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 the 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, specialists will carry out complete renovation window box.
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, the lower section of the sash is examined in those places where condensate 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, with 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.
This type of repair got its name 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 there are only small cracks where condensation forms, 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. The removed frame is processed, cleaning it from dirt, dust, removing old paint. Availability small cracks, which do not go deep into the frame, are removed 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 flaps are secured with a 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 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, a double-glazed window assembled according to Swedish technology, ready. The inside of the sashes is dried with a hairdryer, and the finished frames are mounted in place and adjusted.
Conclusion
Carrying out insulation and dismantling work independently according to Swedish technology is quite possible if you have the minimum required set of tools and at least basic skills in the 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.
What to do if there is no money to replace windows, or the old windows are still in quite good condition, and only cracks have appeared in places? There is a solution - insulate the windows using Swedish technology. You will spend a minimum of money (5-7 times less than on new windows), and in return you will forget about drafts, frozen glass and noise from the street. You can reduce costs even further by doing the insulation yourself.
Technology
The very name of this insulation method comes from the fact that the tubular seal, the main component of the technology, was originally made in Sweden. Now there are many analogues on the market that are not of worse quality, but much cheaper in price. The name stuck firmly.
"Swedish" insulation - a hollow highly elastic rubber tube, the most common type of EuroStrip from Trelleborg. It is very flexible, withstands large temperature differences, and is resistant to ultraviolet radiation. It fills all the gaps or shrinks into a thin layer depending on the specific window and blocks the penetration of wind from the street. The seal itself can be washed and painted. Even with fairly active use, it will last for 10-15 years.
In addition to installing the sealant, the sashes are adjusted, they are aligned, if necessary, they are rehung (). They fix the glass itself in the frame and seal the cracks under the window sill. If the bindings are double, clean the space between them and seal the cracks there.
Ideally, you still need to remove the old paint, sand the frame and binding and paint again, as many years of paint build-up interfere with dense burying of windows. Unfortunately, companies offering Swedish technology window insulation often ignore this stage, which worsens the quality of work and the long-term result.
Restrictions
Insulation of wooden windows according to Swedish technology is possible for almost any window, except for those that have completely rotted from time to time. It is problematic to insulate warped windows, with sagging sashes and broken fittings. It's easier to put a plastic one.
It is better to carry out insulation work in summer or early autumn, since the window will remain open for several hours, and in the case of painting, even longer.
Material and tool
It’s worth taking on your own compaction if you have experience in carpentry and the appropriate tools. You need to make channels in the window sashes, so you will need a cutter. You can’t do without a screwdriver, chisel, plane and sandpaper(or grinder). If you plan to paint, you will need a hair dryer, a primer, wood paint, a roller and brushes. Consumables needed:
- interframe seal,
- EuroStrip tape (or similar),
- transparent silicone sealant,
- wood putty or mastic.
The required number of seals can be calculated by measuring the perimeter of all sashes.
Preparation
First of all, you need to remove the doors from their hinges. Inspect the hinges, ties, bolts and latches and determine whether they need replacement. If the paint on the window is old, peeling off in places, or applied unevenly in many layers, it is better to remove it. The easiest way to do this is to heat it up section by section with a hair dryer and remove the paint with a chisel. The cleaned frames and sashes are trimmed with a planer, if they were not closed well before, they are sanded. Scratches and grooves in wood can be filled with putty.
Window insulation
If the sashes were cleaned of paint, then they are painted again, and when they dry, they are collected. An inter-frame seal is inserted between the frames. It protects the space between the doors from dust and serves as additional insulation.
Then the sashes are twisted, and a thin recess is cut along their perimeter with a cutter, into which the EuroStrip is laid. You can not make a groove, but stick the tape on the tree, but in this case it will wear out faster, and it will not fit so tightly.
Glass at the junction to the frame, the junction of the glazing bead with the frame are glued silicone sealant. This is done to prevent moisture from getting inside and improve. The sealant is also placed in the cracks between window frame and wall. Large cracks are easier and faster to seal with mastic or putty. The voids and cracks under the window sill are foamed with polyurethane foam.
The sashes are hung on hinges and the fittings are adjusted. If everything is done correctly, then the window closes easily, and the handle turns effortlessly. You can check the quality of the seal by carrying a lit candle around the perimeter of the window and all the sashes. If the light does not deviate, then the wind will not blow into the cracks in winter.
Windows insulated using Swedish technology become almost completely airtight. To ensure sufficient fresh air flows in, it is better to install a fresh air ventilation valve under the window.
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 the existence of wooden windows, many 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 - large cities with a 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.
Benefits of window insulation using Swedish technology
- the normal 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;
- improving the performance of a wooden window. Swedish technology is not so much warming 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;
- performance 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 perform work at a temperature not lower than + 5 ° С, because This is the lower limit for the sealant that 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.
This means that it is quite possible to implement Swedish window insulation 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 of a 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: 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, 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 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.
- 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 performance of the window and the tightness of the sashes to the frame are checked.
