not difficult to calculate how much a full repair would cost for one ordinary window. The total cost can be compared with the cost of a standard double-glazed window.

Typically, a PVC structure of the same size, including double-glazed windows, window sills, ebb, slopes and a mosquito net, together with installation and dismantling, costs approximately 15 thousand rubles. Of course, if you decide to do all the necessary operations yourself, the costs will be completely different.

What would be better - choosing double-glazed windows or repairing old frames?

If problems with frames arise, the homeowner will have to make a choice which technology is more preferable for him. In one case, the result is a well-repaired window that closes perfectly, with seals in place, and, of course, painted. Another case is a simple turnkey plastic window. Of course, you choose the option that is closest to you yourself.

Despite the fact that the cost of both windows is almost the same, not everyone prefers double-glazed windows. There can be many reasons for this: from the personal preferences of homeowners to the reluctance to have plastic in the house. Meanwhile, reviews of Swedish technology are the most favorable.

Important! When choosing insulation for wooden windows, you should check that the frames are not rotten - replacing these elements will cost a tidy sum. First, you need to pay attention to the lower part of the sashes and window frames, where the water drains from the glass. If these elements are too rotten, restoration and subsequent thermal insulation of the window is almost pointless.

Technology for insulating wooden windows

If you decide to insulate windows in your home using Swedish technology, you should familiarize yourself with the essence of the insulation process. Some people can do the job with their own hands, but it’s better to trust the experts.

In wooden frames, a special groove is sawed on all sides. A tubular seal is embedded there, which is able to withstand temperature fluctuations from -50 to +80C. Conventional seals, which are sold in every store, will last no more than two seasons. With the use of professional materials, you will not need to worry about replacing them for 10-15 years; they do not peel off and take exactly the shape that is needed.

Repairing with a Swedish sealant is convenient because it has 5 sizes - 5, 6, 8, 10, 12 mm, which makes it possible to choose it for cracks of any thickness. In this way, complete tightness of the sashes is achieved when closing the windows.

After the seal is placed in place, both the window frame and the joints of the frames and glass are completely sealed, thereby completely eliminating possible blowing. As additional services, painting, replacement of drainage systems, glazing beads, and glass are provided. After the repair of wooden frames is completed, you get almost the same effect of double-glazed windows, but, according to reviews, with much greater advantages.

The advantages of carrying out work on the restoration of wooden frames:

The total cost of repairs is 2-3 times lower than the price of a double-glazed window.
The insulation process will not take more than 3 hours.
You don't have to seal the frames for the winter with your own hands.
All work is carried out outside the apartment, so there is no need to be afraid of spreading dirt into your home.
The frames in your apartment will continue to be made of natural material.
There will be a distance between the glasses three times greater than in double-glazed windows - due to this, heat transfer is reduced, and the appearance of condensation on the glass is eliminated.

Swedish window insulation technology

The technology, at first glance, is simple; the main condition is strict implementation of the algorithm’s points. So, the main material is a tubular sealing strip with a characteristic stripe. It is made of a unique material that is not exposed to natural conditions, chemicals, dirt and temperature changes. The service life of the insulation, according to the manufacturer's warranty, is 15-20 years.

Stage No. 1. Analysis of the condition of the window frame and its repair

First of all, the window, if it is old, must be examined for safety. The main condition is that the window must be intact. If there are rotten areas, chips and large cracks, it is recommended to replace the damaged areas.

Algorithm for diagnosing the window state:

visually inspect the external condition of the frame;

Important! Pay special attention to the safety of the bottom frame bar - this is the place where condensate concentrates during operation.

if damage is found, then the wood must be treated with putty and a layer of paint applied - this will stop rotting and strengthen the structure;
inspect the hinges: they should not sag, but should be in good working order. If the hinges are faulty, they must be replaced;
check that the windows close tightly. Are there any gaps or distortions?
We check the condition of the glass; if there are cracks or chips, we replace them with new ones.
We check the quality of the fittings: latches, locks. To achieve complete sealing, the window must close easily and tightly.

