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. A similar cloth strip and bubble can be used to weatherstrip windows, doors, and other building openings by securing the movable member to the window or door frame.
