Machinery installation of plastic windows

Today I was the old windows in Russia at the white plastic has become very popular. The reason is, first of all significant advantages of PVC windows profile. With the growth market of plastic windows and increase the number of firms offering services installation of window designs. And often these services are not very good quality. Because of this elation from having plastic windows can poutihnut. The consequences of improper installation are fraught with the following events: accessories wedge, double-glazed window appears on the condensate in the joints of window frames and slopes cracks begin to appear. All existing currently in the market of PVC profiles are products of high technology. PVC is extremely resistant to weathering and sunlight. In mounting angles are also used only those materials that use high technology: steam insulating tape, sealing tape, polyurethane foam and other components. In the manufacture of plastic window materials can be used with a variety of physical characteristics, and this design will be installed in the wall of a building consisting entirely of other materials with their physical properties. That is why the nodes walls and connections window design special requirements. In general, they reduce to the fact that the site shall be so located on the thickness of the wall to prevent the emergence of the inner surface of the wing boxes, and the slope temperature below +9,3 ? C (at 50% RH ambient temperature +20 ? C), which corresponds to the "dew point" and leads to the formation of condensate. Implementation of this requirement is possible only when professionally executed calculations and recommendations of manufacturers. There are 3 ways to install windows of PVC profile across the thickness of the wall. 1) PVC window profile is mounted close enough to the outer surface of the wall. This option is used most often. The client receives a wide sill, and the appearance of the building is not broken. In reality, this option is one of the worst, if we start from the physics, because a very high probability of the isotherm the sash, box and slope. 2) Plastic box mounted close enough to the inner surface of the wall. This option is used infrequently. The client receives a narrow window sill, look of the building somewhat disturbed, because the window is recessed deep into the wall. 3) The most correct and acceptable way to install plastic windows - close enough to the middle of the wall. This method is most effective in terms of combating the condensation. Quality installation site directly affects the quality of the plastic window. That is why it is important, and design. When used in the assembly site, there are various physical processes. Due to the difference of thermal expansion coefficient materials doors, boxes, walls and windows are displaced components of PVC windows relative to each other during their cooling and heating. Quite often happens that the box is not rigidly connected with the wall (by unscrupulous workers save on the bracket, placing cheaper than recommended by the manufacturer), then compression and expansion boxes are transferred to the assembly foam. Polyurethane foam with such influences can easily begin to crumble and crack. Another reason for the destruction of foam can be confidently called the formation of condensation in the foam, which has the property to penetrate through the walls of buildings. This high-quality site, performed in compliance with all necessary technical requirements in the early assembly attached vapor barrier tape, and after the installation of PVC window profile with foam fill the joint between the wall and a box of tape fastened to the wall surface. To avoid mistakes when installing plastic windows address only to companies well-proven in this case. Quality installation will save you from wasting of the nerves, time and effort to reinstall the plastic windows.
