Insulation using Swedish technology for wooden windows and doors. How to insulate windows using Swedish technology - step-by-step instructions Windows using Swedish technology from a company

Insulation wooden windows using Swedish technology - this is a reliable modern method that allows you to insulate any window. Giving it high heat and sound insulation characteristics. The technology was first used in Sweden, in Russia it has been around for about 15 years and has managed to prove itself in our winter conditions. The main secret is the unique EvroStrip silicone tubular seal.

Swedish silicone EuroStrip seal remains elastic in the temperature range from -50 to +100 degrees Celsius.

Unique seal

The EuroStrip seal is made of silicone rubber, due to which it has unique characteristics. The temperature range of the seal is from -50 to +100 degrees Celsius. The seal does not harden in the cold and does not deform when heated. Not afraid of paints and solvents, does not absorb dust and debris. The seal manufacturer guarantees the wear resistance of the material for 10 years. Swedish technology is ideal for the climatic conditions in our country.

A special groove is made for the seal along the entire perimeter of the sash. The seal is fixed mechanically; the lower part of the seal in the shape of a herringbone is rolled into the manufactured groove. The manufacturer produces seals of various diameters from 5 mm to 12 mm, which allows you to close any gap; due to its tubular shape, the seal takes any shape, filling the space between the frame and the sash.

Sealing and adjustment

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 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 install glass on 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:

1. 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.
2. 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.
3. After the upgrade, the window will no longer fog up from the inside.
4. Only environmentally friendly materials are used.
5. For all its effectiveness this method requires purely symbolic costs that even a pensioner can afford.
6. With minimal skills in working with some tools, window insulation using Swedish technology can be done on your own.
7. You will need to spend no more than 3 hours on everything.
8. 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 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. Special attention should be turned onto 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 the old paint on the window has peeled off, it must be removed and the entire structure repainted. WITH wooden surfaces The paintwork is very easy to remove using 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 metal product will not work.

Before applying fresh paint, window elements are treated sandpaper(first large, then small) 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 the end surface of the sash and the strip on it, which, when closed, is adjacent to the frame (it covers the gap between the frame and the closed sash). In this case, the cross-sectional axis of 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 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

Insulation of wooden windows in Moscow and the Moscow region has been our main specialization since 1993!

We insulate all types of wooden windows - both with double-glazed windows (information about this is in the section on insulating wooden windows with double-glazed windows and in the section on repairing plastic and wooden windows), and insulating ordinary wooden windows.

For wooden frames from the Soviet period, we primarily offer modern grooved version of window insulation using Swedish technology EUROSTRIP.

The Swedish window insulation technology EUROSTRIP got its name from its name trademark EUROSTRIP, manufacturer of used seals.

EUROSTRIP is a trademark of the Swedish concern TRELLEBORG, which produces various types rubber products, including household seals for windows and doors.

The manufacturer's website www.trelleborg.ru contains information about seal materials, their characteristics, as well as dealers in different regions RF.

All the seals we use for insulating ordinary wooden windows are stamped - that is, on the seal itself there is a marking that informs about the country of production (Sweden), the manufacturer's trademark (EUROSTRIPE) and the composition of the material (SILICON, EPDM, TPE).

With this option of insulating windows along the perimeter of the sash or, if this is not possible, then along the perimeter of the frame at the junction of the sash and window box the mounting groove is milled. The groove is about 3 mm wide and about 8 mm deep. (As a rule, to perform this work, the sashes are removed from their hinges). It is necessary to use a router, not a grinder, and a cutter required diameter, because when drilling a groove in other ways, for example, when using an angle grinder (grinder), it is not possible to maintain the required cutting width. This means the seal will not stay in the groove correctly and will fall out. Savings on purchase necessary equipment will result in irreparable defects.

An original stamped seal of the EUROSTRIP brand made of silicone rubber is rolled into the milled groove. We only use silicone rubber because it has improved performance characteristics compared to regular rubber (EPDM).

