Multilayer vent attached together by filter members

Abstract

In one embodiment of the invention, a building ventilation system is provided that is configured to be mounted on a sides of a building structure between rainscreen wrap and exterior siding of the building for venting air in a gap between the rainscreen wrap and the siding ventilation system. The ventilation system includes a vent part including a plurality of vent passages, a longitudinal direction of the vent part configured to be mounted in substantially horizontal orientation at top and bottom edges of the sides of the building structure and a plurality of non-linear cross members extending between each ply. The plies and cross members define the vent passages, and includes at least two tiers or rows of vent passages. The passages run in a substantially vertical orientation to facilitate venting and draining of the gap.
