From the life of sealing gum

Plastic windows are a single mechanism, all the details of which are important and carry their functional load. Window seals are used to seal the sash, protect the house from noise, moisture and cold air. Old, cracked gum may cause blowing.

Regardless of quality window profile and equipped with window fittings, low-quality or deteriorated from time to time, the window seal can negate all efforts to adjust the window for blowing.

In the photo taken with an infrared camera, you can see that the coldest places of the window are the corners of the sashes. In this case, "bumps" appeared in the places where the seal was folded - the consequences of the stretched sealing gum.

First of all, the external window seal fails, as it is subject to external atmospheric influences. But there are exceptions, for example - repairs were made in the room. Construction dust, all kinds of vapors of paint, varnish, solvents, etc., lead to the drying out of the seal and the loss of its elasticity, which, in turn, leads to the loss of the tightness of the window.

However, both sealing circuits (on the frame and on the sash) must be changed. If only the outer contour of the seal is replaced, the pressure of the inner one will be significantly weakened.

The need to replace the seal can be caused by the following factors:

Defects of seal rolling are especially noticeable in the majority of Moscow new buildings. Large volumes of work, initially low quality of windows and repair and finishing work in the room - all this leads to the fact that sometimes at the time of transfer of the apartment by the developer, the replacement of the window seal is already required.

An experienced foreman of our organization will replace the seal of plastic windows manually, without stretching the elastic, after pre-processing seats, which excludes the formation of "bumps" on the window seal.

How to understand that the window seal has become unusable?

A suitable seal has saturated color, it is soft and elastic. If you see that the gum has dried out, cracked or "bumps" have appeared on the corners - it's time to replace the seal.

Caring for rubber seals

Modern seal for plastic windows made of synthetic rubber EPDM is designed for 9-11 years of use. However, this figure is given taking into account the correct factory installation, average load and timely maintenance. If the conditions are not met, the service life can be reduced to 5 years.

Therefore, twice a year, the surface of the window seal must be wiped with a damp cloth and treated with silicone grease, which forms a highly elastic film on elastomers (APKT, EPDM) and is water-repellent. Alternatively, you can use glycerin (available at any pharmacy).

With regular maintenance, the replacement of the plastic window seal can be delayed by 5-6 years.

In addition to the service of replacing the seal, you can order from us a set for the care of windows made of solid white PVC, which includes grease for plastic window seals.

Myths about seals

In conclusion, we give the following analogy: no matter what good refrigerator or Washer, the seals that have fallen into disrepair will call into question the reliability and practicality of the entire mechanism.

Note: there is a program of discounts for pensioners to replace plastic window gaskets.

Currently, plastic windows have gained well-deserved popularity among the average man in the street. When installed in accordance with GOST, correct operation and appropriate window care, they are able to delight and protect the inhabitants of the home from noise and dust for more than a dozen years.

However, sometimes not everything goes smoothly when using these PVC products. Forgetting about proper maintenance, a person who has installed even from well-known manufacturers sometimes encounters the unpleasant consequences of his forgetfulness: moisture begins to seep into the room through the window opening, dust penetrates, and the wind blows out.

The reason for this, in all likelihood, is the worn-out seal installed in the window structure. To correct this situation, it is enough to replace this product. To do this, you do not need to call a specialist, the average man is quite capable of replacing the seal on the windows with his own hands.

What is a seal. Concept and purpose.

To make a replacement, you need to determine its location. To do this, you need to know what it is (see photo above). So, a window seal is a special rubber layer with a relief structure.

Its fixation is carried out in small grooves inside the plastic structure. The sealing material is located around the perimeter of the entire window. With appropriate periodic maintenance, it must withstand Negative influence too high and low temperatures, do not let heat, cold, moisture inside the room, while simultaneously maintaining an optimal microclimate in the living space.

There are several types of similar materials used in modern window designs. The most common of these are rubber and rubber. The advantages of each are low sensitivity to temperature extremes. On top of that, they are quite resistant to mechanical damage.

In addition to the two types of seals listed above, there are also polyethylene and polymer. The polyethylene seal comes with foam filling. Its features are poor shape recovery after prolonged compression.

In the production of a polymer sealant, the structure is close to the material from which the profiles of modern plastic windows are made. The advantage of the characteristics of the polymer seal is that its installation in the window construction provides a good tightness of the structure as a whole. Wherein given view The sealing material can lose its original elasticity due to the influence of temperature changes and the influence of ultraviolet rays.

