ABSTRACT:
A vent provides a route for gas flow through a building envelope. The vent comprises a substantially hollow cover member having a cover member surface which defines a vent passageway. The vent may comprise a substantially hollow adapter member. The adapter member is coupleable to the cover member at its exterior end and to a conduit at its interior end to provide fluid communication between the vent passageway and the conduit. The vent may comprise a screen which extends across the vent passageway. The screen has a deformable bend and a plurality of surfaces which secure the screen to the cover member without using separate fasteners. The vent may comprise a damper member with an exterior surface having a profile that conforms to the contour of a portion of the cover member surface.
