It is known that it is through the windows that the room gives off almost 40% of the heat. And it’s not even a matter of drafts that seep through the cracks of loosely fitting wooden frames. The glass itself is a conductor of heat, as it transfers it from the inside into the street air with its entire surface. Insulation of windows using Swedish technology and insulation of slopes, thermal film, proven over the years " traditional methods“- any method, to one degree or another, helps to keep the house warm if done correctly.
Many people believe that in order to keep the house cool through the window openings, it is enough to install plastic windows. When installing PVC windows, their openings are actually insulated with mineral wool and polyurethane foam. Many people do insulation plastic windows do it yourself - insulate with polystyrene foam internal slopes etc. The windows themselves are designed in such a way that they conduct heat to a lesser extent than windows with ordinary glasses. However, what to do if it is not possible to install a double-glazed window?
Wooden windows
Of course, dried out wooden frames should be replaced during repairs. And these may well be plastic windows. But don’t rush to replace high-quality wooden “joinery” just to make the house warmer! You can use a proven method, for example, sealing with foam rubber and sealing window cracks. There are other similar methods, although they all have several common disadvantages (windows cannot be opened in winter, and they need to be cleaned in spring), many still use them.
The fastest and easiest way to quickly and tightly seal window cracks is to fill them with molten paraffin. Heat the paraffin in hot (about 70 degrees) water, put it into a syringe without a needle and pour it into the cracks. There is no need to seal the cracks over paraffin; it does not crumble or fall out.
If you decide to putty your windows, keep in mind that the most handy tool For " window works"is not a construction spatula at all. The most convenient way to do this is with a metal shoe horn. Its semicircular shape allows you to smooth out the putty, remove excess and form an even, smoothed seam.
Warming "inserts":
After caulking or caulking the external cracks, they are sealed with strips of paper, fabric or paper (painting) tape. It is not recommended to use transparent polyethylene tape - it insulates cracks well, but breaks easily and often falls off. It’s even easier to seal the window cracks with medical adhesive tape. It is not blown through, is not afraid of moisture, and after peeling off it leaves no marks. Paper or fabric strips are glued with starch paste or laundry soap.
One of the main disadvantages of the “old-fashioned” methods of preserving heat in the house is that windows sealed in this way cannot be opened until spring.
If you carry out insulation wooden windows According to Swedish technology, windows can be opened and closed at any time of the year. This is convenient, for example, for insulating a wooden balcony door. Particularly important is the ability to open balcony door in apartments with a glazed but uninsulated balcony.
Insulation using Swedish technology
For “Swedish” window insulation you will need a hollow tubular seal (insulation) and a transparent silicone sealant. If necessary, use sealant to seal cracks in the area of slopes and cracks in places where the glass is adjacent to the frame. Before starting work, you need to check, adjust and fit all window mechanisms (hinges, locks, latches).
This method of insulating window frames is used for classic wooden windows. Although at first glance it may seem that such work is not difficult to carry out on your own, it is better to entrust it to specialists. They will not only do everything faster and better, but also use materials they are confident in. The best confirmation of how effective and reliable window insulation using Swedish technology is is the reviews of those who, thanks to it, decided not to change wooden frames to metal-plastic ones.
Before starting work, the window must be washed. Check how the doors open and close and whether the locks and hinges are jammed. Now remove the window from its hinges and take it to where you will be working on it. Window insulation is best done on the balcony or on staircase, because after work a lot of garbage remains. The doors are insulated both between each other and inside.
Many people have heard about insulating plastic windows with film. Heat-saving film is also used to insulate wooden windows. You can do this yourself, since there is nothing complicated in working with film. To do this you will need double sided tape, stationery knife, scissors and an ordinary (non-construction) household hair dryer for compacting the film after gluing. Before installing it, you need to remove the handles from the window.
Windows with heat-saving film pasted
If the film inflates like a sail, there are drafts somewhere inside the frame. You will have to remove it, disassemble the frame, go over it outside and inside along the glass with transparent silicone sealant and repeat the gluing. Torn film can be easily repaired with ordinary stationery tape.