If the window has no defects or you have corrected them, then you can proceed to the next step.

Stage No. 2. Sealing glass

We take measurements of the window and calculate the required footage of the seal. Next, we proceed to check the location of the window and the quality of the clamp. We eliminate the gaps between the glass and the frame. To do this, you need to remove the glass and treat the joints with sealant. Then install them back and secure them with glazing beads. Sealing the glass joint will enhance the insulation effect.

Attention! Any work on frames is carried out subject to their cleanliness, that is, the windows must first be cleaned of dirt, paint residues and the surface degreased.

Stage No. 3.Marking

We make markings for the groove along the perimeter of the frames. To do this, we use a level so that the line is even, it is necessary to take into account that the seal should not break or be pinched by the sashes.

After marking, we proceed to cutting the groove.

Important! Cut the groove clearly along the marked straight line, since the durability and high-quality operation of the structure depend on the quality of installation.

This process is carried out using a special tool - a cutter. For installation, you need to remove the window sashes and carry out the work on the table - this will greatly facilitate the process.

The groove angle should be 45 degrees. Before installing the tubular seal, it is necessary to clean the surface of the window and the groove from shavings and sawdust.

Stage No. 4. Installation

The rope is installed using the pressing method - this is the main condition of the technology. It is carried out using a special tool - a roller. Using a roller, the seal is pressed into the groove.

Important! When insulating windows using Swedish technology, no glue, sealant or other fastening methods are used.

How is window insulation performed using Swedish technology?

Insulating windows using Swedish technology allows you to restore old frames and extend their service life. At the same time, the appearance is improved, functionality and tightness are increased, and the design better protects from cold and wind.

Thanks to these features, it is not necessary to dismantle wooden frames for replacement. It is recommended to first compare the cost of updating an existing structure and purchasing a metal-plastic window. The complexity of implementing the technology is also taken into account.

Do-it-yourself window insulation using Swedish technology

Procedure in the form of step-by-step instructions.

Stage 1 – window check

Before you begin insulation, you need to carefully inspect the windows, namely, pay attention to:

casement windows. Checked for defects, cracks, chips, etc.;

window frame. In particular, its lower elements (water flowing from the glass first of all destroys the bottom of the window frame);

places where loops are inserted. The wood in these areas wears out over time. You need to make sure that the frame is in good condition, then the hinge will securely hold the sash, preventing it from sagging.

If the wood and fittings are in good condition, you can start working. Otherwise, partial replacement of damaged frame elements may be required, and in critical cases, replacement of the entire window unit.

Stage 2 – purchase of material

Swedish insulation involves the use of a special material - EuroStrip sealant. You can use similar seals, but only Eurostrip has a 20-year warranty. Domestic material can withstand from 1 to 5 years of operation. Considering the labor intensity of Swedish technology, replacing the seal with an analogue does not make sense.

Types of EuroStrip seal:

thermoplastic elastomer (TEP) . Diameter 6-8 mm, roll length 100 m.p. The cheapest of this series. Destroyed under the influence of temperature changes;

rubber (EPDM) . Made from rubber based on a copolymer of ethylene, propylene and diene monomer. Diameter 6, 8, 10 mm, roll length 200, 150, 100 m.p. respectively. More expensive than the previous one, but rigid, it can be easily placed only in a perfectly prepared groove. Susceptible to paint.

silicone _ Made from silicone rubber. Features a tubular profile and herringbone fasteners. Diameter 5, 8, 10, 12 mm. Roll length 100 m.p. The most expensive representative of the series (25 rubles/m.p.). The EuroStrip silicone seal has characteristics that justify its cost and make it popular among users. Therefore, experts recommend using it.

Groove seal for wooden windows

Advantages of EuroStrip silicone seal:

softness;
elasticity;
resistance to aging and ultraviolet radiation;
insensitivity to paint;
wide range of operating temperatures (from +80 °C to -50 °C) and resistance to temperature changes;
lack of linear changes;
rapid restoration of the original shape.
stretches without tearing (this characteristic allows it to be used in an unevenly cut groove);
service life 20 years.

