Self-adhesive foam rubber for insulating windows. Self-adhesive foam tape for window insulation

Currently, self-adhesive insulation has gained high popularity. The reason for this was the properties of the material. It is also worth noting the wide scope of application. It can be used to insulate windows, pipes, walls and other surfaces.

According to reviews, the increased demand for self-adhesive insulation, the price of which depends on the thickness, width and length of the sheet, is also explained by the fact that it can perform two important functions at once: sound absorption and sealing. This material prevents the formation of drafts, freezing and other things. No less important property is the ability of the insulation to absorb moisture. Thanks to its use in construction, heat exchange is normalized, which guarantees maximum efficiency.

What types of self-adhesive insulation are there? What is its main purpose? How to install correctly? It is to these questions that we have to find answers in this article.

Types of insulation

Currently, insulation material comes in the following types:

• self-adhesive;
• roll;
• foil.

The easiest to install is self-adhesive insulation. For its manufacture, different materials can be used, such as:

• polyethylene foamed with foil;
• penoplex;
• foam;
• rubber.

Other manufacturers create less effective options. Use penoplex in pure form there is no point since it does not produce any result. And the reviews confirm this.

Insulation tape

Paper-based insulation is often used for windows. Such models are sold almost everywhere, they are quite popular. Before tape material was invented, regular paper and soap were used. Essentially, this insulation works according to the same scheme. But because there is adhesive layer, you no longer need to use soap. Often foam rubber is placed under such tape.

Foam insulation

Foam rubber insulation is used to ensure maximum sealing. It is also capable of compressing quickly and to the maximum without harming the surface in any way. Foam models are not only easy to install, but they are also much cheaper.

Insulation film

The last type of insulation is film, which is needed in order to minimize the escape of heat from the apartment through cracks in the windows. As a rule, it is placed only on one side. It should be installed using metal spraying. The insulation should “look” towards the street.

This film can not only protect against heat loss, but also perfectly retain solar color. It is better to use it in conjunction with another insulation option, then complete thermal insulation will be achieved.

All self-adhesive insulation can be easily installed independently; this does not require the help of professionals. A separate advantage should be noted that they all have decorative finishing. This means that there is no need to create a special quality during installation.

If we are talking about a roll or tape model, then on them protective films The installation plan is drawn in detail. That is why no difficulties should arise. However, you need to adhere certain rules during installation.

In order for self-adhesive foil insulation, the price of which is low, to adhere as successfully as possible, it must be applied to a clean and dry surface. In addition, it needs to be freed from stains and dust.

If necessary to paste roll material on a concrete wall, you must first use a primer. After applying it, the surface must be dried. When using insulation on brick wall plaster should be used. Immediately after it dries, it should be rubbed with sandpaper and then removed from dust.

There is no need to treat wooden coverings, the main thing is that there is no sawdust on them. You can cut the sealant with a knife or large scissors. Some insulation materials have a measuring grid, which allows you to cut the pieces as evenly as possible.

When using roll and tape models, you need to know that they are installed overlapping. If materials are used that have a thickness of more than 0.5 mm, then they should be mounted end-to-end. All cracks should be pre-glued with tape and foil.

Window insulation

Many people use cotton wool, newspapers, tape and foam rubber to insulate windows. But due to their properties, they are not able to protect the apartment owner from heat loss to the maximum. Moreover, in spring period Often these materials cause discomfort. Modern insulation materials can be used for both wooden windows, and for plastic ones. As a rule, self-adhesive material is most often used for windows. It has its own characteristics. For example, such material is capable of closing gaps up to 7 cm. When opening windows, self-adhesive window insulation does not interfere. Available for sale a large number of various colors, the models also differ from each other in size. Insulation materials can withstand moisture and temperature changes.

However, like any other material, self-adhesive insulation has its drawbacks. For example, it is short-lived, unable to withstand too low temperature conditions, and on modern windows, as a rule, it is extremely inconvenient to use.

Due to the fact that the adhesive coating is short-lived, the material is used once a season. It is possible to extend the period of operation, but then it is better not to open the window sashes. Even though the insulation can withstand temperature changes calmly, sharp frosts can still render it unusable. Because of them, the glue dries out and the tape begins to fall off. On modern frames it will not be possible to use self-adhesive insulation for windows (the price for it is 50 rubles/10 pieces), because they already have rubber bands over the entire area of ​​the window.

