QR code video tutorials on each GLASSFLOOR

We send each GLASSFLOOR with a QR code showing our video tutorials, so we can support our customers on site for an efficient installation.

Save time with our System Solution

We offer a customized insulation frame (30-250 mm) for every walkable skylight. Together they form the ideal system solution for thermal insulation and external sealing. On request, the insulation frame can also be made for specific slopes. The combination of insulation frame and GLASSFLOOR a quick installation is possible, which effectively seals the flat roof window.

We produce our walk-in floodlights in compliance with the applicable DIN standards:

DIN EN 1991-1-1
DIN 18008-5:2013-7

A duo that complements each other perfectly.

All this is GLASSFLOOR

Affordable & immediately available

We offer customized solutions and standard products at affordable prices. Standard sizes are in stock and available immediately.

Best Quality

In the manufacture of our skylights, we rely exclusively on first-class materials: extra-clear glass with the best possible light transmission values and a color-neutral, clear view. The outer and inner frames are made of stainless chrome steel, which ensures maximum dimensional stability and resistance to natural external influences.

Timeless Design

The simple and timeless design of the walk-in skylight GLASSFLOOR skylights blends seamlessly into its surroundings. The walkable glass surfaces add architectural highlights that create a sense of space and additional well-being through more natural daylight.

Quick & Easy to install

GLASSFLOOR offers architects, planners and roofers an ideal complete solution for thermal insulation and exterior waterproofing. Our walkable skylights are supplied as a complete set that only requires foaming and screwing. Prefabricated metal lugs and pre-drilled holes on the outer frame facilitate positioning by means of a construction crane and fastening to the support.

System solution with matching insulation frame

On request, we also offer the matching insulation frame at the same time to make installation and sealing even more efficient. The insulation frames are characterized by their robustness, thanks to a fully bonded pressure distribution frame. In addition, they can be made on request as a height compensation or slope element.
