After plastic windows are installed, slopes should be made that will give an aesthetic and finished look to the room. You can finish slopes with plastic yourself.
Wooden rails are attached along the perimeter of slopes with self -tapping screws. Make sure that the rake goes flush towards the wall, does not play behind the edges. Wooden rails must be leveled using the level. Then the starting strip is attached along the outer edge of the window. For attaching P-shaped plastic, use clips self-tapping screws are used. However, before fixing plastic, it is necessary to outline the upper horizontal, left and right vertical using a level and a pencil. A strip of the plastic panel will be put into the groove in the starting strip in the starting strip.
Measure the required height and cut the F-shaped molding. Attach a cut panel to the outer side of the slope (you can fix the panel to a wooden rail using a furniture stapler).
A slope is cut out of plastic panels. Measure plastic enough accurately accurately. One side of the panel is inserted into the P-shaped molding, the opposite side of the panel is inserted into a F-shaped molding. Thus make all three slopes. To warm the slopes under the panels, lay a layer of mineral wool. In the corners of the opening, the joints are sealed with white silicone. The joints can also be recorded with a special profile.
