Methods for installing plastic windows
In the process of installing plastic windows, there are three ways to attach the window frame to the wall. Fasteners with the help of anchor dowels, fixation with construction screws and installation using anchor plates. In the first installation method, the window frame is set in terms of vertically evenly. Then, in the side ribs of the frame, through holes are drilled from the inside. Their depth is usually 10 – 12 cm and is calculated so that the anchor dowel completely passes through the frame and drown in the wall. Then the anchor dowels are tightened with a screwdriver, and the opening between the frame and the wall is filled with mounting foam. In the second method, when the fasteners are performed using construction screws or what they are also called frame screws, the principle of fixation is almost the same as in the first method. The through holes are drilled through the frame, plastic dowels are inserted into them and construction screws are twisted in them. After that, all voids around the perimeter are filled with mounting foam. These two methods are simple and fix the window frame tightly, but there are significant disadvantages. In places of sparkling into the window frame, tightness is disturbed, a peculiar “cold bridge” is formed in winter, condensation appears and metal corrosion occurs. A way where anchor plates are used to attach a window frame to the wall, the most promising. The fasteners of the window frame on the anchor plates are quite simple. First, with the help of self -tapping screws, the plate is attached to the window frame. When 2 – 3 anchor plate on each side of the frame, the frame is inserted into the opening and with the help of dowels of nails, the anchor plates are fixed to the wall. The advantage of this installation method is that the tightness of the window itself is not violated, which is very important in the cold season. Also in the hot season, plastic windows are able to “play”, slightly change their shape, the anchor plate prevents possible distortions.
