Glass Roof
Keep rain, snow and cold out and let the light in. Add guillotine glass, sliding glass or zip screens underneath to turn the terrace into a room.

Overview
A glass roof is a roof system of fixed glass panels on an aluminium frame. INORMA LUMEN GLS R-300 is made watertight with clip-in gaskets, and its filtered gutter outlet prevents clogging and leaks.
It projects up to 4 m. Above 4 m width an intermediate post is added, and panes are planned at roughly 1 m wide. LED lighting can be added for evenings.
LUMEN works as a terrace cover on its own, but it shines in combination: add VISTA guillotine or THERMA sliding glass on the sides and a SKYLINE ceiling zip blind underneath, and you have a fully equipped winter garden.
