How to understand that the window seal was worn out

The minimum life of the sealing rubber is 5 years. And with proper care, it serves for 10 years. If problems appeared earlier, it is better to adjust and pull up Accessories. Only if it does not help, you need to proceed to replace the gum on plastic windows. There are several basic signs of wear:

• In the cold season, condensate appears on the profile around the opening flaps.
• On rubber Tape There are visible defects: dents and cracking of the surface layer. She became tough and lost elasticity.
• There are signs of depressurization. The room is quickly played, and with strong winds from the River blowing.
• In the frost on the windowsill or the frame itself, ice is formed.
• The noise insulation level has decreased. You clearly hear the sounds of passing cars and talk people on the street. With strong wind, an elevated hum and even whistle appears.
• Due to high humidity near the glamorous, the foci of fungus or mold appear.

If there is no possibility to call the masters for diagnostics and repair, the first thing you can make your own hands is to lubricate and translate adjusting pin to the "winter" position. If nothing changes, move to the replacement of the rubber itself.

What better to put sealing gum for PVC windows

In the construction market or in the supermarket you can find different types of consumables. But the only correct solution is to install the elements recommended by the manufacturer of profiles. If you do not know the brand, it can be installed by:

• contract for acquisition or installation;
• engraving on the handle;
• logo on the front side of the profile;
• climbing on belt fittings;
• Marking on the end of the profile.

Marking on profile

If it is not possible to find out the manufacturer's company, it is enough to cut a piece of rubber ribbon for the sample. Take it most convenient in the place of the junction, which is in the upper part.

On one type of profile system, different types of rubber seals can be standing. So that you can choose the appropriate option for yourself, consider their classification in more detail.

By type of material

The raw material used directly affects high-quality characteristics. A good sealing gum remains elastic in the cold, retains shape at high temperatures and is not cracking under the scorching sun. It regularly serves as much as the manufacturer is declared. The market presents several options:

• Rubber. Produced from vulcanized rubber. It is cheap, but in the frost can lose elasticity, and under the influence of the sun crack. To prevent this, chemical additives are introduced into the composition. This means that physical properties depend on the production technology.
• Synthetic rubber (EPDM). Depending on the vulcanizing component, sulfur and peroxide EPDM are isolated. The first can leave yellow traces on white plastic. The second is slightly more expensive, but more practical. Both options have excellent physical indicators.
• Thermoelastopolymer (TPE). Made from modified PVC. They are very elastic, but poorly withstand deformations in the cold. Used primarily in deaf window blocks.
• Silicone. The material is very soft, durable, retains its properties in the wide range of temperatures, is able to transfer the aggressive impact of household chemicals and does not crack under the sun. The only drawback is a high price. It was because of it that products were not widespread.

By constructive execution

Allocate two options:

• Petal. They are a rubber ribbon, the outer part of which is made in the form of a curved petal, usually semicircular shapes. The reliability and durability of such consumables directly depends on the elasticity of the material. If he is dubing in the cold or poorly restores the form after compression, the blowing will immediately appear.
• Chamber. They are harness, along which one or more closed aircases are located. Due to the ribs, such products are better and longer hold the form. The air layer provides additional thermal insulation of the node of the gun. Similar seals are designed for window blocks of increased energy efficiency.

Best of all when replacing sealing rubber on plastic windows Use a regular type of consumables. If you want to change it, it is important to choose the thickness of the thickness. When the seals turn out to be thicker, accessories are very wear. If they are thinner, you get an insufficient entrance.

At the place of installation

Eliminate frame and shaft window seals. Mounted them on the frame and sash, respectively. Manufacturers recommend using both types of products. They differ in geometry and allow you to achieve maximum sealing between the street and the room. It is important to use the products of one brand and thickness.

For the convenience of installing, many installers use one type of rubber seal - Clause. This option is allowed. It allows you to avoid confusion and errors during installation.

Universal tires are on sale for sealing window blocks. It is better to use it in extreme cases if nothing more suitable has been found.

How to change the gum on plastic windows yourself

The replacement process is quite simple. But there are a number of features. We give three important rules, the non-compliance with which leads to purges, and in some cases damage to the accessories:

• Remove the sash before changing the seal. The features of the design of the upper loop greatly limit access. It is possible to physically replace the rubber tape without removing the sash only with a swivel-folding opening. But it's not every professional to cope with such a task. Therefore, for the rule, we accept dismantling of the opening part.

