The ventilation grilles that we use with the K-Vision PremiDoor are versatile, which means that the ventilation grille has various advantages. Read more about the specifications here.
The ventilation grille is thermally interrupted, which means that there is no transfer of cold from outside to inside. Thanks to the self-regulating valve, there is a maximum supply of fresh and healthy air without any draughts. A punched inner profile is also used, which keeps mosquitoes, flies and other unwanted insects out. This gives the grid good insect resistance.
