How to install PVC windows in a wooden house

You may need to replace any parts of the opening. For example, in chopped houses, the areas of logs located under the window opening most often suffer. In this case, the damaged areas are cut out and replaced with pieces of logs of suitable size. Replaced areas are fixed, depending on the possibilities – with staples, long trimmers, wooden locks (groove-tenon).

Be sure to treat the replaced area with protective compounds.

Installation of windows in a window box (for chopped wooden houses, installation of a window box is carried out using a mowing or casing) is the most appropriate way to install windows. Thus, the rigidity of the aperture is preserved, a strong base frame is created. But at the same time, the window itself will be able to self-regulate during seasonal fluctuations of the house (shrinkage, movements, etc.).

When installing the window box set on the level.

On each side, be sure to leave a gap of at least 1 cm, set the bars between the frame and the window box. They will not allow the frame to move horizontally, prevent a possible deformation of the frame during installation and allow you to securely fasten the window frame to the window box.
