ABSTRACT:
A vent, together with one or more building apertures, provides a route for gas exchange through a building surface. The vent comprises a base member having a vent aperture therethrough and a generally planar mounting flange on its perimeter. The base member may be mounted within a building surface such that the mounting flange extends between an internal building surface layer and one or more external building surface layers and the vent aperture is in fluid communication with the one or more building apertures. The vent also comprises a vent cover which is removably mountable to the base member when the base member is mounted within the building surface. The vent cover has a hood member which projects downwardly and outwardly from the base member for conveying moisture away from the vent aperture. A bottom drainage flange may project outwardly and downwardly from beneath the vent aperture to convey moisture downwardly and outwardly past an outermost one of the one or more external building layers.
