ABSTRACT:
A weatherproofing system for installing windows and doors is described and has a front seal and a real seal. The seals include clear, pressure-activated adhesives and seal against attaching hardware. The rear seal has a is self-setting foam web and molds to the flange of the window unit. When installed, the foam is compressed between the inner window frame and rough opening and between the window flange and the wall surface adjacent the rough opening. The system extends beyond the flange of the window unit and receives the weatherproofing membrane thereover. The weatherproofing system acts as a sealed bridge between the membrane and the window unit precluding entry of air and water. Both the foam and the adhesive have fire retardants in the formulation thereof. The rear seal is provided in a tape form with a self-skinned foam layer and a sheet form with polymeric covering web.
