Attic windows

To successfully place the window, the top of the window opening should be at least two meters from the floor. Solar attic lighting should ideally flow throughout the floor. The attic windows pass only the right amount of light with a smaller area of ​​the opening. It was proved that the ratio of the area of ​​attic windows to the floor area is 1 to 10. This means that a person will be quite enough on ten square meters of floor area, one square meter of window area.