Marking on the seal:

E – tubular profile, for minor gaps: 2-3.5 mm;
P – for medium-sized gaps: 3-5 mm;
D – for wide gaps: 3-12 mm.

Note. The size of the gap is determined by plasticine, which is wrapped in film. The plasticine is clamped between the sash and the frame, and the depth of the groove is estimated from the resulting ridge.

Tools for insulating windows using Swedish technology: a milling cutter (a straight grinder at a speed of 300 rpm), a roller for placing the seal in the groove, a screwdriver, pliers, a construction knife, a vacuum cleaner.

Stage 3 – repair of wooden windows using Swedish technology

remove the sash from its hinges. The places where the sash is pressed tightly against the frame need to be trimmed; if there is a significant gap, increase the strip to the required thickness;

open the window, check the quality of the wood of the frame and sashes, evaluate the quality of opening;

clean the sash from paint and dust;

Preparing windows for insulation using Swedish technology

select a groove around the perimeter of the sash. The cross-section of the groove is 3x5 or 3x7 mm. Thanks to the herringbone fastener, the seal fits well into the groove and holds securely in it. This ensures that during the period of operation the seal will not come out of its seat.

How to make a groove in a window frame for EuroStrip sealing for insulation using Swedish technology

In the place where the hinges will be on the sash, the seal is not installed. When forming a groove, a gap of 10-15 mm is left between it and the plane of the loop.

Note. In the case of insulation of “Stalinist” windows (which open separately), the seal is placed only along the internal contour. Otherwise, the glass of the outer doors will fog up.

filling the seal into the prepared groove. Easier entry of the seal into the groove will be ensured by the use of a roller.

How to insert a groove seal into a window frame seat

Recommendation. The roller must not move forward; this can lead to stretching of the seal. It needs to be rolled in a “backwards” motion, placing it in a groove of 30-50 mm. seal.

the prepared sash is installed in place.
the seat is treated with transparent silicone sealant;
the glazing beads are removed, and the installation site of the window in the sash is cleaned;
the beads are installed in place; Material prepared for the website www.moydomik.net
The operation of the window and the tight fit of the sashes to the frame are checked.

Note. Swedish window repair technology involves replacing old hinges, screws, latches, glazing beads and other window fittings.

Please note that after insulation using Swedish technology, the windows will become airtight, as a result, this may lead to poor ventilation in the room. A forced ventilation device and periodic airing eliminate this circumstance.

Note. The heat-saving properties of the window can be increased by additional finishing of the slopes.

Advantages and disadvantages of the technique

The effectiveness of insulation using this method is due to the fact that a seal made of rubber is added to the design and is characterized by excellent performance in reducing heat loss in the room. This is Swedish material, hence the name of the technique. It is mounted in a special way, which makes it more difficult to carry out repairs yourself.

Swedish window insulation technology is popular due to a number of positive qualities:

The seal lasts a long time - about 20 years. For comparison: foam rubber and simple rubber require replacement after several seasons of use.
Swedish material does not accumulate pollution.
Tightness. The seal does not allow wind to pass through and significantly reduces heat loss.
Thermal and sound insulation properties are improved.
By reducing the intensity of heat outflow, heating costs are reduced.
Time saving and practicality due to the absence of the need to repeat the procedure annually.
The seal can withstand significant temperature fluctuations: from -50°C to +80°C,
Creating a barrier to dust and other contaminants that often penetrate from the street into the room.
Improving the appearance of the window frame and sashes, because Before installing the Swedish sealant, the wood is restored.
There is no need for additional window insulation.
Reduces the risk of condensation.
The window frame retains the ability to “breathe”.

If we compare the Swedish method with the Finnish one, there is another advantage: it is not necessary to install insulation on all sashes (only on the internal ones), because The window is a prefabricated structure (double sashes are twisted together).

There are also disadvantages to this method. If you plan to use Swedish technology for insulating wooden windows with your own hands, you may encounter difficulties. We are talking about the need to use special equipment. So, to install the rubber seal, you need to make a groove around the perimeter of the sashes. The material will be placed in it.