Firstly, due to its chemical inertness, silicone sealant is not afraid of contact with almost all types of paints, in particular alkyd, acrylic and aqua enamels. After drying, the paint that gets on the silicone seal forms a film that gradually peels off. In this case, the seal remains undamaged. You just need to carefully clean it of dried paint (it is best to do this a few weeks after painting).

For comparison, a seal made of ordinary rubber (EPDM) after contact with even a small amount of paint hardens or melts and must be replaced. A sealant made of thermoplastic elastomer (TEP) or thermoplastic elastomer (TPE) is even more capricious when exposed to paints - it practically dissolves and turns into a porridge-like mass.

Secondly, the silicone seal is very elastic. But this is one of the most important properties sealant used for insulating windows. After all, an inelastic seal will not provide a tight seal when the surface is uneven. In addition, over time, a natural increase in the gap gap occurs (the frame has dried out, the fittings have worn out). The silicone seal, due to its elasticity, will close the enlarged gap. And the EPDM grade sealant will remain deformed, flattened, inelastic and “will not fit behind the gap.”

Thirdly, silicone sealant is more durable than EPDM and TPE sealants and has a much wider temperature range of use, which means it is best suited for insulating windows for the winter.

For these reasons, EPDM and TPE sealants are not recommended for insulating wooden windows of the Soviet period. And the silicone seal is the most best option for insulating old windows.

When ordering work from us to insulate windows using Swedish technology, the price already includes, if necessary, fitting and adjustment work (so that the window opens and closes normally), sealing the joint between glass and wood with silicone sealant and an inter-frame anti-dust seal (for frames screwed together with screws).

The warranty period for insulating wooden windows using the groove method is 3 years. Service life 10-15 years.

By insulating a window, you only change functional characteristics windows - ease of opening and closing, heat-insulating and noise-insulating properties.

And to change the appearance of the window, painting of the windows is required; with this type of insulation, it can be ordered simultaneously with insulation or separately, at any time later, since we use silicone seals that are not afraid of paints.

Also we have cheaper homemade options for window insulation- self-adhesive rubber seals, usually also from the Swedish company VARNAMO, or polyurethane foam or polyethylene foam seals. And also completely inexpensive options insulating windows as in ancient times - with cotton wool, paper, masking tape.

Prices for insulating ordinary wooden windows in Moscow and the Moscow region using the groove method:

insulation of medium-sized sash (up to m2) for paired windows - 2000 rub.

insulation balcony door for paired windows - 3000 rub.

For handicraft options - from 1000 rubles to 1500 rubles per sash up to m2.

As for artisanal options, “grandmother’s” methods, they are usually intended for insulating very old windows, which you don’t mind spoiling, and the service life of such artisanal methods is very short, as a rule, it is one season, that is, no more than 3-4 months.

Let's take a look at some of these artisanal options. And at the same time we will trace the history of the issue.

- Putty- this method of insulation has been around for over a hundred years. Insulation in this case consists of coating the glass at the junction of the glass and the frame, if the glass is fastened without glazing beads, simply with nails, that is, we are talking about very old, pre-revolutionary windows, which are almost non-existent in the Moscow region, or in coating the junction of the frame with the glass in front by nailing a glazing bead if the windows already have glazing beads, that is, for windows manufactured after 1917-20 and before about 1995. This method became completely and irrevocably obsolete with the invention of window sealants. Around 1985-90, sealants replaced window putty. Sealants are applied to the window in 1-2 minutes, and window putty 1-2 hours, and they do not need to be hidden under glazing beads, since they themselves are quite aesthetic - white or transparent strips next to the glass perform all the functions of window putty, but last much longer . But the window putty is brown and spreads from the heat and forms smudges and needs to be hidden under the glazing bead, and in order to apply window putty under the glazing beads, you need to remove the glazing beads, which can crack the glass. In general, even our grandmothers have long forgotten about window putty.

- Paraffin. The candle wax is melted and all the cracks are covered with it like plasticine. It’s a little easier to wipe off than window putty, but it also takes a long time, and you’ll have to spend a lot of time melting the wax and applying it while it’s still hot. Recommended only in hopeless situations- for example, a hut in the taiga, cut off from the world by permafrost, and there is a supply of candles.

