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.
Claims18
A roof vent, comprising:
- a base portion configured to rest upon a roof deck, the base portion including a first opening;
- a top portion comprising a second opening, the top portion positioned above the base portion;
- a cavity formed between the base portion and the top portion;
- a fire-resistant mesh material disposed within the cavity,
- wherein a flow path is formed from a first region below the roof deck, through each of the first opening, fire-resistant mesh material, cavity and second opening, to a second region, the second region positioned above the roof deck and the top portion, and wherein the mesh material provides a net free ventilating area with greater than about 80% open area and is configured to substantially prevent the ingress of floating embers into the top portion.