Another disadvantage is the relatively high cost of performing the work. In addition, if you make mistakes during installation or use low-quality material, the service life will be shortened, and the sound and heat insulation properties will be weakened.

For this reason, it is recommended to use the Swedish method in two cases:

it is not possible to dismantle the window and replace it with a metal-plastic one;
there is confidence in the professionalism of the worker who will restore the window frame.

Necessary tools and cost of consumables

To restore old wooden windows, use the following set of tools:

roller walker, through which the rubber seal is placed in the grooves;
screwdriver;
milling tool - it is used to make grooves.

The cost of the material depends on its type and cross-section configuration. Available options:

thermoplastic elastomer, or TPE, costs less than its analogues (from 11 rubles/linear meter and more), because does not last long due to exposure to temperature changes;
rubber material is made from rubber and represents an average price category;
silicone rubber - a material for sealing windows, representing a high price category (25 rubles / linear meter) - is distinguished by a convenient cross-sectional shape (round with a herringbone fastening) and is characterized by elasticity.

In order for the structure to serve for a long time, it is not recommended to choose cheap material. The best option for insulation using Swedish technology is a silicone seal.

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. When in contact with paint and varnish materials, unlike silicone EuroStrip, it 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.

Stages of work

To repair wooden windows, you should first select insulation. It differs in cross-section configuration:

W-shaped;
P-shaped;
V-shaped;
round;
in the form of a semicircle;
tubular material with internal fins.

The diameter of the Swedish seal also differs. The market offers a large number of options, but the material is selected taking into account the size of the leaks in the frame: 2-12 mm. When the sealant has been selected, we proceed to window repair using Swedish technology:

Preparatory stage. Restoration can be carried out provided that the window unit is suitable for the work. Check the condition of the lower part of the frame. Also, there should be no obvious defects or large cracks on the sashes.

The area of wood where the hinges are installed is also examined. The material gradually wears out, which can lead to sagging of the sashes. If there are defects, they are eliminated using putty and the painting method. Worn out structural elements are replaced.

Before insulating wooden windows using Swedish technology, it is recommended to dismantle the main structural elements and carry out restoration. The sashes are removed from the awnings. Frame removal may be required.

If necessary, the glass is also removed. All elements of the window block are cleaned of old coating and defects are eliminated. If during the inspection phase it is discovered that there are still leaks when closing, grinding may be required. If the gap is significant, the surface is increased using a lath.

Window insulation using Swedish technology is performed after preparing the groove for the rubber seal. It needs to be done around the perimeter of the sash at an angle of 45°. Moreover, it is important to immediately remove the chips and further clean them. Groove dimensions: 3x5 mm or 3x7 mm.

A Swedish seal is placed inside. If a silicone product is used, it has a herringbone-shaped mount. This makes it possible to fit the material tightly into the groove. A special tool is used.

If you plan to insulate windows using Swedish technology yourself, you should know that it is necessary to eliminate all sources of draft. This means that, along with installing the silicone material around the perimeter of the sash, sealant is applied to the areas where the wood and glass join.

Where the hinges are installed, no seal is installed. Here it is recommended to make a small indent from the hinge area (10-15 mm).

After laying the seal, the sash is returned to its place.

If you plan to insulate windows using Swedish technology, then gluing silicone material to the sash is not recommended. At the same time, it loses its elasticity. In addition, in cases where the moving elements of the window unit are opened separately, the seal is secured only from the inside.

You should know that the Swedish repair method is also suitable for thermal insulation of plastic windows.

Silicone method

The method using silicone involves similar work, but there is a significant difference in that the seal is laid on the cleaned frame using a silicone-type sealant.

So, the reviews for repairing wooden windows using Swedish technology are unanimous - this technology allows you to effectively deal with drafts, and also protects the house from dust and foreign odors. In addition, windows made using Swedish technology have the highest level of thermal insulation, as well as an appropriate level of sound insulation.

And now we offer what we have gathered for! Before you repair reviews:

Anton Ordered a 2-fold door - surprisingly they did it quickly and even without unnecessary debris. I have been living in comfort and warmth for two winters now.