- Hemp sealing rope- was used for partial sealing of the joint between the sash and the frame and insulation of windows in the pre-revolutionary period and until approximately the 1980s of the last century. The rope was nailed along the perimeter of the sash. There was an insulation effect, but it was far from complete; the gaps still remained, but without the ropes the blow would still have been even stronger. After the next painting, the ropes hardened and were no longer useful, they only interfered with the normal closing of the windows. After about 1985, ropes were replaced by foam rubber seals and then self-adhesive polyethylene foam seals.

- Old newspapers- used to insulate windows also in the last century. They were used in two ways: either rolled and lightly soaked and stuffed into the gap in the narthex, at the junction of the sash and frame; after drying, the newspapers swelled and filled the space, or cut into strips and pasted onto the junction of the sash and frame soapy water, milk or starch or wallpaper glue. Or at the same time both for filling the gap and for pasting over the false gap. The disadvantage was that the method was one-time, that is, after opening the window, all the insulation had to be started all over again, and in addition, the newspapers stuck to the paintwork and the windows had to be repainted in the spring. Therefore, in those days, windows were painted almost every year. The method became obsolete with the advent of self-adhesive seals, that is, approximately in 1985-1995. IN Soviet time was very popular. Enterprises usually held cleanup days and employees themselves insulated the windows using this method.

- Old rags, cotton ones are best. They used it in much the same way as newspapers. And around the same time. They cut it into strips and glued it around the perimeter of the sash when closed. Under the strips of paper, an additional seal was usually placed in the cracks from old newspapers, and later from cotton wool, and then, after the 1970s, even from foam rubber. The disadvantages are the same - fragility, no more than one season, and damage paint coating.

- Foam rubber. In the beginning, from about the 1970s to the 1990s, foam rubber was sold without an adhesive composition. These were simply strips of foam rubber that were inserted into the cracks around the perimeter of the sashes. This method was good because the foam rubber could be pulled out if necessary to open the window and, after ventilation, stuffed into the cracks again. Sometimes, if ventilation was not required, strips of old newspapers, canvas, and later even medical adhesive tape and masking tape were glued over the foam rubber. Sometimes this option was used even until the 2000s-2010s.

- Band-Aid and masking tape . Insulation with adhesive tape gained popularity around 1970-1980, and later masking tape appeared. First, some porous material for insulation was stuffed into the cracks - cotton wool or foam rubber or old rags, and tape or adhesive tape was stuck on top. Oddly enough, this artisanal method is still used today. Sometimes it is even used for self-insulation modern windows with double glazing. Disadvantages: one-time insulation, damage to the paint and varnish coating of wooden windows, as for plastic and aluminum windows - in the spring you also have to wipe off the remaining glue and the profile is scratched, but besides this, for window fittings Such insulation options are disastrous - the fittings are stretched even more instead of the opposite operation - adjustment.

- Foam rubber and polyethylene foam, cut into thin strips. These materials appeared around 1990-1998 and quickly became popular. The insulation was smeared with Moment type glue and glued along the perimeter of the sash. With this method of insulation, windows could already be opened and closed. Insulation in terms of its thermal insulation characteristics was already quite satisfactory, moreover thermal insulation characteristics such insulation were the best of all handicraft and even modern methods, and besides, this window insulation has already been done for many years. The period of such insulation was approximately 5-8 years, and this option was a technological breakthrough in the field of insulation of window frames. All subsequent development in this area was reduced to the improvement of materials and methods of their fastening. Our company was actively involved in this insulation option in the period from 1993 to 2000.

- Self-adhesive foam rubber and polyethylene foam seals. Seals with an adhesive composition already applied appeared around 1997-2002. However, adhesive composition was very weak and to extend the service life the seals had to be coated with additional glue. In terms of thermal insulation, these options were inferior to previous non-self-adhesive seals, since the seal strips were too thin and did not cover the window cracks well.

