Insulation of wooden windows using Swedish eurostrip technology. Insulation of wooden windows using Swedish Eurostrip technology Seals for wooden windows using Swedish technology

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 there is a 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

Choosing Swedish technology for insulation and repair window frame, should be considered 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 removing dirt, dust, and 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.

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 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 V 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.
For all its effectiveness this method requires purely symbolic costs that even a pensioner can afford.
With 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 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 old paint the window has peeled off and needs to be removed and the entire structure repainted. WITH wooden surfaces paintwork 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 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

For wooden frames Soviet period, we offer a modern groove version of window insulation using the Swedish EUROSTRIP technology.

If you are used to your old wooden windows, then the technique proposed by Swedish engineers will appeal to you. Using technology " Eurostrip» you don’t have to part with your favorite wooden windows - insulation wooden windows will give them new life!

Swedish technology guards your comfort!

Brand " Eurostrip» is a division of the famous Swedish manufacturer of household sealants www.trelleborg.ru. In the wide range of products you can find a wide variety of rubber products and, in particular, seals for doors and windows. Anyone who wants to learn more about materials, their properties and characteristics can easily find this on the Internet on the concern’s website. Products come out of a line of factories, each of which has all the accompanying information printed on it.

Window insulation using the Swedish Eurostrip method involves the following operations:

Removing the sashes from the window.

Applying a special seam along the edge of each sash. The seam is made using a router and its first and only purpose is to hold the window seal in place. dimensions the seams are approximately 3 millimeters wide and 8 millimeters deep.

Seam placement of high quality Swedish seal Eurostrip. The sealant material is silicone rubber, the properties of which far exceed those of simple rubber.

If removing the sashes is quite problematic, then you can use the following option - cut a seam with a router directly in the window frame itself and lay the seal in it.

Rationale for using silicone rubber

Silicone rubber is used to insulate windows, and this is by no means accidental. This material is far superior to simple rubber in the following properties:

Resistance to varnishes and paints. Silicone rubber practically does not interact with varnishes and paints, which is ensured by its high chemical inertness. In practice, it looks like this - when drops of varnish or paint fall on the surface of silicone rubber and then dry, they are erased almost effortlessly, without damaging the surface in any way. If such a nuisance happens to ordinary rubber, then its surface will immediately lose all beneficial properties. By the way, contact with the paint of the thermoplastic fin seal ends extremely sadly - after a while it completely looks like an unsightly substance. It is important to keep in mind that the optimal period of time to wait before starting to peel paint droplets off the surface of the silicone sealant is 12-15 days.

Elasticity. The importance of elasticity in window insulation cannot be overestimated. The more elastic the seal is, the better the connection between the sashes and the frame will be and, accordingly, the warmer the room will be. Over time, poor contact of the seal and sashes with the frame can cause both the drying out of the entire window structure and the failure of fasteners and other fittings. The silicone seal guarantees a seamless connection.

Durability. Thermoplastic elastomer and regular rubber are significantly inferior to silicone rubber in terms of durability and wear resistance. Silicone works in a wide temperature range and is therefore often in demand in winter.

We work in Moscow and the Moscow region, our company provides a warranty period for the insulation of wooden windows
groove method 3 years!

The cost of insulation already includes adjusting the sashes, as well as sealing the glass and frame.

The service life of such a modified window is at least 10-12 years.

An insulated window transmits sounds much worse, so the noise level from the street when closed window will decrease significantly. In addition, the mechanisms of an insulated window operate much more smoothly than before insulation.

For change appearance windows require window painting, it can be ordered simultaneously with insulation or separately!
