With our plastic frames we supply ventilation grilles that have various advantages. Read more about the benefits of our ventilation grilles here.

The ventilation grilles that we use with our plastic frames with the Gealan S9000NL profile have a self-regulating flap as standard. This means that the valve reacts to varying pressure. In addition, our ventilation grilles are insect repellent and you have various options when selecting the color of the ventilation grille. The color options are: Clear anodized (F1), White (RAL 9010) and Cream white (RAL 9001).
