When this happens you will need to carry out the replacement of the seal, it is quite possible to do it yourself.

concept and purpose of the seal

Before you replace the gasket should understand what it is and where it is located in the glazing system.Thus, the sealing tourniquet is a rubber layer having a relief or a spongy structure, which is fixed between the special grooves in the windows.This harness passes around the perimeter of the window opening, and has the characteristics of resistance to bad weather conditions.

Due to this, the seal is not exposed to cold cracking or deforming under high temperature.But the main advantage - it does not pass the living space of the heat, humidity or cold, thus regulating the climate control in the room.

Types seal in modern windows

• rubber or rubber seal - the most widespread form of layers.It is characterized by low sensitivity to temperature changes, high resistance to mechanical damage and UV resistance.
• Seal Polymer - a popular type of material, which is made of modified PVC, iefrom raw material similar to plastic profile window.It securely and provides a high tightness of the window construction.But also it has a number of drawbacks: unaffected by temperature changes of the environment, ultraviolet light and can lose elasticity.
• seal plastic with foam filling - different forms of monotony and low recovery characteristics.

When you need to change the seal?

rubber seal - quite an important component of the window system, which is responsible for sealing the plastic glass.From its functionality depends on how well the window cope with providing sound insulation, temperature control and protect the room from getting unpleasant smells from the street.

2. penetration of cold or ambient noise in the room.
3. appearance of condensation on the windows.
4. emergence of ice in the winter on the windowsill or in a window.
5. Manifestations depressurization glass.

Important! undesirable to acquire a sealing layer of thickness greater than the one that was originally set.The popular notion that a thick sealant may have higher leakage performance, noise insulation and an increased service life, is wrong.On the contrary, such a seal is more susceptible to deformation, which greatly reduces its life.In addition, too thick layer - an additional load on the locking window fittings and hinges that in the future will affect not the best way to longevity windows.

Nor should we make the mistake of buying cheap and useless for plastic windows universal silicone sealant.Its use is justified only in case of sealing of wooden windows, made according to the old model.For PVC windows need to use a special material corresponding to GOST 30778-2001.
