How to replace the window seal with your own hands

The glass windows and PVC windows today are almost in every home, and if they are installed, taking into account all the rules, then a person is securely protected from cold, excess noise and wind. However, in some cases, even the most high-quality plastic windows lose their properties, and drafts, dust, moisture, etc. begin to enter the space, and so on. In case of such a situation, it will be necessary to replace the sealer, which can be made independently.

Concept and appointment of the seal

Before replacing the seal, you should figure out what it is and where it is located in the glass package system. So, the sealing harness is a rubber layer having a relief or spongy structure that is fixed between special recesses in the windows. This harness passes around the perimeter of the entire window opening and has the characteristics of stability to poor weather conditions.

Due to this, the seal is not susceptible to cracking in frost or deformation under the action of high temperature. But the main advantage - he does not let the heat, moisture or cold in the residential space, thereby regulating climate control in the room.

Types of seal in modern windows

• Rubber or rubber seal - the most widespread type of layer. It is characterized by a low level of sensitivity to temperature changes, high resistance to mechanical damage and resistance to ultraviolet rays.
• The polymer seal is a popular type of material that is manufactured from the modified PVC, i.e. From raw materials similar to the plastic window profile. It is reliably fixed and provides high tightness of the window structure. But also has a number of shortcomings: subject to the effect of the temperature differences of the external environment, ultraviolet and may lose elasticity.
• The polyethylene compactor with foam filling is characterized by monotony of forms and low recovery characteristics.

When is it necessary to change the seal?

The rubber seal is a fairly important component of the window system, which is responsible for the tightness of the plastic glass. It depends on how well the window will cope with the provision of noise insulation, maintaining the temperature regime and protect the room from incoming unpleasant odors from the street.

However, there are some signals that will help the owner to determine when it is necessary to replace the seal on plastic windows. These indicators include the following phenomena:

1. The emergence of drafts.
2. Penetration of cold or extraneous noise into the room.
3. Appearance on condensate windows.
4. The emergence in the winter time is nondes on the windowsill or inside the window.
5. Manifestations of depressurization of the glass package.
6. The occurrence of dryness and cracking of rubber.
7. The appearance of fungus and moldy formations on the rubber product.

The emergence of such signs will clearly indicate that the rubber seal does not cope with the functions allocated to it. In other words, it is necessary to lay a new high-quality sealing cord.

Selection of sealing layers

If the profile of the plastic window structure is made by the famous brand brand, then pick up and buy a seal of consulting design or type will not be difficult. But regarding the profile system of third-party brands, when choosing a rubber harness, it is necessary to take into account some features.

Almost all the profile systems from little-known manufacturers are clones of brands Veka, Rehau or Kbe, and, accordingly, the interlayer will be interchangeable. Thus, the KBE manufacturer's counterparts are profile systems such stamps as: vitrage, Novotex or Proplex. While Rehau's seal will become an excellent substitute for Montblanc or BrusBox windows.

It is also important not to borrow that the window sealing harness can be purchased solely by the whole bay of several hundred meters. Modern web stores and large constructionarkets sell this product, both wholesale and retail. This allows you to buy the required cross meters of the seal without difficulty, you only need to accurately measure the parameters of the window design and take the material a bit with a margin.

Important! It is undesirable to acquire a sealing layer in thickness exceeding the one that was initially delivered. The popular view is that a thick seal can have higher tightness, noise insulation and an enlarged service life, erroneously. On the contrary, such a seal is more prone to deformation, which significantly reduces its service life. In addition, there is an excessive thick layer - an additional load on the locking window accessories and the loop, which will later affect the continuousness of the window durability.

It is also not necessary to make a mistake, purchasing a cheap and useless silicone universal seal for plastic windows. Its use is justified only in the case of sealing of wooden windows made by the old pattern. For PVC windows, it is necessary to use a specialized material that corresponds to GOST 30778-2001.

How to extend the service life of the seal?

It is always better to prevent the problem, rather than solving it difficult and costly. Therefore, it is much easier to avoid the rapid wear of the sealer for windows by conducting light preventive measures. Among such precautions and care should be selected as follows:

1. No less than 2 times a year, it is necessary to thoroughly wash and wipe the windows not only from the inside, but also outside the room, since the fallout of garbage and dirt will noticeably harm the operation of the seal.
2. It is possible to periodically apply on a cleaned sealing layer of a special solution in the form of a silicone-containing drug or ordinary glycerin, which can be purchased at the pharmacy.
3. When washing window structures it is desirable to avoid using fatty detergents to avoid their falling inside the seal and spider harness.
4. Perform repair work or other dusting procedures in the room are necessary when the window is closed, so that the dirt and dust is not settled on the seal. Otherwise, clear the contaminated harness will be problematic.

Replacing the sealing cord with their own hands

If the sealing layer has become unusable, and requires urgent substitution due to the loss of high-quality and functional characteristics, the following aids should be prepared:

1. Silicone glue.
2. Pistol for glue.
3. New seal.
4. Scissors.

Further replacing the sealing . In order to avoid any difficulty or possible errors when installing a new layer of a sealing harness, it is worth adhere to such instructions:

1. With the help of scissors, push the edge of an old sealing harness and remove it from the window opening. Usually it is easily removed from the window frame grooves.
2. The released place in the profile is thoroughly cleaned from pollution and dust by means of soft clean fabric. It must be done not for the purpose of aesthetic comfort, and in order for the new harness more densely to the purified grooves.
3. Apply glue to window frame angles to fix a new cord.
4. Sealing harness gently start in the grooves. It should be walking throughout the window perimeter area.
5. Putting the seal in the corners of the window frame, without its tension or pressing, follow uniformity.
6. Excess rubber tail cut off with scissors.
7. The single joint of the sealing is secured by glue in the corner of the window frame.

Important! When laying a new sealing cord in a window perimeter, you should take a one-piece cut. In no case to break and not cut it, not to lay parts.

When gluing a rubber sealing layer, it is necessary to place it in the groove of the frame uniformly, freely and covering the surface of the grooves.
