Abstract: Membrane roofs are susceptible to damage in high winds. Wind can lift a membrane roof from a building and cause it to tear or become damaged. The present roof vent prevents liftoff and damage by reducing the air pressure under the membrane during high winds. The present roof vent has two opposed convex domes separated by a gap. Wind blowing across the roof flows between the domes where it accelerates and creates a region of low pressure according to the Venturi effect. The lower dome has an opening at the gap so that the low pressure is applied to the space under the membrane roof. Therefore, when wind blows across the roof, the vent draws air from under the membrane and the membrane is pressed against the roof, preventing liftoff.

Abstract: The automatic vent damper has various embodiments of a wind actuated vent system, which automatically closes to preclude entry of wind blown water when a wind of predetermined velocity and direction acts upon the device. The damper may be installed as an off-ridge or ridge vent system, or in other operating environments and installations as desired. Various mechanisms are used to operate the device, with all including one or more springs, which hold a rigid door or flap, open in light wind conditions. However, when a wind of sufficient velocity blows toward the vent opening, the door or flap is closed due to aerodynamic forces thereon to preclude entry of wind blown water into the device. The door or flap automatically opens again due to the spring mechanism when the wind abates.

Abstract: The present invention provides a solar-powered ventilation system for an attic or rafter space that mimics the appearance of the roofing material and thus has little effect on the appearance of the building.

One or more vent openings in the secondary vent and an opening in the primary vent conduct air between the attic or rafter space and the outside. In certain preferred embodiments, a solar-powered fan is also preferably located underneath the secondary vent.

The ridge vent includes a main body portion having a pair of eaves and a neck portion. The neck portion includes a plurality of projections on opposing inner walls thereof to maintain a minimum predetermined spacing between the inner walls and the nailer board, to thereby create airflow paths around opposing sides of the nailer board. A pair of weather blocking panels are secured to the nailer boards to help block rain, snow, etc. from entering though openings in the eaves. Each weather blocking panel includes a laterally extending portion with a plurality of slots and an upwardly extending edge portion. The upwardly extending edge portion creates a venturi effect over the slots to help draw air out therethrough when wind is blowing over the upwardly extending edge portions.

Abstract: A ridge vent assembly extends along the ridge of the roof of a building structure and is provided with multiple plies of corrugated material. The corrugations of the plies define small diameter passages that communicate a vent opening cut along the ridge of the roof with ambient atmosphere. A flexible member consisting of a strip of cloth material extends along the outer edge of the vent parts. The strip of material terminates into a flexible bubble. When wind speed increases above a predetermined wind speed, the movable member moves into a position adjoining the edge of the vent parts and the bubble is compressed against the upper edge of the corresponding vent part, thereby preventing entry of wind driven moisture and snow into the passages and into the building structure through the vent opening. Accordingly, the cloth strip and bubble act as a weatherstripping material for the vent.

Abstract: In accordance with the present invention, there is provided a new and inexpensive ventilating system for greenhouses using rigid plastic, glazing panels that are thin, lightweight, and quite long. This is achieved by bending outer ends of the glazing panels and lifting to create vent openings. This method takes advantage of the inherent flexibility of these glazing panels to bend them to shift between open and closed positions without the use of a conventional, separate hinged, framework section. Particularly, in accordance with the present invention, an actuator is connected to a flexible bendable portion of the elongated, rigid glazing panel and the actuator lifts and bends an end portion of the panel, which has an inherent flexibility unlike glass or thin films and which has a memory and an elasticity, such that the panel wants to return to its normal unflexed position, which is the closed position, in the preferred embodiment of the invention.

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.