Heat-saving film increases the room temperature by 4-5 degrees and keeps it at a constant level for eight hours. This is one of the simplest, cheapest and effective ways allowing to insulate residential or production room. It is not for nothing that heat-saving film is sometimes called “third glass”.
Work order:
The easiest way to insulate the slopes of windows with plastic or wooden frames is to use plasterboard or ready-made sandwich panels. Insulation with plasterboard panels is carried out as follows:
Laying insulation in the groove
Insulating slopes with sandwich panels is even easier. Attach a U-shaped profile around the entire perimeter window frame. Since sandwich panels are thicker than drywall, cutting grooves for them, as in the previous case, will not work.
Now cut the slopes of the required size from the sandwich panels and insert them into the fixed profile. The space between the panels and the wall is best filled mineral wool. After this, the mounting F-profile, into which the same sandwich panels or plasterboard plates are installed frontally.

Hello. Today I'll tell you about self-insulation windows in the apartment and in country house. Thermal insulation of windows is very important stage real estate renovation, which should not be neglected if you are interested in the energy efficiency of your home and reasonable heating costs.
Today, many methods of thermal insulation are known. The choice of one method depends on the type of window.
This time you will learn how to make ordinary wooden windows and modern double-glazed windows warmer. In addition, I will talk about how to insulate openings outside the house with your own hands using inexpensive polystyrene foam.
High quality made plastic double glazed windows are equipped with special rubber seals, which, due to their tight fit to the frame, prevent the passage of air from outside to inside the room.
The areas through which cold passes are:
So, what methods of metal-plastic double-glazed windows can be used for insulation?
Even after high-quality plastering of the slopes, a micro-gap remains. If this micro-gap is not sealed, it will cause cold air circulation and condensation. As a result, fungus may appear at the junction of the slopes and the frame.
To close the gap you will need the following materials and tools:
Instructions for sealing seams are given in the following diagram.
Let's consider the listed stages in more detail:
Sanitary sealant is completely removed with white spirit within 20 minutes after application. After 20 minutes, the sealant will be very difficult to remove.
Now the most important thing you need to know when filling the gap between the slopes and the frame with sealant.
Typically silicone is applied as follows. A person stands near the window sill, places the tube with a cone to the gap at an angle of 45-60 degrees and guides the tube towards himself.
As a result, the sealant is squeezed out by the worm, and it has to be leveled and smoothed with a finger, after which the adjacent surfaces must be cleaned. Even if you remove the silicone deposits, a layer of several microns will still remain and after a couple of weeks a streak dirty with dust will be visible in this place.
To ensure that the silicone gets into the gap and nowhere else, we apply the cone of the tube at an angle of 45 degrees and move it forward, and not towards ourselves. As a result, the tip of the cone will straighten the seam itself and there will be virtually no contamination on the sides.
For insulation of conventional double-glazed windows or a balcony with panoramic windows Not just any silicone is suitable; in extreme cases, we use sanitary sealants that will not mold later.
Plastic windows at home can be additionally insulated with heat-saving film. No, now I’m not talking about covering frames with tape, that’s of no use here, I mean shrink film, which can be used to create an additional air chamber between the glass and the room.
Did you know that the greatest heat loss is on modern double glazed windows Are they registered not in the frame area, but directly on the glass?
Manufacturers convince us that argon or other inert gases, which are less thermally conductive compared to air, are pumped between the two glasses. But the problem is that the gas layer works for 2-3 years, after which the space between the two glasses becomes airy.
Solving this problem is not difficult, I showed how to do it in the diagram.
Let's look at the stages listed in the diagram in more detail:
The easiest way to clean the junction between the glass and the frame is to remove any accumulated dirt using a stiff toothbrush. Glass can be easily washed away from the most difficult stains by vodka applied from a spray bottle and subsequently collected with a special scraper.
The use of thermal film cannot be called innovative, since this technology was used back in Soviet times. Then ordinary polyethylene oilcloth with the help of a wooden glazing bead was stuffed onto the window from the outside for the winter.
And what did we get as a result? As a result of this installation, the room was darker than usual and about beautiful views out of the window could be forgotten until spring comes.
