Ventilating arrangement for building roofs

摘要

A ventilating arrangement for building roofs, consisting of a plurality of lamellar, pivotably movably flaps made of heat-insulating material, is improved such that, while maintaining adequate heat insulation in the abutting or overlapping region as well, commercially available plastic panels of appropriate design can be used in the particular application. For this purpose, each flap (1, 1') consists of a rectangular frame comprising two transverse-side bearing plates (3) and two longitudinal-side enclosing profiles (2) connected to the latter. The heat-insulating material has the form of a planar plate (4), the longitudinal-side edge regions of which are received in a sealed manner in the enclosed profiles (2). The longitudinal-side enclosing profiles (2) are profiled at their external, long end faces in such a way that the enclosing profiles, located opposite one another in the closed state, of neighbouring flaps (1, 1') together form at least two chambers which are sealed off to the outside and inside. <IMAGE>
