Greetings, dear guests!

Windows and doors are those elements that, upon completion of construction, give the house the appearance of completeness, and often become the main decoration of the facade. One of the main design features of windows is the presence of window quarters.

The window or door quarter is the protrusion of the facing material in the opening behind the rough material from which the wall is made. For the most part, a quarter is done in stone houses, since only in them there is an opportunity to make a ledge, unlike, for example, houses from a bar.

A quarter is done in the upper part of the opening and on the sides, the lower part remains in the same level without drops. The quarter performs not only an aesthetic function, but also serves as structural elements, to which a sealing tape is attached during the installation of the window frame in order to minimize the blow-through.

In the window openings of houses where quarters cannot be made due to the peculiarities of the used construction materials, the resulting gap between the frame and the wall is closed with special cover strips or plastered.

After talking with window installers, I learned a lot about quarters and in this article I will clarify everything ...

With a very large depth of a quarter, the masters, in the process of foaming the joints with polyurethane foam, cannot make the correct seam, in such cases it is necessary to pass along the perimeter of the window twice, and accordingly - with a double overrun foam. With a small quarter depth, we risk getting a weak seam.

The very concept of "quarter" means a quarter of the length of a standard brick, which is 25 cm, so a quarter of the length of a brick is 6.25 cm. And self-builders often have a question, Is six centimeters enough for the installers to properly install windows?

According to the rules for installing metal-plastic windows, the frame should be overlapped with facing material by 2-3 cm, and the distance from the main wall to the end of the window frame should be 3-4 cm, this is the gap that is needed for a high-quality assembly seam - the foam has room for expansion, and accordingly there will be no unnecessary ones in the frame stress.

Secondly, a gap of 3-4 cm is the optimal distance for installing a sandwich panel slope. The panel goes under the frame and eats up 1 cm, leaving 3 cm for the seam.

Thirdly, in order to let more light into the room, the slope in relation to the wall should have an angle of more than 90 degrees. This is called the "dawn" of the slopes:

Dawn also graces the window aesthetically.

Therefore, the optimum window quarter depth should be 6 cm with a tolerance of 5 mm.

And that's all, I hope the article was useful to you!
