Gewölbte Lichtbänder aus GRILLODUR®

GRILLODUR®- Arched Continuous Rooflights

For an optimum glare-free room lighting

The arched continuous rooflight made of GRILLODUR® is the result of a consistent further development of the originally flat element. The self-supporting, curved construction comprises an aluminium grid framework. Semi-transparent fibre glass sheets are attached to both sides of this utilising a special adhesive process.

Due to its low dead weight of approx. 10 kg/m2, this continuous rooflight is excellently suited for roof refurbishment projects to increase the thermal insulation value without additional structural load on the existing substructure. U Values for the glazing of up to 0.8 W/m2K can be achieved.

Single or double flaps can be easily integrated for utilisation as qualified smoke and heat exhaust systems. The continuous rooflight is simultaneously structurally protected against falling through and hail and thereby provides even greater safety for your flat roof.

Utilise the arched continuous rooflight made of GRILLODUR® comply with the highest requirements. Benefit additionally for protection against heat, sound, sun and fire combined with glare-free daylight, excellent mechanical values and high chemical resistance. The application is particularly recommended for use in industrial, administrative and municipal buildings.
