Abstract
A passive venting device for venting a building comprising a base comprising (1) a vent structure for permitting gases to pass in and out of the building; (2) an attachment structure coupled to the vent structure for attaching the device; and (3) a gas-permeable screen sized, shaped and positioned to prevent objects from passing through said vent structure, and having an airflow-enhancing configuration for providing greater airflow area than screens of ordinary sloped configuration; and a cover mountable to the base so as to cover the vent structure and permit the free flow of gas. The gas-permeable screen is spaced from the attachment structure in a direction vertically away the roof.
