Installation of a plastic window, ends on the processing of slopes. Slopes are external and internal, and are on the surface of the window opening. The outer sides of the seams between the window blocks and the walls are sealed, the mounting foam should not take moisture and rays of the sun. Often, when dismantling the old window, internal and external slopes tend to partially collapse, which is why, to support aesthetics, a cosmetic decoration of the external slope is made.
