ABSTRACT:
A ventilator cap (1), made of plastic, for ventilation of roofs in the ridge, hip or arris area, with a fastening area (2), with an edge area (3) and with an intermediate area (4) connecting the fastening area (2) and the edge area (3) with one another, in which intermediate area has air passage openings (5, 6) and edge area (3) has an elastically flexible sealing element (7) extending over the length of the cap on its roof-facing underside, and the sealing element (7) has the structure of a fine-fiber brush with a carrier part (8) and a plurality of elastic brush fibers (9) placed in at least as flowtight a packing as possible. The effect of the weather conditions on the brush fibers (9) is substantially eliminated, specifically, by placing at least one protective element (10) that influences the elasticity of the brush fibers (9) as little as possible on the outside of sealing element (7), i.e. on the side facing away from the roof.
