Beschreibung
Zusammenfassung:	Ventilator cover (1) for exhaust ventilation of roofs in the ridge, hip or arris area, with preferably a plastic ventilator cover body (2) and sealing element (9), the sealing element (9) having a shape approximating that of a wedge in cross section and a sealing element body (10) which consists of plastic foam. To improve sealing properties and to increase the service life of the sealing element (9), an essentially nonporous skin (14) is provided on at least one of the free surfaces (11, 12), preferably on outside surface (11), of the sealing element body (10) so as to cover roughly its entire area. This skin (14) is formed from a structural change of the material of the sealing element body (10) at its surface (11, 12), so that the skin consists of the same plastic as the sealing element body (10), and is permanently connected to it.