The use of special shrink film is completely free of such disadvantages. Again, if earlier with the onset of the warm season the oilcloth was removed from the frames, today this is not at all necessary, since the thermal film is absolutely transparent.
By the way, in summer there is additional air gap between the glass and the film will prevent heat from penetrating into the room.
Thermal film can be installed with equal success on both plastic double-glazed windows and wooden windows. True, in the latter case, the wooden frames will have to be pre-aligned and painted.
Do you have wooden windows in your apartment or house and even foam insulation doesn’t protect you from the cold? Of course, you can change the old ones wooden structures for plastic double-glazed windows. On the other hand, you can leave environmentally friendly wooden windows, but make them much warmer.
Now I’ll tell you how to insulate wooden windows for the winter using Swedish technology.
Many people have heard something about Swedish technology, but not everyone knows what it is. In a few words, the Swedish technology for the restoration of wooden windows is a complex work, as a result of which a wooden window in terms of thermal conductivity will be comparable to plastic double-glazed windows.
The main stages of working with old windows using Swedish technology are listed in the following diagram.
Let's consider the listed stages in more detail.
If the glass in the frames has cracks or small chips, they must be replaced immediately, otherwise the insulation will be of no use.
So now you know what Swedish technology is. The question is, how advisable is it to do the listed work yourself or still order window restoration from specialists?
It would seem that this is a question, because specialists will have to pay, while you can do everything with your own hands for free. But in reality this is not the case, since you will have to buy a router and a pressure roller. The price of such a tool is high and it is unprofitable to buy it to insulate windows just once.
You can insulate wooden windows with your own hands not only from the inside, but also from the outside. The method that I will now tell you about is the optimal solution for budget thermal insulation of a country house.
To perform thermal insulation you will need the following materials and tools:
What can be insulated with polystyrene foam? This method will allow you to seal old platbands or finish external slopes without the need for cementation. In addition, carefully executed cladding will certainly decorate the facade of your home.
The instructions for performing thermal insulation are as follows:
We take into account that the width along the length of the slope on old windows can be different, so we use the largest value.
Expanded polystyrene, which is shown in the photo report, has a high density and therefore can be used without additional finishing. However, if you decide to plaster your home, foam board trim can also be plastered over a paint grid.
You can learn how to plaster foam boards from my relevant articles.
I told you what I knew about insulating windows in the house. Do you know any effective ways besides those listed? Tell us about it in the comments to what you read. In addition, I recommend watching the video in this article, I think it will be interesting.

Any window needs additional sealing. This is especially important if street noise has increased, a draft has appeared, and heat is lost in winter. It is best to do insulation in warm weather. Many methods are used for this, including replacing the window. Fortunately, there are Construction Materials that successfully solve this problem. This material is considered to be insulation tape.
The microclimate of the room depends on the windows. Due to uninsulated windows, the glass fogs up, cracks and fungus appear on the slopes, and there is always a draft and street noise. To effectively insulate windows, it is necessary to determine the reasons for low thermal insulation.
Most often they are the following:
First of all, insulation is required for old window structures for the following reasons:
It is mistakenly believed that such windows are quite airtight and therefore do not need insulation. Unfortunately, after a few years the seal collapses, and insulation is indispensable.
There are other reasons why it is necessary to deal with plastic windows:
The widespread use of tapes for insulating windows is explained by a number of reasons:
But this method of insulation also has disadvantages:
IN construction stores They offer two types of tapes, which differ in the installation method.
Foam tape with adhesive base
This type of tape has a wide grip. Adhesive composition applied during manufacture (self-adhesive type) or during installation work.
To create self-adhesive tape, polyvinyl chloride, rubber and polyethylene foam (foam rubber) are used.
Due to the plasticity of these materials, the tape is easily compressed to the size of the gap. To ensure that the insulation does not stand out against the background of the window, dyes are added: black, brown, white.
Typically the packaging will indicate the size of the gap that the tape will cover. Popular options with sizes 3 - 7 mm.
The first to be used foam tapes. Their popularity is explained by a number of advantages:
Such tapes have negative qualities:
Important!
