Current technology of joinery is high. Buying energy-saving windows is half the battle. The second half of the success is a properly executed installation of such a window. Unfortunately, the lack of skills construction staff in the proper installation of windows can cause damage to or loss of all the windows are so important for our values ​​of energy-efficient windows.

Here are some common errors that fitters make:

• Install windows with only foam, and give up the anchor
• If They use anchors or dowels that are improperly used – mounted
• Insert window in either too small or too large apertures in the wall
• Bad sealing the gap between the window and the wall

Water vapor escapes into the gap mounting between the window and the wall, which is usually filled with foam mounting. In winter by cold water condenses and wets the foam, and the foam at a low temperature forms a heat bridge, which destroys energy efficiency of the window. An example of such incorrect installation of the windows are damp jamb on which grow fungi and molds that we breathe every day.
