Abstract
A sealing gasket for use attached preferably to the topmost edge of gypsum board when used as construction wallboard. The gasket includes a support leg section capable of being mounted in engagement with preferably the uppermost edge of the gypsum board. The gasket includes a sealing leg extending outwardly from said leg section which includes an intumescent component to facilitate sealing between the edge of the gypsum board and the wall structure above. In one embodiment the sealing leg includes an intumescent impregnated paper material covered with a structurally enhancing layer. An adhesive layer can be included to attach the gasket to the gypsum wallboard. The sealing leg in this embodiment has an 'A' or 'P' profile and will extend upwardly and inwardly over the upper edge of the gypsum board at an obtuse angle with respect to the support leg for sealing thereabove in the head-of-wall area.
