From which material is the outer cover of skylights made?

Protection from rain, snow and other weather conditions

The roof window’s outer cover – also flashing frame – creates a transition between the roof and the roof window frame. The skylight is protected from the weather. Standard external covers are usually made of aluminium sheets in the corresponding standard colours of the manufacturer. Aluminium is light, inexpensive, weather-resistant and easy to clean and can be supplied in many RAL or NCS colours on request.

If copper or zinc has already been used in the roof design, the exterior covering can optionally also be made of copper sheet or titanium zinc – but at higher prices.
