Abstract: An eve air vent includes upper and lower panels joined at their upper edges, and spaced apart at their lower edges to form a wedge shape. Longitudinal ribs are sandwiched between the upper and lower panels to form inlets at the lower edge, and air passages between the panels. Large outlet holes are provided on the lower panel. The vent is installed between the shingles and plywood sheathing of a roof, with its lower edge flush with the eve. A strip of plywood sheathing is removed, or left out during roof construction, to create a hole aligned with the outlets on the bottom of the vent. Air is thus able to enter from the outside environment through the inlets at the lower edge of the vent, and pass through the holes in the plywood sheathing into the attic. The vent is installed without modification to the eve, and it does not protrude beyond the eve, so that it does not mar the appearance of the eve.

Abstract: A ventilating device for a home or other building includes a frame for covering a ventilating opening in the structure. The frame defines a passage for communicating the ventilating opening to the atmosphere. The passage contains a freely movable valve member which normally rests in an inactive position under gravitational force to permit venting through the passage. The valve member moves in response to wind pressure to an active position in which the member seats against a seating surface within the passage to prevent entry of wind-driven precipitation into the structure. When the wind subsides, the valve member returns under the force of gravity to its inactive position.

Abstract: A one-piece continuous roof drip edge vent comprising an upper planar section a middle louvered section and a lower section. The upper section extends up an inclined roof so that a starter row of shingles is not necessary, the lower section abuts the horizontal facia board and the middle section which is perpendicular to the lower section is continuously louvered to facilitate air inlet venting along the entire roof drip edge.

Abstract: A continuous vent in the form of a resilient apertured trough which fits into a bevel in the center of the soffit or at the fascia or the wall. The advantages of the vent is that its hold is based on its shape, its resilience and the angle of the bevel in the soffit. The vent is used in existing soffits or on new construction. The method involves the steps of venting a soffit by cutting two beveled ends a few inches apart and inserting a resilient apertured vent in the space between the bevels. For new construction, one beveled strip is temporarily adhered via an adhesive to hold the vent in place until the second bevel is completed and both beveled pieces are installed.
