Window blocks are most often installed by experts, although the installation of blocks purchased in accordance with the size of the openings is possible to save, with your own hands. For the proper installation of blocks, whether they are wooden or PVC, you must have a level and a plumb line. The absence of distortions in horizontal and vertical planes provides a reliable installation of a window unit.
Violations of the correct installation may not be identified immediately, so you need to know where to buy windows. In case of fluctuations in the ambient temperature in such window blocks, they can even crack due to uneven thermal expansion or compression.
Having installed the box, the window sash is hung on it, after which the quality of their opening and closing is checked. Only after that is the entire window block fixed in the opening. This is done using nails or special iron ruffs. Wooden traffic jams should be installed in the brick walls, into which this fastener is securely clogged. The gaps left between the unit and the walls of the room in the window opening, after the final installation of the unit, are covered. Excess foam after hardening is cut off and the window is decorated with slopes, the windowsill so that the layer of foam is not visible.