When do you need to replace the seal?

Heat map of the window. The place of the worn-out window seal is marked in blue.

As mentioned above, the seal is designed to seal the plastic circuit, either. Its role in the window structure cannot be underestimated - it is responsible for providing sufficient sound insulation, protecting the room from specific odors that tend to penetrate the window opening and a number of other factors. A person who spends a sufficient amount of time in an apartment is not difficult to understand when it is necessary to change the seal to plastic windows... This may be evidenced by one or more of the cumulative factors listed below.

• signs of depressurization of a double-glazed window;
• the formation of condensation on glasses (especially in the corners). About elimination this effect there is an article called "";
• ice formation in winter, both on the glass and on the windowsill;
• excessive penetration of street noise, or cold streams into the room;
• the appearance of fungus and mold on the seal;
• manifestation of signs of cracking of the material.

Selection of the type of sealing material.

If a profile is installed from renowned manufacturer, regardless of whether it is a plastic product or, it will not be difficult to purchase a suitable seal. However, if the profile system is mounted less than famous brands, then before finally deciding on the choice of the future sealing layer, you need to know the specifics associated with the interchangeability of certain window elements.

Most of the profiles from little-known companies copy the products of the true industry leaders in the sale of window products:, etc. That's why individual elements, including sealing - interchangeable... For example, the less common brands Proplex, Vitrage, Novotex are focused on one of the leading window market leaders - the KBE brand. The sealant of the REHAU brand can be successfully used in the structures of the manufacturers Montblank or Brusbox.

Online stores, like regular ones, are sales-oriented building materials, sell this product, both in large quantities and in an amount sufficient to repair one window. This flexible attitude towards the customer allows the latter to easily select and order the required amount of sealant. The main thing when ordering is to know exact dimensions constructions and add 20% to them for the stock.

An important point when ordering and buying a seal for windows on your own is the fact that the thickness of the new layer should not exceed the thickness of the old one, otherwise there may be problems during the installation and further operation of the window structure.

Also, when buying a sealant to install it in a window with your own hands, you do not need to save. , although its cost is not high, it makes no sense to apply it in PVC windows- it is only suitable for sealing wooden windows sample of the times of the USSR. Modern plastic structures need a special seal made in accordance with the requirements of GOST 30778-2001. So choose carefully suitable material before proceeding with its own installation.

How to increase the service life of a seal?

Instead of spending extra money on the purchase and effort to install a seal in the window, it is better to pre-empt possible problem... To prevent premature wear, the sealing product needs periodic maintenance:

• At least twice a year it is necessary to take care of the windows - washing and wiping. This also applies to the sealant.
• Depending on the climatic conditions, to prevent cracking, periodically apply to the sealant either glycerin, sold in every pharmacy, or a solution in which silicone is present.
• it is better not to use detergents with a high fat content in order to exclude the possibility of penetration of a fatty substance into the structure of the seal.
• When conducting renovation works, or work with an increased dust content in the air, the window is best kept closed... This will prevent small particles of dirt and dust from settling on the seal.

Replacing the sealing cord with your own hands.

If you have to replace the gasket yourself, then you need the following tools and materials:

1. Scissors.
2. New matching seal.
3. Silicone glue.
4. Glue gun.

Important!
To carry out a high-quality replacement, it is necessary to lay a solid sealing material around the entire perimeter of the window, without a set of length by its individual components.

Knowing this, you can start replacing the old seal on the selected window. In order to perform all the necessary operations correctly and in the required sequence, the following sequence of actions must be observed:

• Using scissors or a utility knife, pry off the edge of the seal that needs replacement. With a little effort, you need to remove it from the special grooves in window frame.
• Wipe the freed grooves with a soft, lint-free cloth - this way the cord will better fix in the cleaned grooves.
• To fix the new seal, it is necessary to pre-prepared silicone glue grease the corner parts of the frame.
• With the utmost care, insert the new material to be installed into the corresponding recesses. The tourniquet should run around the entire perimeter of the window.
• The excess is trimmed with scissors.
• The joint joint of the two ends of the seal is carefully glued in the corner of the window frame.