Door insulation

When it comes to doors, there are a large number of seals on the market that would be suitable for this purpose. Now there are many various options, which differ in thickness, height, width, purpose and material. They are used for wooden structures, and for metal ones. It should be noted that for interior doors and input seals should be used different materials. That is why this self-adhesive type device must be purchased carefully, carefully selecting what is really useful. If the door goes directly onto the street, then it is best to prefer options with a rubber base. Silicone and foam models will be excellent option for interior structures.

Self-adhesive insulation for doors with foil is considered the best option, since it minimizes the percentage of sweat heat. It is mounted on the inside of the door. First, you should completely clean the door from dust, degrease its surface, and only then glue the seal.

An important detail is that the foil layer should face where the heat source is, and not vice versa. If you glue the seal incorrectly, then there is no need to talk about preserving heat in the room. All the heat will constantly go into the wall. It will not be possible to accidentally mix up the sides, since foil is glued to the seal. Before purchasing, you need to pay attention to the shelf life of the material, its shape and condition. Maximum preference should be given soft options, since hard ones will interfere when working with the structure.

Finally

Rubber insulation and foil products are useful for sealing windows, doors and other cracks as tightly as possible. Judging by the reviews, they will be able to fully provide protection from the cold. Porous rubber will help improve thermal insulation. What nuances need to be taken into account when using insulation?

• Use this material window type recommended only in winter time of the year.
• Be sure to follow all rules of use and installation, for example, the material must be glued to a clean and grease-free surface.
• When insulating a room, you need to use self-adhesive insulation with foil. In this case, it is necessary to leave a small gap between them and the surface. Then the material will hold up much better.

It should be noted that self-adhesive insulation is absolutely environmentally friendly and harmless to humans and animals. This material does not cause allergies.

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.

About insulation

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:

1. Wooden windows

First of all, insulation is required for old window structures for the following reasons:

• Previously, glass was secured to the frame with special putty. Over time, it dries out and becomes stained;

• the frames dry out, so cracks and gaps appear between the glazing bead and the glass;

• the sashes are deformed and are not held tightly to the frame.

1. Plastic windows

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:

• violation of window installation technology;

• distortion of the window structure due to shrinkage of the house;

• factory defect of window design;

• mechanical damage to structural elements.

Types of insulating tapes

The widespread use of tapes for insulating windows is explained by a number of reasons:

• no annual replacement required;

• insulation is carried out in a short time on your own;

• there is no dirt when pasting, since no water is used;

• no traces of adhesive remain on the frame;

• there is no diffusion of the adhesive layer with the frame paint.

But this method of insulation also has disadvantages:

• after gluing, you cannot open the window sashes;

• poor-quality or poorly glued tape lags behind the frame in small areas.

Construction stores offer two types of tapes, which differ in the installation method.

1. Pasting

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.

Foam rubber tapes were the first to be used. Their popularity is explained by a number of advantages:

• high compression ratio;

• the frame does not collapse in places of insulation;

• low cost;

• high protection efficiency.

Such tapes have negative qualities:

• insufficient efficiency for large gaps;

• short service life. Effective during one winter season;

• in cheap models, the adhesive tape does not stick well;

• low resistance to water.

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.

1. Sealing

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:

• gaps up to 0.7 cm are blocked;

• withstands any temperature changes;

• It is possible to choose a color to match the color of the frame;

• the use of the window is not limited;

• affordable price.

But most of the disadvantages relate to adhesive tapes:

• not suitable for all window designs;

• when temperature changes, the adhesive layer is destroyed;

• with frequent deformations, peeling occurs in the glued places;

• The foam tape quickly gets wet and dust sticks to it. For this reason, frequent replacements are carried out.

Tubular seals are checked annually. If necessary, individual fragments are replaced.

As a rule, a tape is selected based on three indicators.

By material

Main advantages:

• low cost;

• high elasticity, allowing you to close gaps of different sizes.

There are also disadvantages:

• Due to the porous structure, moisture is quickly absorbed. The drying process takes a very long time;

• low durability. With prolonged use, the material turns yellow and crumbles.

Unfortunately, such tapes are rarely used for window insulation, as they increase the cost of window construction by up to 15%.

