How to change the seal in plastic windows. Replacement of the seal in plastic windows

Every year, manufacturers delight us with the innovations of their products. A couple of years ago, it was difficult to maintain heat in the room, since the window frames were wooden with slots that had to be sealed with tape or insulate with cotton wool. All this is perfectly remembered because it was even done by children at school. But it’s good that progress does not stand still and facilitates our life. Now almost every home owner sets plastic profiles that do not let the heat out, but in the inside of the cold and dust. The old windows were required every year, but the plastic ones are not dispensed with proper care.

What is a new generation window and how to care for it

There are many constituent structural elements: slopes, drainage, window sill, fittings, graduates, sealing contours, double -glazed window and PVC profile. The principle of assembling windows developed by engineers makes it possible to make packages of any configurations.

Advantages of PVC systems:

• Strength and durability.
• Relatively light weight.
• Variant opening.
• Simple care.
• What the profile consists of.
• Frame - a box fixed in the opening.
• Sales - designed for partial opening.
• Impost - thanks to it, the box is divided into parts vertically or horizontally.
• Holding double -glazed window.

To date, manufacturers use noise -insulating glass, energy -saving with sunlight protection. The quality of the window depends on the accessories. If loops and other mechanisms work poorly, then they will create inconvenience to the user.

Sealing element in plastic profiles

If the sealing element has become unusable due to poor -quality material from which was made or uneven installation of the double -glazed window, do not worry very much - it can be replaced.

Where is he located? The sealing tape is a rubber product that is fixed in the small paths of the window frame and is located along the entire length of the structure. The main task is to ensure a tight fit of the double -glazed window to the frame in order to prevent the penetration of cold air from the street and warm outside.

Types of seals

In plastic profiles, different types of sealing element are used. The choice depends on the desire and capabilities of the customer. But the most used products are rubber and rubber. Both of them have a powerful resistance to low temperatures and the strength of the material is not so prone to damage.

Polyethylene has a foam and is poorly returned to the previous form after compressing, and polymer - characteristics of the profile itself are characteristic. This provides good tightness, but the properties that rubber and rubber owned are not available to them. They are affected by temperatures and sun.

In what cases it is necessary to replace the seal in plastic windows

Of all the above, it is already clear what is the role of sealing rubber. Damage to this component leads to depressurization and penetration into the premises of the smells from the street, sounds, heat leakage.

Determining unsuitability is not difficult:

• Condensate appears in the corners of the glass.
• A crust of ice is formed in a cold season on the windowsill.
• Traces of fungus or mold are visible.
• Cracks.
• Increased noise from the street.

Checking the density of closing the window

The thermal imager will be able to identify places of cold penetration, but there are simpler ways:

• Violation of tightness will determine the lit match or candle. Air penetration leads to fluctuations in fire.
• You can feel the draft with your hand.
• A piece of paper laid in a locked sash determine the density of closing the window. If the density is reliable, it will be difficult to pull the sheet back.

In favor of which element to compile the profile to make a choice

If you have purchased a finished profile from a little -known manufacturer, be sure that it uses the worst of the quality of the elastic thermoplast. It is convenient in the automatic assembly of the profile, quite cheap and safe (poorly burning). Therefore, in order to avoid such a trouble, try to control its use in your window or, after purchasing, immediately replace it yourself. To find out the type of sealing element that is used in the finished product will help a cut sample. It can be compared in the store.

Not only the color that is suitable for the window frame should affect the choice, but first of all the quality of the material of the element itself.

The choice will not be difficult if the double -glazed window from a well -known manufacturer who has already established itself in the market. But when choosing a profile of a less known company, it is necessary to focus on the specifics of some elements of the window.

Many companies copy the technology for the manufacture of windows for rating manufacturers, so most of the components of the profile are interchangeable. Nowadays, with the advent of online stores, the search for goods has much simplified. The choice of components is also presented on the Internet, the main thing is to know the size of the structure and add 15 - 20% to them for the reserve. Do not forget about the thickness of the layer, which should be identical to the previous one. Try to purchase a high -quality seal, saving money will be displayed on the functions of the double -glazed window. It would not hurt to study before buying the requirements of GOST 30778-2001. This will help make the right choice.

So that the seal lasts longer from time to time requires preventive care:

• Wipe and wash the windows and seal at least twice a year.
• Apply softening agents to the rubber product - glycerin or silicone solution so that cracks do not appear.
• Detergents with fat composition are contraindicated. He penetrates the structure of the seal.
• If the room is repaired and a lot of dust is carried out - close the window to avoid settling it on sealing elements.

