Our round, walk-on skylight
CIRCULAR WALK-ON – light design using daylight
As a walk-on glass surface and beautifully shaped design object, the CIRCULAR WALK-ON skylight forms the ideal basis for a well thought-out room and lighting concept.
The skills of our round, walk-on skylight
With a load-bearing capacity of 500 kg/m², the flat roof window is an extremely robust, thermally insulating and ecologically sustainable skylight. All of its components are up to 99 % recyclable. It is available in sizes from 600 to 2000 mm in diameter. The insulated substructure can be adjusted in height by up to 750 mm.
With its excellent thermal insulation properties, it makes a significant contribution to energy efficiency in both new and existing buildings. The triple-glazing is suitable for passive houses, the uninsulated version is sufficient for interior use. An anti-slip coating allows you to walk safely over the glass.
SkyVision CIRCULAR skylights are also available as a non-walk-on version.
We also offer a non-walk-on version of the SkyVision CIRCULAR skylight for anyone who would prefer to do without this feature.
