Tech installation of window designs

Change the old Soviet-style windows, new white plastic now has become very popular. There are several significant advantages of PVC windows. But with the growth market of plastic windows, and increased the number of firms responsible for the installation of window designs. And not infrequently services, which provide these firms are nekachestvennymi. Because of this joy of having new windows could darken: at the junction of slopes and window boxes appear cracks in the glass-packet falls condensate and accessories shim. The vast majority of cases - that the consequences of improper installation.

All current window profiles - a product of high technology. PVC stands to solar radiation and atmospheric effects. In assembling the corners, ie, in connection with a wall of translucent structures, also used materials based on high technologies in the construction chemicals: mounting foam , Pre-compressed sealing tape, paraizolyatsionnye belts and other components.

Plastic window can be made of materials with different physical characteristics, and this construction is installed in the wall of the building, which is most often made from different materials with their own physical properties. Therefore, the sites compounds the window and wall constructions subject to special requirements based on the laws of physics building. In short, they are that site should be well designed and well located on the thickness of the wall to avoid the appearance of the inner surface slope, boxes and leaf temperatures below 9, 3 C ( at room temperature 20 C and humidity of 50%), Which is a "dew point" and is causing condensation. This can be achieved by implementing the recommendations of manufacturers and professionally executed calculations.

There are three options for installing plastic windows on the thickness of the wall.

1. Plastic box mounted near the outer surface of the cold part of the wall. This option is used quite often. The face of the building is not violated, and the customer receives a wide windowsill. In fact, this is the worst option in terms of physics, because very high probability of exit isotherms to dip, box and stvorku.

2. PVC window located close to the inner surface of the wall - he rarely used. In this case the sill is a narrow, outside the window looks neestetichno, because recessed inside wall, while the broader external vodootlivnom sheet will be snow in the winter .

3. The most reasonable and correct way of installing plastic windows in the brick house - near the middle of the wall. This method is most effective in combat positions condensate.

Without quality assembly site has no quality windows from PVC. It is therefore important that its construction. In the operation in the mounting site pass certain physical processes. By the difference of thermal expansion coefficient of the wall, boxes, leaf and glass units occur reciprocal movement of the plastic window on one another in their heating / cooling.

It happens that the box is not enough tightly connected with the wall (neglectful workers save expensive fasteners and place them less frequently than recommended), then the expansion / contraction of the box handed to the widely used mounting foam. Pena, with high rigidity ( and fragility - with significant negative temperatures), may start crack and crumble.

The second reason for the destruction of foam is a condensation of water vapor, which is in a warm room and has the property to penetrate through the walls of the building exterior.

In qualitative site carried out in accordance with all requirements, at the beginning of mounting sticks Vapor tape, and after the installation of plastic windows, through mechanical and casting foam interface between the mounting box and the wall, the ribbon affixed to the wall surface. In the lower site, outside the mounting profile and the surface of window aperture can be glued vlagozaschitnaya tape, which protects the wall from falling rain water.

To avoid mistakes when installing windows installation of PVC go only to specialists.
Qualitative assembly will relieve you of additional concerns and the costs of expensive pleasure in the form of reinstall Windows from PVC.
