ABSTRACT:
A panel and frame weatherseal combination is disclosed for sealing the marginal edges of a panel closing an opening defined by a frame, with particular utility for sealing the corner areas thereof. The panel has an exterior surface facing the outdoors. The weatherseal comprises a longitudinally extending backing strip of a generally uniform cross-section throughout its length, to which a plurality of spaced-apart longitudinally extending flexible barrier fins are affixed longitudinally along and transversly extend from the backing strip. The innermost barrier fin extends past the marginal edges of the exterior surface. Any outdoor air movement or the like impinging on the exterior surface presses the innermost barrier fin into sealing engagement with the marginal edges of the exterior surface. At the corners of the panel and frame, the barrier fins are interdigitated to provide an excellent corner seal.