Anna Thank you very much master. Nothing is blowing, there is no draft, the house is warm and now there are even no sounds that usually come from the street. Even though we live in the center of Moscow.

Katya We insulated the simplest window using the Swedish method. The result was quite satisfactory, master Evgeniy did the job conscientiously, and he is a very polite person. Thanks a lot!

Mikhail So I’ll write a review. Before I decided to insulate for a long time, I spent a long time looking for repairs of wooden windows using Swedish technology, reviews, and only then ordered this particular insulation. Before this, I tried many times to make wooden windows warm with my own hands. This didn’t really help since we live in a cold hemisphere and it was always cold at home. When the master arrived to insulate the window, the sash swelled very much. Within 3 hours the job was done – I’m happy! Firstly, the draft was completely eliminated, secondly, it simply became warmer, and thirdly, the cost of the insulation work was also pleasing. The private owner was chosen on the advice of friends.

Clara All the reviews that I read about the Swedish technology inspired me and I decided to make the window insulation myself using this method. In general, our house is cold and there is always something called a stream of air. Of course, I live with my husband and he is my foreman, but even he couldn’t come up with anything better than sealing cracks in the windows with adhesive tape and newspapers. But the result, to put it mildly, did not suit us - after all, there is a small child in the house and drafts can be dangerous. Master Alexander arrived and did the job in two hours. A very nice guy too. Now our windows are insulated and there is not only no draft, but not even any sound from the street. The heat in a private home lasts for a long time! Repairing wooden windows using Swedish technology, I also read reviews and came to the conclusion that I need to order just such insulation. Prices. Basically, they are the same in Omsk companies, but we found the most affordable option. I recommend this technology to everyone. You will be satisfied!

Dmitry Last year we installed plastic windows. I thought we’d be content, but that wasn’t the case – the constant unpleasant smell is something. It is felt especially strongly when the plastic begins to be exposed to direct sunlight. We have a nine-story building and the windows face the sunny side. There was such a smell in the summer that it was simply unreal to be in the room. I started talking to friends and they suggested that there are plastic windows that don’t smell. I have already decided to save up for them because what alternative could there be? No. Then I learned that odorless plastic windows are practically not supplied to Russia. A builder I know said that in Europe there is now an ecology boom and they use wooden windows there. I was very surprised, but that’s not the point. My builder said that the main thing is that it is wood, and whether it is old or not is the tenth question because even old wood can be restored so that the window will be better and more functional than any plastic one. It's good that I didn't throw away the old wooden windows. I started looking through my friends for craftsmen who restore wooden windows. Then I began to study the reviews of repairing wooden windows using Swedish technology. Everything was confused in my head. In the end, I finally found a restorer and set the condition that I would pay if they not only did external repairs, but also replaced all the window fittings on my old window. We also had to install a new door closer and other small components. Next came cleaning - as a result, the old wooden window opened no worse than the new plastic one, the sashes work perfectly. Of course, it didn’t work out to put all the cool bells and whistles of a plastic window on a wooden one, but the appearance of my window became unrecognizable in the good sense of the word. Especially after painting the frame. As it turned out later, the window was insulated using the above-mentioned Swedish technology and now it’s cool in the summer and literally hot in the winter. Now I want to buy completely new wooden windows eventually. I recommend insulation using Swedish technology to everyone!

Masha We insulated old wooden windows using Swedish technology about 6 years ago. We read the reviews for a long time before deciding. Today the house is very warm in winter; there are simply no drafts like before. I am satisfied and recommend this technology to everyone who has old wooden windows.

Zina We decided to insulate the windows in the summer so that winter wouldn’t take us by surprise. We chose from a bunch of private owners. Then we decided that we would contact the company. I wanted to find an experienced craftsman and only one who would deal exclusively with window insulation. I chose in Yandex. I thought this - if they do something else besides insulation, then they don’t have time to do the first thing. A bunch of companies fell off this way at the very beginning. I called all the remaining companies, which is about 5. I wanted to choose a more experienced specialist. Only one call was answered by a confident male voice - and I chose him. Yes, in other companies it was not children who answered, but this voice seemed wise to me. Master Anton arrived quickly and completed the insulation in less than half a day. I was pleased with the result - now even in winter our house is warm and there is no wind from the street at all.

