Abstract (en)
[origin: EP0454900A2] The invention relates to a roof ventilator (D), which is designed as a roof-covering slab (1) and has a central, cupola-shaped dome (2) which in its height is greater than its width and smaller than its length, and proposes, in order to obtain a solution which is favourable structurally and in terms of ventilation, that the vertex region of the dome (2) constructed as the end piece of a ventilation connection pipe (6) is designed as a ventilation grating (7). <IMAGE>
