Roof Windows

Roof windows differ from common windows in that these types of windows are installed on the roof and designed to let in natural light into your rooms. This method of naturally lighting rooms has become quite popular as manufacturers adopt new technology and approach to make windows ideal for lighting and resistant to UV light.

Here at MGN Builders Merchants, we offer pitched roof windows from reputable manufactures such as VELUX. For more information concerning our VELUX roof windows, give our customer service team a call via 01708 985 022.

What Are Roof Windows?


A roof window is a window style that opens outwards and it is integrated as part of a roof’s design.

Roof windows are intended to let in more natural light and fresh air into your rooms. Besides, they also allow you an unhindered view of the sky.

Often, a roof window is fixed into the original structure during construction, though it can be fixed into existing structures depending on the building regulations of a particular region.
