Therefore, only highly qualified professionals should install it, and upon completion of this work, a long-term quality guarantee must be issued!

At installation work They use special construction foam that quickly hardens. After it dries special attention care must be taken to ensure that there are no gaps left in the areas where it is used.

An important point that many people don’t pay attention to! At the stage of processing the foam and its drying, the doors to the room in which work is being done on the window opening should not be opened, or they must be removed, or at least slightly opened, window sashes. Why is this necessary?

The point is that when closed windows, opening the door can create a certain vacuum, which will be quite enough to break the tightness of the foam that has not yet hardened! Even completely unnoticeable holes may form in it, which, however, will be enough to feel the blowing and draft from the window in the cold season.

The order of installation of slopes and window sills.

Finishing the slopes is the first place to start work. First of all, they install the upper slope, which they then focus on. A lower slope is installed parallel to the upper one. The side slopes are adjusted between the upper and lower ones. The sequence of left and right is not so important.


Installing a window sill is a special stage that, in addition to the main algorithm, has its own nuances!

1. Fix it clearly and firmly.

2. There should be no deflections along the entire length.

3. It should be set at 90° in relation to the position of the window (+- 2-3 mm is the maximum permissible deviation).

4. The width of the slopes should not exceed the width of the window sill!


“Ears” are cut out along the edges of the window sill. They provide a finished look to the entire structure. At the ends, on open parts, they are installed decorative corners. At the bottom of the window sill everything is treated with foam and putty. Sealant or silicone is used to seal the seams that separate the sill from the slopes.

There are plastered slopes, and there are also overhead slopes. Plastic slopes belong to the second option. Invoices are most often made from plastic plates, or from wood veneer. It can be noted that, in fact, the slopes, their finishing, is the final touch in not an easy task installation of plastic windows.

Finishing of slopes is required both when installing a new window in a newly built house, and when replacing a window with a new one (especially if old ones are replaced wooden windows on modern ones - plastic).


Slopes, which are installed using the plastering method, are already becoming a thing of the past for a number of obvious reasons. They are being replaced by modern, high-quality plastic slopes. They are very quickly installed, provide additional thermal insulation, do not require maintenance, do not crack or fade. Plastic slopes are made of polyvinyl chloride. This is an environmentally friendly material!

There are 2 types of PVC slopes:

Panelite is a hollow plastic panel, which is equipped with ribs inside that give it rigidity;

Sandwich panel - foam insulation covered on each side with plastic. External side The panels have a melamine coating that protects it from chemical and mechanical stress. Sandwich panels are easy to clean, can be used for decades and guarantee a high degree of sealing at the joints.
