Save time with our System Solution
For each GLASSFLOOR we offer a custom-made insulating frame (30-250mm). Together they provide the perfect system solution for thermal insulation and external sealing. The insulating frame can also be made for slopes on request. The combination of insulating frame and GLASSFLOOR allows quick installation and efficient external waterproofing for all types of flat roof waterproofing.

All this is GLASSFLOOR
Affordable & immediately available
We offer custom-made and standard products at attractive prices. Standard sizes are available immediately from stock.
Best Quality
We only use high-quality materials: extra-clear glass for maximum light transmission values and a colour-neutral, clear view. The outer and inner frames are made of stainless chrome steel for maximum dimensional stability and resistance to natural, external influences.
Timeless Design
The minimal and timeless design of GLASSFLOOR blends seamlessly into its surroundings. The walk-in glass sets architectural accents for a new sense of space and well-being thanks to more natural daylight.
Quick & Easy to install
GLASSFLOOR offers architects, planners and roofers the perfect ready-made solution for thermal insulation and external sealing. Our skylights are supplied as a complete solution - and only need to be foamed and screwed into place. Prefabricated metal lugs and holes on the outer frame facilitate placement with a construction crane and screwing into the support.
System solution with matching insulation frame
We supply the matching insulation frame on request for an even more efficient installation and sealing process. The insulation frames are very robust thanks to a fully bonded pressure distribution frame and can also be manufactured as a height compensation or slope element on request.