Leave a fragment of the tape, which is behind the top loop without replacement is not allowed. He is always thinner than a new sealing gum. Therefore, blowing appears in the corner.

• Change both sealing circuit. Thickness new and old seals are always different. Attempts to save in the end can cost more They end in the fact that one contour is adjacent to the frame, and the second will be several millimeters from it. This prevents the complete sealing of the gun. A condensate is formed between the profiles, and in winter ice.
• Glue rubber at the jock. The new seal during shrinkage dries and decreases in size. If you do not glue it, a slot appears on top over time. Attempts to squeeze the ribbon and put it with a stock rarely end with success. When the reheast turns out to be less necessary - the gap appears. If it is more - the "harmonica" is formed.

These are just the most common mistakes. Consider the stages of the main action plan.

Dismantling of the window sash

Change the seal contour is easier when the movable part of the frame is in a horizontal position. Therefore, before shooting it, you need to prepare a working surface. It is important to lay the frame on the external profile, not on the glass. In some cases, you need to first remove the handle. We carry out the work when the window is closed in the following sequence:

1. Remove the decorative top of the top loop.
2. To use the locking finger with a thick screwdriver or pliers and pull it down. If access is restricted below, first davir on protruding part of the rod.
3. I pull the sash and remove it from the loop.
4. Rim up the window up, removing from the bottom finger.
5. We put it on the prepared surface with a seal up.
6. We take the loop above the sash and delay yourself to reveal the "scissors".

Window glass windows are very heavy. If you have to remove a wide frame or you make this work for the first time, be sure to invite a partner.

For clarity, the removal process and installation will be demonstrating on the video:

Replacing sealing rubber on plastic window

The bog of the gum is in the upper part. It is from there that it is more convenient to start dismantling the old sealing tape. If the edges are glued to the frame, a knife or scissors, we use the seal anywhere and pull out from the groove throughout the perimeter.

The remaining pollution profile can interfere with sealing. We remove all the dirt with a luster or sponge with soap solution. The remnants of the adhesive remove the mechanically stationery knife or scissors.

The new shadow seal is beginning to insert from above, bypassing the entire perimeter. The shape of its legs is symmetrical, which allows you to insert a spike in the groove of any of the sides. In order not to make a mistake, remember how the old seal was installed. With the right installation, its wide party should pass exactly along the outer edge of the fixed part of the profile. It is important to avoid excessive tension of rubber elements in the corners.

After the passage of the entire perimeter, we cut the ribbon of jack. Give both its edges from the groove, dripped on the leg universal glue "moment" and insert back.

Replacing the sealing gum on PVC-frame

The principle of work remains the same, but there are a few differences:

• For ease of dismantling, rubber is starting to remove from the corner.
• It is preferable to use a frame tape. It is her that it is recommended to install all manufacturers.
• Rubber must be oriented with a wide face inside.

Seals TPE and VMQ types are changing from the angle to the corner. This means that they need to be cut, and not bend. At the same time, each joint is sizing the "moment."

For greater clarity, we will demonstrate the replacement process on the video:

How to care for plastic windows

Timely holding of preventive measures extends the service life of products in general. At the same time, blowing excluded in the places of the gun. Service is best to spend twice a year: in spring and autumn. Usually, the hostesses combine these operations with washing glass.

In the spring thoroughly rub rubberized elements with a rare or sponge, moistened in warm soapy water. Pay special attention to the lower part. There is most of all dirt. After all, even minor accumulations of dust disturb the tightness of the action. After removing the mud, the surface becomes softer and elastic.

In the fall, all the elements are repeated. Clean rubber surfaces are processed by special silicone lubrication. It additionally protects the material from the temperature drops and the scorching sun. Due to the formation of the oil film, the ribbon does not face the plastic in the winter, and the frame easily opens. Rassengers of rubber due to icing are excluded.

Instead of a special silicone lubricant, some hostess use cream for hands. Present in its composition moisturizing components become worthy substitutes for technical oils.

Now you know how to replace the sealing gum on the plastic window and carefully care for it. It helps to keep a comfortable microclimate in the house and prolongs the service life of the window block.