Note. Swedish window repair technology involves the replacement of old hinges, wraps, latches, glazing beads and other window fittings.
How to insulate old wooden windows using Swedish technology - video
Please note that after being insulated according to Swedish technology, the windows will become airtight, as a result, this may lead to a violation of 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 the insulation of windows using Swedish technology, the question arises, would it not be cheaper to install a new plastic window and not spend resources on restoring a wooden one?
To compare, let's take a look at the prices for wooden window insulation services using Swedish technology (only 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 the installation of a new wooden window with good double-glazed windows will cost 40-50 thousand. Since we are talking about preserving a wooden window, the following are comparable: the amount of insulation and the cost of a new wooden window. The difference is significant, which is another argument in favor of using Swedish technology. And do-it-yourself work is not only confidence in their quality, but also a solid savings for the family budget.
A warm home is the key to coziness and comfort. In addition to insulating walls, floors and ceilings, it is important to properly insulate windows. There are many methods for insulating windows with your own hands, but the highest quality and most popular is Swedish technology.
This method is ideal for working with both old wooden windows and new frames, regardless of the coating method and window design.
The essence of the technology is the installation of a special tubular seal. This method will require a lot of effort and the presence of certain skills and tools. However, all the effort spent on the work will pay off by saving time and money. As they say, the miser pays twice.
Cost of insulation using Swedish technology
The cost of installation sometimes exceeds the cost of new frames. However, this disadvantage is compensated by the quality of operation and its duration. Insulated windows will serve the owner for at least 10 years. This is due to the expensive materials used for insulation and unique technology.
This method was developed by Swedish engineers and can significantly reduce heating costs even in harsh climatic conditions.
In this way, you can insulate both plastic double-glazed windows and wooden windows. When insulating a wooden window using this technology, the effect of a sealed double-glazed window is obtained, similar to high-quality new plastic windows.
In case of plastic double glazed windows Insulation is carried out if the windows are of poor quality or have received mechanical damage.
Advantages of Swedish insulation technology
If you decide to insulate your windows yourself, this can be done with minimal investment. The main cost is installation. In order to begin work on window insulation, it is necessary to study the installation algorithm in detail. We present you with video instructions:
Only after acquiring the necessary knowledge and skills can you begin to work, since the technology itself has a lot of difficulties. So, what are the advantages of Swedish technology:
- complete sealing of the window frame and opening;
- high level of sound insulation;
- minimal penetration of dust and dirt into the room;
- saving money and effort. By performing insulation using this method, you save yourself from the costs of annual frame treatments or purchasing a new window;
- environmental friendliness - the material from which the rope is made does not contain toxic substances, and during operation does not emit resins and other compounds;
- durability, the tubular seal is made of a special material based on rubber and silicone, which in addition to its functional features not exposed to harmful environmental influences.
As a result of insulating windows using this method, you will receive protection from drafts and save heat, and a high-quality seal will serve you for many years and will maintain an aesthetic appearance, unlike an ordinary seal, which changes color over time, becomes dirty and peels off.
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 from a unique material that is not exposed to natural conditions, chemical substances, dirt and temperature differences. The service life of the heater, under the manufacturer's warranty 15-20 years.
Stage number 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.
Window state diagnostic algorithm:
visually inspect the external condition of the frame;
Important! Please pay Special attention on the safety of the lower 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 loops: they should not sag, but have a good design. If the hinges are faulty, they must be replaced;
- check if 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 number 2. Glass sealing
We measure the window and calculate the required footage of the sealant. 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, remove the glass and process the joints with sealant. Then mount them back and secure with glazing beads. Sealing the glass joint will enhance the effect of insulation.
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
Along the perimeter of the frames we make markings for the groove. 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 cut 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. With the help of 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.
Features of the material
When buying a sealant, you must carefully examine its quality and operational properties and pay attention to the manufacturer. Not always the rope presented on the shelves construction stores, is the original. As a rule, low-quality fakes will serve you for a maximum of 1-2 years, while creating problems during operation.
The original material does not deform and retains its appearance and “working” properties for several years, and is not exposed to critical temperatures and their fluctuations.
The seal is available in several forms depending on the size, with a diameter of 5-6-7-8-10-12 cm. For each case, you can choose the best option.
Swedish window insulation technology has its own subtleties and secrets. We hasten to introduce you to some of them:
- painting or varnishing a window frame insulated using this technology is carried out only after completion of the work. Otherwise there is a risk of surface damage. It is recommended to paint the surface without touching the insulation;
- some types of structures window frames, for example, frames in “Stalin” frames need to be insulated only from the inside, this is required by the design features - separate binding;
- To carry out insulation work, in addition to the standard set of carpentry tools, you will need special tools: a roller for pressing the seal, a special cutter for cutting a groove;
- Window insulation using Swedish technology allows you to achieve high levels of thermal insulation of rooms, significantly saving your budget on heating and purchasing new expensive double-glazed windows. And the durability and quality of operation will save you from the annual hassle associated with insulating structures using traditional methods.