It is more convenient to use self-adhesive tapes on foam rubber for insulation.
They stay on the window longer and regulate the degree of pressing of the sashes.
D - shaped tubular seal with adhesive base Tapes of this type have a hollow tubular shape, which is why heat is retained. The materials chosen are rubber and polyvinyl chloride.

On one side of the tape there is a groove hook or adhesive coating with paper protection.
It is believed that the groove is more resistant to mechanical stress.
The following qualities are considered advantages:
But most of the disadvantages relate to adhesive tapes:
Tubular seals are checked annually. If necessary, individual fragments are replaced.
As a rule, a tape is selected based on three indicators.
Main advantages:
There are also disadvantages:
Unfortunately, such tapes are rarely used for window insulation, as they become more expensive window design up to 15 %.
Tubular seals with groove Self-adhesive tapes are made on the basis of synthetic rubber and have all of its positive traits: elasticity and resistance to temperature fluctuations.
Rubber seals are not afraid of aggressive environments, so they last a very long time.
Due to their high elasticity, the tapes are very effective for small gaps. Good insulating qualities. Due to the presence of air in the structure, a thermal insulating environment is created.
Its use is limited to its ability to high temperature turn into a liquid toxic state.
In construction stores you can find tapes from different manufacturers.
However, only materials from the following brands are in demand:
Domestic manufacturers, as a rule, work using European technologies and produce high-quality material no worse than foreign samples. At the same time, German and Polish ribbons, although more expensive, last longer.
Insulating tapes are sold retail and in coils from 6 to 10 meters.
Because for standard window About 5 meters of self-adhesive insulation is needed, then most often it is purchased at retail.
The price range is very wide.
Behind linear meter Russian material you need to pay up to 15 rubles, and the most expensive German rubber insulation will cost 50 rubles.
Preparing a window for insulation with tape is almost no different from preparation for other insulation materials. At the same time, there are some peculiarities.
The main stages are as follows:
How to get rid of heat-blowing drafts? How to insulate wooden windows if it blows from the cracks as if there were no windows at all? Of course, you can use the old fashioned method - plug the cracks with soaked newspaper and glue paper on top. But it won't bring much warmth. In addition, in the spring you will have to tear off this paper. And, quite possibly, along with the paint. Of course, if you still plan redecorating, nothing bad will happen. And if not? The frames will still have to be repainted so that they don’t feel embarrassed in front of the guests.
A more acceptable method is to fill the cracks with foam rubber (you can use cotton wool), and then glue them with strips of fabric. This is done as follows. Strips of fabric are cut five centimeters wide, moistened, wrung out, and then thoroughly lathered with soap. This method is good because the fabric does not turn yellow over the winter. And in the spring it can be removed very easily without catching the paint. Just wet it warm water.
How else can you insulate wooden windows? Try this method. Take regular paraffin (in other words, a candle), melt it, and then use a syringe to inject it into the cracks. Within an hour, the paraffin will harden, creating an insurmountable barrier to drafts. True, you will have a hard time cleaning your windows in the spring. But believe me, it's worth it!
An ordinary linen cord may well be suitable as insulation. If the draft comes only through the glass part of the window, replace the old glazing beads. This should help.
As you probably already understood, everything that was listed above are methods that have been proven for decades, which are passed on from mother to daughter, from father to son. Of course, they will help get rid of drafts and keep the house warm. However, this is, whatever one may say, the twenty-first century. This means that new technologies are appearing in all areas, and old ones are being modernized. And to the question: “How to insulate wooden windows?” New answers are already being found.
Do you know how to make the radiator bring more heat into the house? Very simple. Surely (this happens in most houses) it is painted white or pale green. Feel free to remove the paint and repaint it - only in dark shades.
The fact is that a dark surface does not absorb heat, but reflects it. Accordingly, the battery will provide all the heat to the apartment. If this is not enough, paint a sheet of plywood with silver and place it behind the radiator. You will get a good reflective screen. Thanks to this, the battery will no longer heat the walls. A sheet of foil will give a similar result.
