But this is neither a truly flat roof nor a typical pitched roof.
The roof of this day-care centre in Immenstaad on Lake Constance is partly flat and partly sloping at up to 30°.
The primary advantage of the SkyVision skylights is the angle of the roof
SkyVision CIRCULAR roof glazing is suitable for roof pitches from 0 to 30°, which is well above the usual maximum pitches of 15° for skylights and skylight domes.
The second advantage is the thermal insulation!
The triple-glazed GLASOLUX SkyVision windows have a Uw value of 0.87 W/m²K, which is absolutely top class. The lower this value, the less energy, i.e. heat, a window emits. For comparison: simple skylight domes have a Uw value of approx. 2.5 = W/m²K.
