How to avoid 10 typical problems with installing double-glazed windows

During repair or just when replacing windows, many people have a question, how not to make mistakes when installing double-glazed windows? If the installation is carried out incorrectly and poorly, then the heat will not be retained for a long time in the room, the cold will enter the apartment, which in the end can even destroy the window frames. What to do to avoid popular problems with installing windows.

The window size was incorrectly determined

This oversight occurs due to incorrect measurement of the window opening, and it cannot be installed there at all. If it is very large, then the insulation layer does not fit in any way, and if it is very small, it will look just awful. In any of these cases, the normal installation of a double-glazed window will be simply impossible. Over time, it will be possible to wait for purging and the appearance of moisture. Therefore, it is necessary to correctly determine the window size so that such problems do not arise.

The surface was not cleaned properly.

To avoid such a typical problem, it is imperative to remove any debris, dust, mortar, and remnants of the previous seal before installing windows (if replacing old windows with new ones).

Incorrect installation of windows, thermal insulation of walls not taken into account

If the wall is single-layered, then be sure to place a window in the middle of it. If the wall is three-layer, then the window must be placed on the plane of thermal insulation, and in the two-layer - on the very edge, next to the insulation, or even go beyond it.

Poor window deposition in the wall

You should not close the window to the slope or platband, because you can not make a quality seal there. The correct distance is 1.5 centimeters.

Drain hole clogged in plastic windows

Plastic windows will lose their tightness over time, and the frame will eventually deteriorate. Ideally, it is worth using the system of additional profiles, and select the windows to the platband that already exists.

No window sill trim

But it must be, and most importantly, that the frames are a bit narrow, so that you can easily install an external window sill under it.

The plastic window is not well attached to the wall

It is important when installing windows to use a large number of dowels or anchors so that the frame does not deform over time and the plaster around the windows does not crack.

Support wedges not installed or installed, but not where necessary.

You can not install the window frame directly on the wall or insulation layer, otherwise moisture and cold will be passed.

Joints poorly filled with foam

The main thing for filling the cracks is to use only mounting foam and do it very carefully.

Not used vapor barrier tape

Be sure to use a vapor barrier tape, not only on the inside, but also on the outside of the vapor-permeable tape.

If you do not make these mistakes, then the windows will last a long time and will not cause problems during operation.