If all of the above methods do not suit you, we can tell you how to insulate old wooden windows using the latest insulation. Let us remind you that some of them can only be used at above-zero temperatures.
So, how can you insulate windows? The best sealant Today pipe profiles are recognized. In everyday life they are called sealing gaskets. There are three types of such profiles: D, E and P. The choice of profile type directly depends on the size of the gaps to be sealed. This insulation has many advantages. It is invisible to guests, does not interfere with opening windows, and is durable (on average, the shelf life of sealing gaskets is about five years). However, there is one very significant drawback. The pipe profile can only be glued at temperatures above minus ten degrees. In addition, gluing it is not so easy.
As for the material from which the pipe profile is made, it is environmentally friendly. These are foam rubber, polyurethane, polyethylene foam, polyvinyl chloride or rubber. The latter are both self-adhesive and those that need to be glued with glue. From this variety of pipe profiles, we advise you to purchase those made of polyvinyl chloride. They tolerate frost well, practically do not deform or break. But rubber ones are more durable.
If you can’t decide which is better to buy: a self-adhesive seal or one that you have to tinker with during installation, listen to common sense. How to insulate old windows with self-adhesive insulation? Very simple. Removed protective film, sealed the cracks - and everything is ready. But will it last all winter? Most likely not.The second option is more reliable. The main thing is to choose the right glue. Perhaps silicone sealant will suit you here. It stretches and contracts perfectly, and also repels moisture. Most importantly, silicone sealant holds even when windows are constantly opened.
If you decide to make your home truly warm, pay attention to front door. It can also be treated with self-adhesive insulation or simply covered with foam rubber around the perimeter. Most houses in Russia are made of panels. And cracks, as well as weakly cemented interpanel seams, alas, not uncommon. If all this is present in your home, insulating the windows alone will not save you. Insulate doors, seal cracks, seal interpanel seams, and ask housing and communal services to seal the windows in the entrance. Be sure to glaze your balcony if you haven’t done so already. Only by performing comprehensive insulation of the apartment and entrance will you ensure that your home will be warm and cozy even in the coldest winters.
What should you do first to save heat in your house or apartment when cold winds blow outside and the temperature begins to steadily slide down? The answer is simple; first of all, it is necessary to resolve the issue of how to insulate windows for the winter.
In fact, insulating windows with your own hands does not require special skills.
One of the cheapest and simple ways insulating windows (one might say the “old-fashioned” method) is sealing windows with strips of paper smeared with paste. It is advisable to caulk the window cracks first. technical wool or foam rubber. If there is nothing suitable at hand, then newspaper paper is torn into small pieces, soaked in water and the resulting mass is used to plug the cracks between the frames. For this work, use a sharp knife with a thin blade, a flat-edged screwdriver, or any other thin, sharp object, even a metal ruler.
Preparation of paste:
While stirring the flour (starch), gradually pour half a glass of cold water. After the formation of a homogeneous mass, pour in a glass of boiling water in a thin stream.
Don't forget to constantly stir the mixture. Make sure that the thickening paste does not form lumps so that the mass remains homogeneous. If the mixture does not thicken well, it can be heated on the stove (stirring constantly) until bubbles form on the surface of the mixture.
After this, cool the paste by placing the dishes with it in a bowl with cold water. The paste is stored in the refrigerator in a tightly sealed container. But do not forget that every day its adhesive qualities are deteriorating. From practice, the paste keeps well in the refrigerator for 4-5 days.
Warming process:
In spring, moisten strips of paper with warm water. After 5-10 minutes, the dried paste will swell and the paper can be easily removed. All you have to do is wipe damp cloth frames
Instead of paste you can use regular laundry soap. Moisten it in water and pass it over the paper several times, “rinse” it well. After that, glue it to the window.
The disadvantage of this method is that if the cracks allow a lot of air to pass through, the paper will not hold up for long. By sealing the cracks, the strips of paper will not fall off until spring. In the spring, wet the paper and it can be easily removed from the windows.
