Flat roof windows - Flat

Eye-catching flat glass solution

While the classic VELUX flat roof window comes with a dome, the flat roof plane glass model introduces a beautifully integrated 4 mm hardened glass pane. 

Inside, the newcomer matches all specifications of a classic VELUX flat roof window. Outside, the plane glass stands out as a stylish and minimalistic design feature with underlying black bordering and discrete profiling.


With a fixed (non opening) flat roof window, you can transform and improve any space. VELUX flat roof windows CFP add the daylight you are looking for to rooms with very little natural light.


The double glazed unit has a laminated inner pane for additional safety. Externally the plane glass design with underlying black bordering makes the window stand out as a very stylish feature compared to older flat roof domes.

Available in eight sizes.