1. Rubber― used for the manufacture of two types of tapes: self-adhesive and sealing.

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.

1. Polyurethane foam (PPE)― porous material made of foamed polyethylene.

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.

By manufacturer

You can find tape in hardware stores different manufacturers.

However, only materials from the following brands are in demand:

• Russia - Profitrast, Economy, Zubr.

• Germany - KIMTEC, Deventer.

• Poland - Sanok.

Domestic manufacturers, as a rule, work using European technologies and produce quality material no worse than foreign models. At the same time, German and Polish ribbons, although more expensive, last longer.

By cost

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 for Russian material you need to pay up to 15 rubles, and the most expensive German rubber insulation will cost 50 rubles.

Features of preparing windows for insulation

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:

1. Everything is removed from the windowsill. The blinds are removed from the window.

1. The frames are washed with soapy water and then dried. The tape requires a dry and grease-free surface.

1. The glass is carefully inspected. Wooden windows may have cracked glass. They must be replaced as they are a source of heat loss.

1. Grooves are prepared for the sealing tape. They should not contain old tape, dirt or paint.

1. Before starting work, they determine the places where cold air comes from the street. They are insulated first. Weak spots- these are sashes, slopes, window sills.

Insulation with adhesive tape

The insulation technology is not very complicated. First of all, it is necessary to follow the sequence of work.

1. Plastic windows

Insulation is carried out in the following sequence:

• pre-removed old insulation is used, firstly, to purchase similar material, and secondly, to pre-cut the old material to size.

• gluing begins from the top of the window. As you progress, it is removed in small sections protective layer, and the tape is pressed tightly.

More details in our video:

Important!

1. The pasted tape should not have many tears.

2. In the corners the tape is not cut, but wrapped.

1. Wooden windows

For these windows, in addition to adhesive tape, thin foam rubber is often used. The work is performed in the following sequence:

• strips of foam rubber are cut along the window opening;

• cut foam rubber is placed between the frames;

• The tape is cut to the size of the window;

• The tape is applied with a sticky layer to the foam rubber and smoothed with a napkin.

This insulation will last up to three years. But it’s better to do it as shown in the video:

Insulation with sealing tape

1. Plastic windows

Typically, plastic windows lose heat for two reasons:

• breakdown of fittings;
• seal wear.

Correct installation of the tape increases the insulating ability of the window. The following sequence of work is recommended:

• before installation, the tape is kept at a positive temperature, since this affects its expansion inside the groove;

• The tape is cut to fit the window. The joints are cut at right angles. For thermal expansion a stock is created: for every meter 1 centimeter of material;

• The tape is pressed into the groove with a spatula, and the adhesive strips are removed in small sections.

Important!

1. In the corners of the frame, the tape is connected only end-to-end.

2. To prevent impregnation from leaking out, the tape is not compressed more than the permissible value.

After installing the sealing tape, the locking mechanism is adjusted: the pressure is changed by trunnions, which are located at the end of the sash.

Adjustment is made with a hex wrench. The pressure increases when the trunnion head is installed in a horizontal position.

1. Wooden windows

The Swedish method of insulating such windows using EuroStrip technology is in great demand. It has the following advantages:

• there is no need for annual window insulation;

• after ventilation, the tightness of the windows is not compromised;

• frame service life increases;

• high degree of protection from dust and street noise.

For insulation, two types of tapes are used: rubber and silicone.

By the way, branded Swedish silicone seals are easily inserted into the groove and last up to 20 years.

Installation is performed in the following sequence:

• the sashes are removed from their hinges and inspected. Rotten areas are identified and then restored;

So, both types of window insulation tapes deserve attention. Which one is better depends on the condition of the window.

If you choose the right one, the insulation will quickly pay for itself, and the apartment will always be warm and cozy.

To constantly enjoy a comfortable microclimate at home, you must use high-quality insulation for windows. Self-adhesive varieties allow you to carry out the thermal insulation procedure in the shortest possible time. Next, we will consider the most popular models today.

First of all, let’s highlight the main advantages characteristic of all self-adhesive window insulation:

• Easy to install. Of course, this is the main advantage due to which this technology has become widespread. To glue the strip you won't need any tools (except for a knife to cut a piece if necessary). The work can be done on a surface of any shape.