Nikita We recently insulated the windows using Swedish technology. It’s very cold in our apartment, and we didn’t want to install smelly PVC sheeting because we had heard a lot about its smell. We chose a private owner through Avito - he came and insulated the balcony window and single-leaf window. We chose the specialist with the lowest price. In principle, everything suits me. Warm.

Vladimir I have long wanted to change the windows for my parents, but they are people of the old generation and for a long time refused plastic windows. In the end, I gave them up too. We started looking for something to replace them with; repairing wooden windows using Swedish technology also read reviews and came to the conclusion that insulation is the way out. The main thing is that parents do not have to seal them and wash them in winter and spring. It's been 4 months since the insulation has been done and the house is warm despite -30 outside the window. I definitely recommend this technology. They did all the work for us in just two hours and also installed new fittings.

Inga We've been taping up windows all our lives, but at one point I got tired of it. I started reading the Internet and realized that you can simply insulate a wooden window – once and for all. I decided to take a risk. Two craftsmen arrived and did the work quickly and efficiently. The main thing is that after two years the house is still warm in winter and there are no drafts.

Andrey About a year ago I read reviews about repairing wooden windows using Swedish technology and thought for a long time whether it was worth it. As a result, the windows were insulated using this technology. At first I thought there would be no draft, but the result in the end exceeded all expectations. I was pleased that the master did the work conscientiously - some parts did not fit into the old wooden frame and he carefully processed it. After installation, as I already said, the blowing stopped, the window opens and closes easily - even better than PVC. Apart from this, there is simply no noise from the street in the apartment at all. And this is in comparison with the plastic that we decided to install in the kitchen. Then I didn’t like that, how can I put it, the sellers simply sell the window, but do not service it. And now, a year later, the plastic window is noticeably blowing, and the shutter has simply begun to play a lot. Now in one room we have a plastic window, and in the other the window is insulated using Swedish technology. We will monitor which of them will live longer, but it is already clear that the tree turned out to be much more durable and of better quality.

Vyacheslav Installed a PVC window for my granny - she didn’t like it mainly because of the smell of plastic. The old wooden window was returned. I was looking for repairs of wooden windows using Swedish technology for reviews and found many positive ones. We installed an old window and insulated it - my grandmother couldn’t be happier and I’m happy - the house is cool in the summer and very warm in the winter. In addition, the master corrected the perimeter of the window and now there are no gaps.

Denis When I was looking for reviews about window insulation using Swedish technology, I found only those where they wrote how they were installed. I wanted to insulate my wooden window with my own hands. Unfortunately, I couldn’t find detailed instructions or the Swedish method anywhere - I decided to do it by instinct. As a result, the window was adjusted and did not even close completely. The wind remained the same, the window was loose and remained that way after my repair. I bought so much material that, as the master later explained to me, it would be enough for 2 years of work. After my insulation, the window did not look very presentable - nails were sticking out, and the frame was deformed. But the worst thing is that the new insulation simply came out after about 5 days. I insulated one window for about a week and in the end my wife couldn’t stand it and called the contractor. When I saw with my own eyes how quickly and efficiently he insulated the window using Swedish technology, I realized that everyone should mind their own business. It was even awkward to show them the results of my activities. As a result, the master fixed it and now the window is clean, beautiful and well-groomed. And most importantly, even in winter there is no draft, which has plagued us for many years. I spent half as much money on the work as when I tried to insulate the window myself.

Volodya I am a professional craftsman and have been restoring windows using Swedish technology for about 10 years. Most often they order this kind of insulation when it comes to wooden windows. I can note the durability of such insulation and the well-functioning technology in general.

