GRILLODUR®- Saddle and shed continuous rooflights

Continuous rooflights for special requirements

The GRILLODUR® saddle continuous rooflight is a self-supporting, symmetrical daylight system with different sloping angles. A shed continuous rooflight version is also alternatively possible on request.


The tried and tested sandwich-type construction comprises an aluminium grid framework with semi-transparent fibreglass sheets applied on both sides. Due to its low dead weight of approx. 10 kg/m2, the GRILLODUR® saddle continuous rooflight is excellently suited for roof refurbishment projects to increase the thermal insulation value without additional structural load on the existing substructure. This therefore enables you to achieve a total energy transmission rate of only 28%.

In addition, it is equipped with an integrated smoke and heat exhaust (SHEV) tested according to DIN EN 12101-2. Alongside high safety in preventive fire protection, protection on the roof is also guaranteed - due to a fall-through safe construction and extreme hail resistance.

Due to the various structures of the fibreglass covering layers, the highest demands for sound protection and sun protection combined with glare-free daylight, excellent mechanical values and high chemical resistance are fulfilled.