- Self-adhesive rubber seals. Such seals appeared at the end of the last century and are still used today. One of the disadvantages is that the adhesive composition does not hold well and in order for this insulation to last for more than one season, the tubular seals must be additionally coated with the same Moment-type glue. The material used in modern self-adhesive seals is rubber. Among the disadvantages - it is afraid of paints and heavy pollution. And in general, the service life is still short, even if you glue it not on a self-adhesive basis, but spread it with additional glue, then this option will last up to 5-8 years, since the seal deteriorates from the ingress of paints, dirt, and also rubber with loses elasticity over time.

- Sealant. Replaced window putty. Designed for insulation and sealing of joints of fixed joints. Ideal and modern for insulating the junction of glass and window frame, as well as for other joints, for example, the junction of a window frame and a window sill or slopes. We use sealant widely in all modern window insulation options as one of the insulation elements, as component. But sometimes sealant is used as one of the artisanal options for insulation, using it not only for joints of fixed joints, but sealing the window tightly with sealant - sealing the gap in the narthex, at the junction of the sash and the frame. And this is not true. Since after this it is impossible to open the window for ventilation, and as a result, with the onset of a warm period, this sealant has to be peeled off, which is very labor-intensive. You can apply sealant to the window to cover both what is needed and what is not needed very quickly, but then it will take a long time to peel it off. Therefore, we recommend applying sealant only at the joints of fixed joints, where it will not need to be dismantled later, for example, to seal glass, which increases both the thermal insulation and sound insulation of windows.

- Polyurethane foam. Used for insulating seams around the window frame, foaming installation seams along the joint of the frame and window opening. Foam, like sealant, is not intended for insulating the false gap - between the sash and the frame. If you apply it along this joint, then how can you open the window? You'll have to really struggle in the spring to get it off. But around the box, around the perimeter of the window, foam is very necessary. For any windows - not only wooden, but also for plastic and aluminum windows. Foam is a porous material; it is the polyurethane foam that insulates the seam. (In ancient times, before the advent of foam, when installing windows, they made do with tow or old rags). And various sealants or adhesive tapes are applied on top of the foam to ensure safety polyurethane foam, to increase its service life, as it is destroyed by ultraviolet radiation, precipitation and temperature changes.

This is where we will finish the review of artisanal insulation methods, leaving out of the scope of our consideration completely exotic insulation options, for example, flour mixed with sheep or camel hair or straw mixed with clay or insulation with palm leaves, etc...

Today, there is an increasingly common service that allows you to repair old wooden frames, resulting in a new one. modern window, not inferior in quality and reliability to double-glazed windows. You can perform the procedure yourself or contact a specialist.

New product on the construction market

Relative newness renovation work raises doubts among many who decide to replace the window - financial side question allows you to significantly save on installing new windows, but will more just be worth it? cheap way? confidently declare the complexity self-execution this type of dismantling. Not everyone can make a selection along the sash, creating a groove for the seal. But having examined the process in detail, it seems possible to perform it yourself if you have the tools and materials.

Frame repair cost

The average cost and fitting of a window is about 3,000 rubles. This figure takes into account dismantling work with sashes, making grooves and filling with sealant, often silicone, if necessary, adjusting the sashes, sealing the glass, the sash opening - if the binding is paired.

Furniture work is paid above this amount. If necessary, for an additional fee, craftsmen will carry out a complete repair of the window frame.

In the case of framed windows in the manner of “Stalinist” windows, only the inner sash is insulated, leaving the outer one in its original state. When ordering insulation and an external sash, the price doubles.

The price list of organizations providing such services also includes a cost for coloring, which averages 5-6 thousand rubles.

Based on all the data, a complete dismantling will cost the cost of the window sill, bevels and ebb.

New window or repair of the old one?

The issue regarding windows in the house is decided depending on the circumstances, different for everyone. In one case, the output is overhauled, painted and sealed. In the second - plastic window. All other things being equal, given that the cost is approximately the same, not everyone prefers a new double-glazed window. The reasons are different for everyone, but reviews of the results of repairing old windows are only positive.

For reference!

