ABSTRACT:
A ventilating element with a ventilator cap for mounting on the ridge, hip or arris area of a roof, and which has at least one elastically flexible sealing member that extends along a longitudinal edge area of the cap. The sealing member is formed as a looped filament seal. This configuration has the advantage that undesirable de-orientations of the filaments are prevented. This is because the loop structure has no free filament ends, and there is always a curvature in the end region which, on the one hand, prevents unintentional back-hooking, and on the other hand, imparts a certain coupling effect to adjacent loops, so that overall interlinking and interlacing of the individual loops are present, benefitting each other, especially by holding one another down, and preserving a close, flow-tight packing. The loop filament seal is formed of filament material having an elasticity which ensures the sealing function is established by placing the individual filaments on top of one another, by overlapping them and so forth.
