This application relates to ventilation systems, more particularly to roof ventilation systems that help to protect buildings against fires. The roof vent has an ember impedance structure that impedes the entry of flames and embers or other floating burning materials while still permitting sufficient air flow to adequately ventilate a building. Several configurations of vents employing baffle members and fire-resistant mesh material are described, which can substantially prevent the ingress of floating embers and flames.
L'invention porte sur des systèmes de ventilation, plus particulièrement sur des systèmes de ventilation de toit, qui aident à protéger des bâtiments vis-à-vis d'incendies. L'exutoire de fumée comprend une structure de blocage de braise qui empêche l'entrée de flammes et de braises ou autres matériaux de combustion flottants tout en permettant un écoulement d'air suffisant pour ventiler de manière adéquate un bâtiment. Plusieurs configurations d'exutoires employant des éléments de déviation et un matériau en treillis résistant aux incendies sont décrits, lesquels peuvent empêcher sensiblement l'entrée de braises flottantes et de flammes.