The frame should not be rotten - replacement will increase the repair estimate by several thousand. First, they examine the lower section of the sash in those places where condensation accumulates on old windows, flowing down. If this part is rotten, restoration is not advisable in all respects.

Basics of the method

Swiss technology, carried out independently, allows you to minimal investment and a set of materials to make the window frame airtight, and the running parts to close and open well. Dismantling work takes place in any temperature conditions, therefore, even in winter, getting a high-quality window is not problematic.

Your name this type I got the repair thanks to the materials. Used in decoration Swedish seal , having a number positive qualities. This material has a tubular structure and is made of silicone, which allows it to be resistant even to sudden temperature changes. The temperature range that the Swedish seal can withstand is from 50 °C below zero to + 80 °C. Moreover, the material is highly resistant to moisture and dirt, and has a long service life - manufacturers promise from 15 to 20 years without repeated dismantling.

In order not to make a mistake and choose a seal that is suitable specifically for your case, you need to familiarize yourself with the markings. The diameter of the tube and its structure can be different, so the dimensions should be adjusted to the groove in which the tube will fit:

• E – groove 2-3.5 mm;
• P – groove 3-5 mm;
• D – groove 3-7 mm.

Preparatory work

When choosing Swedish technology for insulation and repair of window frames, you should consider mandatory requirement to the existing condition of the object being repaired - wooden frames must not be rotten, crumble or crack under pressure. If where condensation occurs there are only small gaps, they can be dealt with using putty and paint. In case of more severe symptoms, installation of a new window is inevitable.

The hinges should be tight, not wobble, changing the angle of passage of the sash, and the sash itself should not sag. If such descriptions are noticed, the fittings should be replaced. The window should effortlessly switch to the “closed”/“open” mode, without the slightest distortion.

In the absence of such problems or after minor restoration of existing defects, you can proceed to the insulation process.

Execution Sequence

To get the maximum quality window it is necessary to strictly adhere to the step-by-step work algorithm. Every owner may not have a set of tools at hand, but hardware stores often offer tool rentals, which can also be used.

Required tool set:

• Roller walker for laying insulation;
• Milling tool for preparing grooves;
• Screwdriver.

To begin with, do dismantling works. To do this, the running elements are removed from their hinges and the frames are untwisted. In some cases, it may be necessary to dismantle the glass. Removed frame processed by cleaning from dirt, dust, removing old paint. Availability small cracks, which do not go deep into the frame, are eliminated with putty. It is necessary to fill the gap that has been cleared of small dirt particles with a layer of putty, then leveling and wiping the layer flush with the surface of the frame. When the frame is in proper shape, a kind of double-glazed window is assembled with an additional layer.

On inside the sashes are secured sealing tape and sealed tightly. This technique will create a tight press. Silicone sealant is applied at the connecting junction of the frame and glass so as to completely fill the gap. Outdated glazing beads should be replaced with new ones. By adjusting the pressure, gaps are eliminated between the sash and the frame. Then comes the installation of the seal.

Using a milling tool, prepare a groove with an angle of 45°, performing the operation along the entire perimeter of the frame. The chips are removed from the finished groove and the surface is thoroughly cleaned. Into the finished groove install a tubular seal, selected according to the size of the grooves. To do this, from the corner of the frame, the edge of the seal is placed into the opening and gradually driven in with a roller walker.

For reference!

Other methods of fixing a tubular profile are not recommended. If you use nails for this, then over time the heads will rust and reduce the quality of the material. It is also not recommended to use glue for fixation, as it will lead to loss of elasticity.

Thus, the double-glazed window assembled using Swedish technology is ready. The inside of the sashes is dried with a hairdryer, and the finished frames are mounted in place and adjusted.

Conclusion

Independent performance of insulation and dismantling work according to Swedish technology is quite possible if you have a minimum necessary set tools and at least basic skills in construction industry. As a result, the window will seriously compete in quality and stability with any metal-plastic double-glazed window, and the costs of dismantling will be several times lower than if a new window block was installed.

From the video you will learn how to insulate an old wooden window using Swedish technology.