Important! The strip does not need to be secured with a strong tension, since temperature deformation must be taken into account.

• Functionality. They are suitable for all types of windows (wooden, plastic, aluminum).
• After installation, such material will be practically invisible, which gives more decorative possibilities. In this case, the strip can be exactly matched to the color of the profile.
• High elasticity, due to which the seal does not interfere with closing.
• Physical features allow you to create favorable air permeability of the room. This has a positive effect not only on people, but also on indoor plants.
• High temperature resistance. Minimum operating range: +45 to −50 degrees (depending on the specific model). In regions that are too hot or cold, such technologies cannot be used. The exception is silicone analogues, which have a wider temperature range.

There are also quite significant disadvantages:

• The main disadvantage is the extremely short operational period. As a result, it becomes necessary to update the seal every few years. This incurs financial and time costs.
• Weak physical stamina. As a result, such models begin to wear out quite quickly, especially for foam rubber varieties.
• The need for preparatory work during installation. Before applying the sticker, you will need to thoroughly clean and degrease the original surface.

In general, such window insulation can be recommended in cases where high installation speed is required and there are no critical conditions (for example, winter temperatures below −45 degrees).

Let's look at the main varieties and their properties

Next, three categories will be considered: EPDM, PVC and silicone. You can find other varieties in stores, but they are no different high quality, and using them will only waste time. The use of foam rubber models seems especially pointless - they wear out in 1 season.

Affordable and inexpensive option - PVC

Such models are most often used by window manufacturers, since they are the most available material. Nowadays TPE is mainly used - an improved modification of PVC. Such models are extremely convenient to assemble, as they can be given absolutely any shape.

In terms of its performance characteristics, this is the worst option among those we are considering. At low temperatures it begins to crack, and at high temperatures it begins to melt. Therefore, it is not recommended for use in regions with harsh climates. But TRE holds up well physical exercise(when opening/closing the doors). In general, such technology can only be recommended as temporary.

Modern and practical analogue - EPDM

Ethylene propylene rubber has replaced plastic. Possessing higher performance characteristics, it immediately began to gain popularity. Key properties:

• Higher temperature range: from −55 to +100 degrees. It cannot be used only in the regions of the far north.
• It is not at all afraid of UV rays, even in hot regions.
• Moisture-resistant, therefore does not lose its properties as a result of constant exposure to precipitation.

This model has few disadvantages: the presence unpleasant odor(if we are talking about sulfur varieties) and the increased price of color options (this is due to production technology). In general, EPDM could be called ideal solution, if not for the presence of silicone, which is more perfect in every sense.

Best of its kind - silicone

Today, this is the most advanced analogue that surpasses its competitors in all respects. Main advantages:

• Temperature range: from −85 to +200 degrees.
• Does not wear out as a result of constant physical impact.
• Not afraid of any natural irritants (ozone, UV rays, precipitation, etc.).
• Thanks to high elasticity, maximum tightness is achieved and, as a result, best protection from the penetration of cold.
• Warranty service life is 10-20 years (depending on the manufacturer and the specific model). This is comparable to operational period window.

Its only drawback is high cost- it is 2 times more expensive than its previous “brother”. However, if we remember that the seal is only a couple of percent of the cost of the window, this factor fades into the background. Therefore, there is no point in saving on this aspect.

Someone continues to insulate the windows toilet paper or newspapers. But today there are a sufficient number of specialized tools designed to make our everyday life easier. It’s worth mentioning right away: pasting windows is a regular process and it will be repeated every winter. Therefore, it is worth choosing the least labor-intensive method of insulation. In this article we will look at the types of insulation for self-adhesive windows. We will also compare the cost different types materials and instructions step-by-step installation on one example.

Any self-adhesive insulation always consists of two main elements:

• Warming base;
• Adhesive layer.

The first is designed, in fact, to protect from the cold, the second eliminates the need to dilute and use a special adhesive. This tape-based approach has three significant advantages over traditional methods:

• Reduces insulation installation time;
• Simplifies pasting;
• Eliminates wet processes.

And as a bonus, any adhesive will leave marks on the frame when the owner wants to get rid of the insulating tape. Using special adhesive tape for insulation will not cause diffusion between the frame paint and the adhesive composition of the insulation.

Let's now look at the 4 materials from which self-adhesive window seals are made, and discuss the advantages and disadvantages of each.