Replacing rubber seals in plastic windows is needed when the methods to correct the malfunctions do not give results.

From the beginning, you need to try to adjust the density of closing the window. To do this, the key is inserted into a special opening and the turn is made until the desired result appears. If by adjustment the seal did not return to normal, it is time to change the seal. When it is not yet very worn out, you can resume it with aerosol lubricants.

DIY Plastic windows replacement

Tools and materials that will be needed:

• Pistol for glue.
• The glue is silicone.
• Scissors.
• New seal.

How to prepare for a replacement:

To carry out the procedure, it was more convenient - remove the sash. With a locked window, protective covers from the loops are removed. Pins are knocked out from the upper canopy. Holding the sash with an open window, it is disconnected from the frame. It is very important and it is necessary to know that the replacement should be carried out along the entire length only with a whole sealing ribbon. You can’t do this from pieces. It is also forbidden to stretch it. Free styling without stretching is recommended.

So, the described rules of this procedure described below will help to make everything qualitatively:

1. The old seal must be removed from the channels with scissors. To do this, you need to put it and pull it.

2. Be sure to wipe the released channels. Make sure that the pile does not get into the openings, it will interfere with the fixation of the new seal.

3. Glue should only be applied to the corners of the channels. Use cyanoplast or superglue 88.

4. After that, lay the new tape neatly and around the entire perimeter. Make sure she sat well in place.

5. Remove the extra parts with scissors.

6. Glue the joints to the corner of the frame.

7. Wait when the glue dries and insert the window frame into place.

Types of self -adhesive seals change in this way:

1. Put the window sash on the even surface.

2. Remove the protective tape from the seal.

3. Install a protrusion for fastening the grooves, which passes around the perimeter.

4. Press the tape, but not much.

5. Return the sash in place.

As you can see, the replacement of the seal of plastic windows does not require help from any of the specialists and almost everyone can cope with it.

Do I need to lubricate the seal?

If you want the compaction tape to serve longer, then you need to lubricate. Since rubber over time becomes dry and cracks appear. Special lubricants moisturize the material of the element and protect from the effects of the wind in the same way as the cream protects the skin of the face. Choosing a product should be carefully so that it does not contain dissolving acids. Such chemicals destructively affect the structure of the material and reduce the life.

Among the lubricants, ordinary petroleum jelly, glycerin are successful. Sometimes they advise for lubrication WD-40. Yes, it is needed, but to get rid of rust, not lubrication.

Previously, the properties of the seals and their types were superficially described. Let's analyze in more detail what type is the highest quality and effective in use.

For modern window structures, three types of material for manufacture are mainly used: silicone, rubber and polymer. Which of them has the properties that allow it to be less often replaced.

High quality PVC is used for polymer, but still this criterion does not give it the desired degree of protection from high and low temperatures. In the heat, he can soften, and harden in the cold. Ultraviolet rays also affect it negatively. About the use of polyethylene - you should not even think. It has the lowest quality of all. The most expensive - silicone, has disadvantages the same as polymer and inferior to rubber.

Universal and most common seal - rubber or rubber. It is more resistant to wear, has all the properties to protect against wind, temperature difference, sunlight.

Do not think that the color has nothing to do with quality. This is not at all like that, since elements that affect the characteristics of the product are added to the purchase of one or another color in the raw materials. For example, soot is added for black. It gives the material elasticity. Gray or white requires the addition of polymers, the properties of which are listed above. Consequently, colored sealing ribbons in quality are inferior to black, to that, over time, they darken.

So, as a result of comparing the properties of each type of material for the manufacture of the sealing product, the choice becomes clear. This is a rubber or rubber seal.

Window regulation for seasonal indicators is important for extension of operation. In the warm season, the eccentric at the end of the window is turned in marker inward, in the cold - in the opposite direction. In this way, you can adjust the degree of pressing of the wings.

Before you do some manipulations for caring for any technique and designs, you should find information about how this is done. Moreover, it is full of such on the Internet. You can even get an online consultation, because almost every manufacturer has its own site, which describes in detail the product and care for it. Not every consultant in the store will tell you in detail how to replace the seal, and on the network you will find what interests you. For comparison of the information, visit several sites and select the best option for you to select a window profile and replace the components.

Listening to all the recommendations for the care of window structures and their components you can provide energy conservation in your apartment and comfortably rest after a hard day.