Each type of window (plastic, wooden) has its own advantages and disadvantages. But, if plastic windows are characterized by increased sound and thermal insulation properties, then wooden ones are inferior to them in this. However, it is quite possible to provide them with the desired characteristics.

Over the centuries of existence of wooden windows, many have been invented in various ways improving the heat-saving properties of old windows. However, they all affect appearance window.

This drawback can be eliminated by insulating wooden windows using Swedish technology or, to put it correctly, using groove insulation technology.

Swedish window insulation technology - what is it?

In fact, the authors of the technology are not Swedes, but they came up with the material used for insulation - EuroStrip. At the beginning of the century, the new product reached Russia and was tested in Moscow and St. Petersburg - major cities with historical heritage. Thanks to the use of groove insulation, the windows of historical buildings acquired heat-saving properties similar to PVC windows without changing their appearance.

Advantages of window insulation using Swedish technology

• The usual operating mode of the window is maintained. Unlike windows insulated with foam rubber and paper or fabric on top, a window insulated using Swedish technology can be opened/closed at any time of the year;

• improvement performance characteristics wooden window. Swedish technology is not so much insulation as partial, because... during the repair process, parts are adjusted, fittings are checked, worn components are replaced, glass is sealed, etc.;

• the noise level and the amount of dust that penetrates through the window in the summer are reduced;

• low costs for Consumables. When performing repairs yourself, all costs come down to purchasing a seal;

• execution of work at any time of the year. Due to the fact that the seal retains its properties over a wide range of temperatures, its installation can be carried out even in the cold season;

Note. It is better to carry out work at a temperature not lower than +5°C, because This lower limit for sealant, which is often used to additionally seal glass.

• environmental friendliness of insulation;

• technology can be used for;

• low cost of an insulated window compared to replacing it with a double-glazed window;

• no need for further insulation of the window;

• the properties of a wooden window are preserved: attractiveness, ability to ventilate, etc.;

• absence of condensation, which is typical for double-glazed windows installed in plastic windows. This is due to the fact that standard glass wooden frame are located at a greater distance from each other than in a plastic window, which reduces the intensity of heat transfer.

Craftsmen who perform window repairs using Swedish technology claim that it is very difficult to do the work yourself. As an argument, the need to possess professional skills and tools is voiced. But, as reviews indicate, repairs can be done on your own.

So, implement Swedish insulation It is quite possible to make windows with your own hands. The main thing is to choose a high-quality seal and have an idea of ​​the procedure for performing the work.

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 special material- EuroStrip seal. 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.

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: milling cutter (straight grinder at 300 rpm), roller for placing the seal in the groove, screwdriver, pliers, construction knife, 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, the rail should be increased 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;

• 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.

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 inner 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.

• 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.site
• 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. Device forced ventilation and periodic ventilation eliminate this circumstance.

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

Prices for window insulation using Swedish technology

Considering window insulation using Swedish technology, the question arises: wouldn’t it be cheaper to install a new plastic window and not waste resources on restoring a wooden one?

To compare, let’s look at the prices for services for insulating a wooden window using Swedish technology (only the internal sashes are insulated).

Main works include:

• removing the sashes;
• adjusting window sashes;
• groove extraction;
• installation of seal;
• glass sealing;
• installation of the sash in the frame;
• checking the functionality of the window.

The listed range of services for a 1.5x1.2 meter window will cost 2-3 thousand rubles. At first glance, it is inexpensive when compared with the cost of a new plastic window.

But this price is a starting point, because... More work will be done, for example:

• if you want to insulate the external sashes, the price will double;
• replacement of accessories is paid additionally;
• Painting is also not included in the standard package of services.

If we sum up all possible costs for insulation and restoration, then the cost will be 10-15 thousand rubles. A new plastic window will cost 20-30 thousand rubles. But installing a new wooden window with good double-glazed windows will cost 40-50 thousand. Since we are talking about preserving a wooden window, the amount of insulation and the cost of a new wooden window are comparable. The difference is significant, which is another argument in favor of using Swedish technology. And work done with your own hands means not only confidence in their quality, but also significant savings for the family budget.