- a thing is not eternal. They serve for a long time and regularly, especially when used correctly. The design of such windows practically does not differ from wooden ones, however, in plastic windows there is rubber compressor.

Many people think that the seal does not need to be changed, and if necessary, then only with a major replacement of the entire window. This is not true. When it comes to replacing the seal, it is important to understand that you can do it yourself or with the help of a master.

The call of the master and his work, of course, will be paid. Therefore, those who want to save money can do this simple procedure on their own. So, when do you need to replace the seal on the plastic window? Usually, replacement is carried out after wear and tear, and this is an average of two years, plus or minus a few months.

All sorts of unpleasant manifestations are observed on a window that is poorly protected with a seal. For example, if it rains heavily, water starts flowing out from the bottom of the frame, and if it is frosty outside the window, the seal also freezes. It is also necessary to replace the layer when the seal has changed its shape, has become uneven, is damaged, that is, its integrity is violated.

Poor sound insulation and a draft even with a closed frame can also serve as a sign of a faulty seal. Reasons for damage to the seal: temperature drops (difference in temperature outside the window from the inside), very coldy, improper care outside the frame as a whole, too high humidity.

To replace sealant, you only need three the subject is directly a new seal. which can be bought at construction markets or in hardware stores, glue and rubber scissors. The old seal must be separated from the window, and then the vacated space must be thoroughly wiped with a rag. Can be washed warm water with soap, but then wipe dry so that not a drop of water remains on the surface.

The old seal cord is removed completely, and a new cord is also inserted entirely in its place. The cord sits on a special glue, this must be done quickly and carefully until the glue has dried. The cord must not be cut, otherwise the whole point of installing a new seal will be lost. It is also necessary to monitor the cleanliness of windows, dirty windows wear out faster, the sealant wears out and deforms faster.

Reading time ≈ 3 minutes

Plastic windows are recognized as the most economical and reliable in terms of heat preservation. Special sealing gaskets located around the perimeter of the window frame help to ensure the preservation of heat in the house. Timely replacement of the sealant on plastic windows guarantees the absence of drafts and a decrease in the temperature in the room. The process of performing this work is quite simple, but it requires mandatory adherence to the sequence of installation operations, as well as care and accuracy.

Work order

The first thing to do is to examine the technical condition of the seal available in the window. It is a plait of a certain embossed section, made of the most durable, heat-resistant materials.

Initially, the sealant has a fairly high performance. For example, a German-made rubber seal will not require replacement and will regularly perform its functional purpose for 8 years. The Russian-made seal has a slightly shorter service life.

Even the slightest cracks on its surface, especially holes, damage, places of poor-quality connection with the surface of the window frame indicate the need to repair plastic windows and replace the seal as soon as possible.

Having picked up required view seal for your window profile, you can start installing it. They are divided into two groups: on the window frame and along the sash of the window itself. A high-quality replacement of the seal involves the replacement of both types at the same time.

You can familiarize yourself in detail with the process of replacing the seal on plastic windows if you look at the photo of the repair work.

1. Get started assembly work it is necessary, after removing casement from its place. This is not difficult to do: tightly close the window on the handle, remove the outer cover from the upper canopy, knock out the core and remove the frame. Now the window remains attached only to the lower canopy, from which it is easy to remove it by just lifting it slightly.

2. Place the window sash on the floor (or sofa) and remove the damaged rubber seal from its place. It is enough to pick up the edge and it comes out freely. In the area of ​​the upper hinge, you need to slightly raise the mount, since in this place the mount serves as a seal holder. Actually, for this it was necessary to remove the window.

3. Clean or wipe the freed holes from dust, all kinds of contaminants.

4. Place a new seal in the window groove similarly to the previous one along the entire perimeter of the window frame. Do not tighten the rubber of the seal, because as a result of temperature fluctuations, the rubber is compressed / stretched, which can lead to rupture of the one-piece seal strand.

Now you need to replace the seal on the window frame. The work plan is the same:

• remove the worn out material;
• cleans the place from dirt;
• insert the harness of the new seal into the prepared place.

Plastic windows have replaced the classic wooden ones, displacing them due to a number of advantages. Thanks to them, dwellings have become warmer in winter and cooler in summer, the noise of the streets does not disturb the atmosphere. home comfort, and the boys playing football in the courtyard ceased to cause anxiety among the hostesses. The rubber seal for plastic windows plays an important role, ensuring their functioning at the proper level. If you want to extend the life of your windows, then you should pay special attention to operation and timely replacement, this is a small but extremely important detail plastic profile.