Sveta It’s winter again and we’re tired of the draft in our house. I went online and found tips on how to insulate using tape and cotton wool, but after a week this improvised insulation simply flew out. It blew strongly, although there were no cracks or holes in the wooden window. I had to go online again. This time I found a list of private owners who insulate the window using tape. I called. Had arrived. Did. It doesn't seem to be blowing. The yellow tape holds well, but it is forbidden to open the windows - the tape comes off easily, but it will not be possible to put it back in place. Yes, and gluing a new one every time is also not an option. I went to Yandex and typed in reviews for repairing wooden windows using Swedish technology. I found a few reviews, but almost all of them were positive and that made me happy. I called a dozen companies. In the end, I chose simple guys - I don’t like it when they show off too much. Two guys arrived and started removing the old window. I had to put on a jacket because it was winter outside and it was very cold. Within 4 hours the window was put in place. During this time, handles, slopes, hinges were installed and the window was well ventilated. They didn’t paint it, at first it seemed to me that nothing had changed, but the very next morning I felt that the usual draft was gone. I am very grateful to the masters - now our place is warm and cozy. Another important plus is that the noise from the street also disappeared.

Ivan Insulating old wooden windows using the Swedish method is really effective and significantly reduces heat losses. I didn’t want to spend money on installing plastic windows, and everyone says that wooden windows are better. That is why I decided that I would insulate it. I found a private contractor who insulated a double-hung window in two hours. I am pleased with the result as the apartment is now very warm. There are also no complaints about the operation of the fittings.

Kolyan It’s cheaper to replace wood with plastic, but my wife and I decided to insulate existing windows. We called a bunch of companies - in some places the cost was too high, and in others it was quite acceptable. We didn’t want to wait until next winter, so we started restoring the windows in the house in the summer. We immediately decided to insulate it using Swedish technology; all my wife’s friends praised it and she didn’t want to hear about anything else. The master we found in the company assured us that this technology can significantly reduce heat loss. We were happy with the cost of the work and decided to conclude a contract. The work began the very next day - as a result, all the windows in the apartment were insulated and we were satisfied. Even at -25 in our house it is warm and even hot.

Matilda I read for a long time the repair of wooden windows using Swedish technology, reviews in Yandex. And I decided to make such insulation myself. The Moscow Windows company sent a master who, within three hours, updated and completely insulated my windows. I paid little, taking into account the discount, and am very pleased with the result. Now I boast to my guests about my warm wooden windows and have always scolded plastic for its terrible smell.

At the end, we offer a video about do-it-yourself window insulation using Swedish technology:

How much will it cost to insulate windows using Swedish technology when you call a specialist to your home?

First, the cost of materials that will be used in the process of restoration of the valves is calculated. If it is not possible to use the necessary tools, a specialist is invited. The cost of repairing wooden window frames is calculated separately.

The degree of complexity and scale of the work should be taken into account. The average price is 100 rubles/linear meter. Directly laying Swedish insulation in the grooves costs more - 200 rubles / linear meter.

In addition, a fee may be charged for filling out and processing the application, as well as the initial call to the specialist and consultation (300-500 rubles). The announced prices are not final, because may vary depending on which repair company you contact. The cost of restoring a large window using this technology corresponds to the price of a plastic window block from the middle price category. However, wooden structures look more attractive.

Features of the technology

Swedish window insulation allows you to get a modern, reliable and high-quality window from an old structure. At the same time, the costs of this procedure are minimal, especially if the work is done independently.

This type of insulation is called “Swedish technology” because it was invented by thrifty Swedes for the purpose of energy saving. In addition, insulation is carried out using Swedish building materials, in particular Swedish silicone sealant.

This material can withstand temperatures from -50 to +80 degrees Celsius, while being able to take any shape and maintain elasticity. According to manufacturers, such a seal will last a couple of decades, while conventional insulation needs to be changed after two or three seasons.

Unlike the traditional and thorough sealing of windows, insulation in this way will allow you to open and close windows without hindrance throughout the year. However, it should be said right away that Swedish insulation is a relatively complex procedure that requires certain skills and the availability of the necessary tools.

