Universal protective ventilation grille – 1000/60mm

Description

Its function is the same as that of a simple ventilation grille; it merely increases the cross-sectional area of the air intake. It is used: where there are increased technical requirements for ventilating the space between the roof cladding and the vapour barrier, in cases where, for technical or aesthetic reasons, the cornice is boarded up to the upper edge of the counter-battens.