What is a seal?

This is a layer of special material that runs along the perimeter in specially designated recesses for it. Outwardly, it resembles a parallelepiped-shaped cord with special projections for fastening. It is made from rubber, polymer material or polyethylene. Each of the types has its advantages and disadvantages, however, the most universal is the rubber seal for windows, it is ideal, due to its resistance to temperature extremes, high level sealing and durability.

Exploitation

With proper care, a rubber seal can last up to 10 years. Achieving this is not at all difficult - you just need to adhere to simple rules for care

• Clean the entire profile inside and outside at least 2 times a year: before and after cold weather;
• Thoroughly remove dirt accumulated during inclement weather with a sponge, soft tissue or an ordinary rag;
• After cleaning, a lubricant for rubber seals, or, in its absence, glycerin will be appropriate as a lubricant.

Do not use greasy detergents when caring for a profile - they can harm the tourniquet;
Do not cleanse in bad weather - there is a high probability of moisture ingress and the subsequent development of fungus, dampness and pathogenic bacteria;
Carry out repairs and other work in which the a large number of dust, at closed windows to avoid contamination of the profile from the inside.

Lubricants for rubber seals

Only use silicone grease for rubber seals. It is applied immediately after washing the profile, significantly increases the moisture-repellent properties of the window and protects its elements from corrosion. The principle of its operation is to create a thin layer of silicone, which covers the surface integrally with inseparable molecules and makes it more slippery, as a result of which the effect external environment decreases significantly.

It is forbidden to use VD 40 grease for lubricating rubber seals.

It also maintains the elasticity of the sealant, prevents mechanical damage and freezing during low temperatures... Prices silicone lubricants not high: from $ 3 per bottle. Agree, it's not such a big amount to extend the life of a window by 10 years. And given the universal nature of the lubricant, you can use it for your other mechanisms: door, bicycles, car parts, household appliances. The most common manufacturers on the market are SILICOT, LIQUI MOLY, CAR-REP, XADO.

How to improve the effectiveness of the seal?

You already have a high-quality sealant - a rubber self-adhesive tourniquet will perfectly help him in the fight for heat! They are very versatile (they can be glued not only on windows, but also on doors, wall corners), hold on for a long time, do not allow moisture and foreign odors to pass through. As a rule, they are mounted on top of the frame at the points of its joints with the walls or. When installing, follow this algorithm: clean the surface from dust, degrease it with alcohol or acetone; cut the seal to the required length; remove the protective layer, press the cord firmly to the surface and leave it for 2 hours.

How to replace the rubber seal?

Alas, the perpetual motion machine was invented only in the works of philosophers and science fiction novels. And the eternal seal is unreal even more so. Sooner or later, you still have to change it. This will be indicated by the following "symptoms":

• Frequent drafts;
• Dampness on the windowsills and walls adjacent to the window;
• The appearance of mold and mildew on the rubber parts of the window;
• The seal looks bloated, dry, and flaking;
• In winter on the frame or internal parts icing appears on the window.

Such signs indicate the expiration of the life of the part and that it simply does not withstand the loads exerted on it. In this case, a replacement is required. rubber seal... How to do it?

1. Purchase a new seal. If you have a profile from a well-known company (VEKA, REHAU, KBE), it will not be difficult to choose according to the design. However, when using third-party profiles, you should either consult with a specialist or try to find an analogue. So, for Virtage, Novotex, Proplex, KBE seals are suitable, and for Montblanc and Brusbox - REHAU;
2. Discard the old tourniquet. Using scissors, pry the edge off and gently pull it out of the grooves. Thoroughly clean the freed grooves so that the new cord fits snugly against them;
3. Apply glue evenly to the corners of the frame;
4. Insert the cord into the grooves and, without cutting, run it along the entire frame;
5. Remove unnecessary residues with scissors;
6. Cover the joint between the ends of the seal.

Do not be afraid of the myths that seals are sold only in huge kilometer coils. You can also purchase it at retail.

You should not buy a tourniquet wider than the original one. This will only swell and crack faster. For additional protection of the area with potential gaps, it is better to use the self-adhesive sealant described earlier.