Materials

Foam rubber

Foam insulation has been used since Soviet times. You may remember people taking backing from an old chair or armchair, cutting it into strips and inserting it into window cracks to seal it. Today there are foam rubber based special options for insulating windows. The advantages of using such material are

• Low cost;
• Elasticity - can be used in cracks of different thicknesses.

Of course, there are also disadvantages. For example, foam rubber perfectly absorbs moisture. This occurs due to the porous structure of the material. After just one soaking, such insulation will take a very long time to dry.

This material is also short-lived. After prolonged use, the foam crumbles and turns into dust.

PVC

Insulating tapes for windows and doors made of PVC or polyvinyl chloride have greater strength than foam rubber, but all of them cannot be called the very best in our comparison.

Rubber

Self-adhesive rubber seals are actually made from synthetic rubber. The abbreviation EPDM is used for marking.

Materials made from rubber will serve well for a long time. Some manufacturers claim that such self-adhesive insulation can withstand a temperature difference of -50 - +100 degrees. You shouldn’t test this in practice, but the rubber insulation will definitely withstand -40.

PPE

Materials made of foamed polyethylene have a pleasant to the touch, porous structure. Insulation materials are very elastic. This property allows them to be used especially in small window gaps. Foamed polyethylene differs from ordinary polyethylene in the presence of more air in its structure.

Air is the best thermal insulation medium. If you do not plan to heat your windows to temperatures above 120 degrees, PPE insulation will be safe. Only at such a high temperature will it turn into a liquid mass, which can be toxic. Up to the specified limits, foamed polyethylene does not react.

Manufacturers

Having made a short review of the materials from which self-adhesive window seals are made, let's pay attention to specific manufacturers. Of course, in reality there are a huge number of manufacturers, but most likely in the store you will find insulation from one of the following brands:

• Profitrast;
• Econ;
• KIMTEC;
• LLC "SV-Forum LLC";
• Bison;
• Deventer;
• Sanok.

Some of them are domestic, for example, Zubr, and some, for example, KIMTEC or Deventer, are foreign-made. It is preferable to buy insulation made in Germany or at least in Poland. They live much longer, although they are significantly more expensive. By the way, about the cost a little lower.

Cost table

Self-adhesive insulation is sold wholesale and retail, as well as in coils (large skeins) and in small packages for private use. Below is comparison table, which will help you see the approximate cost of 1 linear meter from different manufacturers and from different materials.

Manufacturer	Country of Origin	Cost of 1 linear meter	Packaging cost	Length (meters)	Insulation model	Material
Deventer	Germany	42	250 rub.	6	S7256	EPDM
Profitrast	Russia	10	90 rub.	9	Standard, Profitrast	PVC
Economy	Russia	3.6	44 rub.	12		PVC
KIMTEC	Germany	12	18 rub.	1.5		EPDM
AVIORA	China	8.2	82 rub.	10		Foam rubber
-	Russia	3.9	39 rub.	10		PPE
Scotch tape for window insulation	Russia	2.84	142 rub.	50

It is clear that German insulation for windows made of synthetic rubber is the most expensive. Although their price is within reach. 40-50 rubles per linear meter is not so much, considering that one window requires 3-5 meters. You can insulate all the windows in an apartment for about 2,000 rubles.

How to stick

So, you have chosen and bought self-adhesive insulation, how to glue it to the windows? Remember at the beginning we said that the adhesive layer makes installation easier? So, this is actually true.

• If there is one, remove the old insulation by prying it with a knife;
• Clean thoroughly work surface frames or glass. You may need a rag or brush for this. Sometimes the remnants of old glue need to be removed with a knife or sandpaper;
• Degrease the surface with an alcohol solution;
• After the surface has dried, remove the protective tape from the purchased insulation;
• Gently press it against the frame or glass.

Remember, the tape will be completely glued only after 2 hours.

Most often, old windows need insulation. If metal-plastic windows require insulation, most likely, you should start solving the problem by replacing the sealing rubber bands. This procedure will give a much better effect than simply gluing materials at the joints. This is due to the fact that the seals inside the frame prevent air from blowing in. While self-adhesive only prevents waste warm air from the premises.

