The process of installing plastic windows does not end with the installation of a double-glazed window, but requires finishing the slopes. For the interior of the window openings, materials such as plasterboard, plaster, plastic, wood, tile or stone are suitable. For outdoor slopes it is recommended to use materials resistant to external influences( temperature drops, moisture, wind), metal, plastic, clinker brick is the best choice. The most common decoration slopes with plastic, plaster and drywall. By the way, now there is an innovative way of plastering the ceiling by installing a large pressure. In turn, it turns out more advantageous stretch ceilings.
Slopes with your own hands
Finishing slopes with plaster yourself
This method of finishing has been used since a long time, it attracts with its simplicity and cheapness, however it will take more time than other methods.
Before starting work, it is necessary to prepare the surface: clean it of dirt and dust, close the frame and window sill with a film to prevent contamination, fill in existing cracks, fill the gaps between the wall and the frame with mounting foam, cut excess foam after stiffening with a knife.
The surface is leveled during the work. To do this, use beacons that are 3-5 cm from the window frame, and a wooden bar as a guide. Then they begin to fill the grout with mortar along the perimeter of the glass unit. Then trim the slope from bottom to top with a thickness of not more than 6-7 mm.
You can paint slopes immediately after it dries.
Plastic slopes
For finishing the slopes with plastic, it takes a little time and skill, and the result will be pleased with the finished neat appearance. Such a slope does not need to be additionally plastered or painted.
For the device of slopes from PVC it is necessary to make measurements and to cut out an available material on strips. Then, along the perimeter of the window, a U-shaped profile is fixed with screws. On the outer part of the window opening flush to the wall is installed a wooden rack, on which the brackets are fixed with an F-shaped profile. Then proceed to the device slope. Plastic billets are installed in the formed grooves.
The area between the wall and PVC sheets is filled with mineral wool insulation and mounting foam. Joints between the wall and the slope are closed with a plastic corner around the perimeter. Joints between plastic sheets are filled with a silicone sealant of suitable color.
Finishing of plasterboard slopes
Finishing of slopes of gypsum plasterboard - the most labor-consuming method of the listed. Preliminary it is necessary to make measurements and perform the cutting of the material. Drywall should be taken moisture-resistant( GKLV) to prevent dampening of the material and the formation of mold and fungus. 
The cavities formed are filled with a mineral wool insulation or mounting foam. After the work is finished and the foam is dried, it is cut with a knife, the excess of plasterboard is cut off, joints and seams are plastered. Then finish coat of putty and paint is applied.
Finishing slopes by any of the above methods - an occupation though laborious, but on the shoulder of an ordinary person. The main thing is not to postpone the execution of these works, since the unfinished slopes lead to a deterioration of the thermal insulation properties of the windows, due to deformation and damage to the mounting foam.
