GRILLODUR®-Insect Protection System

For uninterrupted ventilation – day and night


The new insect protection system for GRILLODUR®-continuous rooflight flaps provides effective protection against the ingress of insects, leaves and coarse soiling during day-to-day ventilation. It is both inconspicuous and permeable to air so that ventilation can take place without restriction.


In combination with the DSG-fall-through protection, the insect screen can be easily assembled in the flap frame and is immediately ready for use.


Due to the weather-resistant fibreglass fabric, you can benefit in the long term from this high-quality insect protection system, which is mainly utilised in hygienically demanding sectors, particularly in the foodstuff, beverage and pharmaceutical industries, as well as in residential and administrative buildings.
