Window Installation Height
In buildings where storeys are below 25m above ground level, the distance from the bottom edge of the opening window to the floor should be at least 0.85m. In buildings where storeys are more than 25m above ground level the aforementioned distance should be not less than 1.1m. It should be noted that the higher the window is fitted, the more light enters the room, therefore FAKRO roof windows are equipped with a bottom handle opening system to facilitate the opening of the windows installed at optimum height. The bottom edge of the FAKRO roof window should ideally be situated 1.1-1.4m above the floor level. The recommended distance is 1.2m (bearing in mind that average room height is 2.5m), which provides a lot of light into the room and simultaneously offers an unrestricted view.
Installation of the window at this height allows the fixing of a standard radiator below the window and also allows proper lining construction. Thanks to this proper air circulation along the window glazing reduces the risk of condensation appearing on the window.
The Window Placement
When deciding how and where to place roof windows we should consider an option to use a number of smaller windows placed in different parts of the roof rather than one larger as, thus much better illumination of the room is achieved.
The Right Windows
The choice of roof windows depends on:
