Document Type and Number:
Japanese Patent JP5745398
Kind Code:
B2
Abstract:
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