Instead of paper strips you can use stripes of light fabric. The technology is similar to the previous method and is as follows:
If you don’t want to bother with paste/soap solution, you can seal the windows special sticky paper (paper tape), which is freely sold in retail trade. But keep in mind that if you have old painted windows, removing the specified tape in the spring may leave paint from the windows on it.
Another way to insulate wooden painted windows. Seal all cracks with regular gypsum putty.. It is sold in hardware stores in the form of a white powder. 
Dilute the powder with water until the thickness of softened plasticine. It is best to cover cracks by hand, without any tools. Wipe the affected areas with a damp cloth to remove excess putty. On windows painted with white paint, the places where the putty was applied are practically invisible.
In the spring, such windows open easily, but most of the putty falls off. Residues are easily removed.
Throughout the entire cold period, windows covered with putty do not allow cold air to pass through at all and retain heat well.
Another method worth mentioning is Filling window cracks with paraffin. To do this, ordinary candle paraffin was heated in a water bath at a temperature of approximately 65-70 degrees and then this paraffin was poured into the cracks using a similarly heated syringe.
For high-quality and long-term insulation of wooden windows, use silicone sealant. In this case, it is advisable to purchase a lever syringe. A container of sealant is inserted into a lever syringe and by pressing the lever, the required portion of silicone is squeezed out. It is better to use a transparent sealant; if it accidentally gets on the windows, it will be little noticeable.
Warming process:
Advice: In parallel with this method of insulation, you can immediately repair the frames (since the frames are removed: o). Take off old paint, fill cracks and knots, cover up cracks. At the same time, you can change the fittings by installing more modern and reliable locks and latches. All this will also affect the thermal insulation of the apartment.
Efficient and inexpensive way window insulation is use of adhesive polyurethane seals with a tubular profile. This method is great if cold air enters the apartment through the gaps between the frames. True, this method is rather a repair and insulation of windows, as they say, “in one bottle,” since it will not be possible to do without additional work.
The insulation is attached to one side of the window frame - along the perimeter of the transom. When closing, the frame will bend the seal at an angle, and thus block the flow of cold air into the gap. Remember, the products adhere well to the base at a temperature of at least ten degrees. So don't delay thermal insulation on the back burner. The sooner you do it, the better.
It is important to position the seal in such a way that the frame bends it and does not slide over it. Otherwise, such insulation will be of little use.
Before gluing the seal, the surface of the frame must first be prepared - remove peeling paint, clean the frames from dust and dirt.
If necessary, the surface of the frames can be sanded with fine sanding sandpaper, degrease with acetone or solvent.
You can glue in one row or, if the width of the frame allows, in several, parallel to each other. If you chose a seal with an adhesive surface, it is better to nail it along the edges with small nails for greater fixation.
The undeniable advantage of tubular profiles is the ability to open or close the doors at any convenient time. Thanks to this, ventilation of rooms during the cold season ceases to be a problem.
Tubular-type profiles have a durability of five to six years.
And finally, let's look at another way to insulate windows - insulation of windows with film. You can use regular plastic film. It is attached to the outside of the window, and if the windows are located at a height, then from the inside.
The entire window is covered with film, securing it along the outer edge of the frame. The film must be evenly stretched, otherwise the wind will tear it in places of weakness.
Choose frost-resistant film, ask the seller about it in advance. Usually the frost-resistant film has a yellowish tint.
The film is secured with push pins through some kind of lining (you can use fabric tape, or cut pieces from a thicker film) to avoid tearing the film over time at the attachment points.
If you have an industrial stapler, it will make your task of attaching the film easier. It is also necessary to place a pad under the staples.
A relative innovation is the use of heat-saving films. They let light into the room, but do not “let it out” infrared radiation, thus retaining heat. Such a film has two sides, one with a metallic sheen and conducts current, the other does not. When gluing film to glass, you must make sure that it “looks” at the street metal side- that's the whole point.
It should be glued overlapping onto the frames and secured with tape. If you stick it carefully, its presence will not even be visible.
There are quite a few ways to insulate wooden windows. Choosing the best one for you based on cost, labor costs and reliability will not be difficult. Whatever method you choose, the main thing is that it retains as much heat as possible in your home.
Warmth and comfort to your home!
