The attic windows are installed under the slope so that they pass 40% more light than in ordinary windows. Moreover, from the attic window you can get night lighting from the stars, due to the fact that it saves the resident of the house from light pollution of the medium (when street lamps spread multiple light, and not reflected).
Mansard windows set a special rhythm of volumetric space. The window tilt allows the use of the reflected light to create unique color-light compositions.
When installing an attic window, the level of lightness of the attic (the proportion of the ratio of glazing and floor 1:10) and the viewing sector from an open window with a seated person (at least 15%) is calculated.
Usually placed attic windows at a distance of 0, 9-0, 11m from the floor, so as not to cause the effect of closed space. For glazing, special glasses are used (they are not divided into fragments, but into small granules) or triplex (double glass with a special simple -piece).
Given that with an inclined installation there is an additional load on the window, high -quality attic windows will differ in increased strength and tightness.