Window pasting is a temporary measure in cases where it is not possible to thoroughly insulate the window openings. And yet, if you decide to insulate your windows this way, I hope the article provided enough information. If you have any questions, please leave them in the comments.

Just 5 years ago, old ones were used to insulate window frames. old-fashioned methods: newspapers, strips of fabric, cotton wool, melted paraffin, putty or tape for insulating windows. However, this approach was not convenient and effective - a small draft still remained, and it was very difficult to clean the frames after winter.

Attention! Windows in residential premises must be well insulated - this is one of the the most important conditions maintaining heat and avoiding drafts, which are hazardous to health. Poor quality insulation can lead to large losses of thermal energy (up to 50 kW per day).

Fortunately, the modern construction market offers many innovative materials for insulating windows. All of them have excellent thermal insulation and aesthetic characteristics, as well as ease of installation.

Self-adhesive tape - everything you need to know

Of the entire range, I would like to highlight self-adhesive window insulation. It is produced from various materials such as foam rubber, polyvinyl chloride, polyethylene foam and rubber.

On one of its sides there is a sticky compound, protected with paper tape. When pasting this insulation the protective paper is removed.

Positive and negative points

The advantages here include the fact that the self-adhesive seal for windows:

• allows you to close gaps up to 7 mm;
• Available with a profile in several variations (more on this a little later);
• does not deteriorate from temperature changes and moisture;
• does not interfere with the opening and closing of windows;
• manufactured in several color options (white, light brown, dark brown and black), which makes it not so noticeable against the background of the windows;
• you can easily stick it on with your own hands, without anyone’s help;
• The price for these products is quite affordable.

Of course, self-adhesive tape for window insulation, like any other material, has its drawbacks:

• fragility (such window insulators are suitable for use only for one season, less often - two);
• at very low temperatures, the adhesive ability of the insulation is significantly reduced, which soon leads to its peeling off from the frame;
• carry out insulation plastic windows or insulating a loggia with a double-glazed window using this adhesive tape is not possible (Find out also,). Otherwise, you can cause damage to modern window structures, in particular the opening and closing mechanism. But for wooden openings insulating tape for windows is an ideal option!

Before sealing window frames with self-adhesive insulation, you need to decide on its material and profile. We cannot recommend any specific material to you, since each of them has its own positive and negative sides.

However, several useful tips Let's give it anyway:

1. If you prefer rubber duct tape, then buy the softest one. In this case, it will evenly fill all the cracks. But hard insulation will not compress well, and the cold will blow in.

Foam self-adhesive insulation with a rectangular profile

1. Foam rubber, polyethylene foam and rubber tapes with a rectangular profile are perfect for sealing even cracks measuring 1-4 mm. But if the cracks in window frames not even, it is better to buy insulation with a profile similar to Latin letters:

• C and E are best used for gaps of 1-3 mm;
• P and V – for gaps of 3-5 mm;
• B and O – for cracks 3-7 mm.

Note! Foam rubber insulation is also sold in the form of self-adhesive strips, for gluing which you just need to remove the protective paper and press it tightly to to the right place. Although the effectiveness of this material is not very high, foam rubber allows the windows to “breathe”.

1. When choosing self-adhesive insulation, do not forget to look at its expiration date. Window insulation tape with an expired or nearing expiration date will quickly peel off from the surface, or will not provide proper thermal insulation at all.

1. No less important nuance– quality of tape window insulation. To check it, bend the product and evaluate how quickly and accurately it returns to its original shape (see also article).

Installation of self-adhesive insulation

Thermal insulation is performed at the highest level!

First of all, before thermal insulation of windows, you need to prepare the surface on which the insulating tape will be glued.

Here step-by-step instruction all work:

• Check frames and glass for cracks. If there are any, then it is imperative to replace the damaged elements.
• Remove the old insulation (if there was any).
• Wash windows from dust and dirt.
• Then degrease them with acetone or alcohol and dry thoroughly.
• The insulation must be glued at temperatures above +5ºC, but not more than +40ºC.
• Measure the length of tape required for the entire surface and begin fastening it along the entire line of contact between the window sash and the frame.

Important! The insulation must be glued in one piece, without cutting it at the corners of the sashes. This is necessary in order to thermal insulation material did not allow the cold into the apartment. It is better to cut it slightly at an angle of 45º.

• Remove the protective paper gradually as the seal adheres.