In particular, not every home craftsman will be able to make a cut around the perimeter of the sash with a milling cutter in order to obtain a groove for rolling the seal there. And without performing this operation, the material can quickly peel off and fall out. Also, insulation involves replacing all fittings so that the structure functions as expected.

Therefore, if you are not confident in your abilities, then it is better to entrust this work to qualified specialists. The price for their services will be justified by the quality of the insulation and the guarantee for the work done.

Swedish insulation or double glazing

Often, homeowners are faced with a choice - to insulate a window using Swedish technology or install a new double-glazed window. In the first case, you will get a wooden window that is well sealed and opens and closes perfectly in winter and summer. In the second case, a turnkey plastic window will be installed.

Many people prefer wooden windows, and not only for reasons of economy. The fact is that wood is a more environmentally friendly material; its ability to “breathe” provides a favorable indoor microclimate. In addition, this technology receives the most positive reviews from the owners of such windows.

Note! Before making a choice in favor of insulating windows, you need to make sure that the frames are not rotten, since replacing these elements will cost a decent amount, so insulating them will be pointless.

Insulation technology

Window repair

So, the instructions for performing repairs and insulation are as follows:

First of all, you need to dismantle all the fittings - hinges, locks, latches, etc.
Then the structure must be cleaned of old paint. The easiest way is to use a hair dryer and a scraper. You can also remove the old coating using a special chemical solution called a stripper.
After this, the structure should be treated with a primer composition, which will have an antiseptic effect and also improve adhesion between the wood and the new paintwork.
Then the most complex procedure is performed - a groove is selected along the perimeter of the wooden frames, in which the seal is subsequently fixed.
Next, the wooden structure is painted. To do this, you can use a spray bottle or spray bottle.
After the paint layer has dried, a sealant is glued into the grooves. Due to the fact that it has 5 sizes, you can choose the right material for any cracks. This allows you to achieve complete tightness when closing the doors.
Next, you need to completely seal the window frame, as well as the joints of the frames and glass. To do this, it is best to use silicone sealant.
Then the installation and adjustment of hinges, latches, etc. is carried out.

Advice! If sealant gets on the glass during work, you need to wait until it dries, after which you can scrape it off with a knife.

As a result, Swedish window insulation technology creates the same double-glazed window effect, but with even greater advantages than metal-plastic windows.

Executing the slope

To achieve the maximum effect from window repairs, it is necessary to pay attention to the insulation of slopes.

The window opening can be finished with the following materials:

Plasterboard;
Plastic;
Sandwich panels.

The installation technology for all these materials is very similar and looks like this:

First of all, the old coating is removed, especially if it is crumbling and falling off.
Then the window opening must be treated with an antiseptic that will prevent the occurrence of fungus and mold. (See also the article How to cover a window with siding: features.)
Next, starting profiles are mounted around the perimeter of the frame. Before fixing them with self-tapping screws, you need to check the position with a building level.
After this, panels for slopes of the required size are cut from sheets of plasterboard or plastic, taking into account the layout.
Then, thermal insulation material is placed in the space between the wall and the slope. As a rule, mineral wool is used for these purposes.
Next, the cut slopes are inserted with one edge into the starting profile, and attached to the wall with the other. For these purposes, you can also use a special profile or glue. Drywall is usually glued with gypsum mortar.
After this, the corners are trimmed using plastic or metal profiles.
If plasterboard is chosen as the material for the slopes, then it needs further puttying and painting. (See also the article Painting the facade: features.)

Advice! If, after insulating the window frames using the Swedish method, the windows begin to fog up, then it is necessary to provide ventilation in the room.

This phenomenon occurs due to disruption of natural ventilation through cracks.

How is window insulation done using Swedish technology?

The process may seem complicated to an amateur, but it takes very little time for a professional.

The technician checks that the window is evenly seated; if the sashes are crooked somewhere, they are adjusted with a jigsaw or the hinges are tightened. Everything must be aligned perfectly.

Then a groove is cut inside along the perimeter into which the EuroStrip material is pressed. Thus, the window is insulated, and only a white strip remains outside - smooth and neat.
