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.

What is claimed is: 1. A weatherproofing system for use in construction of a building with a wall with a rough opening there through for receiving a window unit having a frame with a flange thereabout, an exterior surface of said wall being a substrate for a weatherproofing membrane and said flanged window unit, said weatherproofing system comprising, in combination:a rear seal having a foam web with two major surfaces, said foam web being self-setting with a predetermined recovery rate, said foam web selected from a group consisting of an open cell structure, a dosed cell structure, and a structure of open and closed cells, said rear seal disposed in said rough opening to compressively fill, upon emplacement of said flanged window thereon, the cavity between said flanged window unit and said rough opening precluding the entry of water, water vapor and air, said rear seal, in turn comprising:a pressure-activated adhesive layer disposed on one of said two major surfaces of said foam web, said adhesive layer having sufficient tack to, upon pressure activation to durably adhere said rear seal to said substrate and form a sealed bridge between said window flange and said weatherproofing membrane;a front seal having two major surfaces, said front seal selected from a group consisting of a foam web, a polymeric tape, and a metal foil, said front seal, in turn comprising:a flange cover portion adapted, upon installation, to cover the exterior surface of said flange of said window unit;a rear seal cover portion adjacent to and contiguous with said flange cover portion, upon installation, covering the rear seal portion extending beyond said flange of said window unit;an extension portion adjacent to and contiguous with said rear seal cover portion, adapted, upon installation, to be disposed on said substrate;a rear adhesive layer disposed on one of said two major surfaces of said front seal, said adhesive layer having sufficient tack to, upon pressure activation to durably adhere said front seal to said flange, to said rear seal and to said substrate; and,a front adhesive layer disposed on one of said two major surfaces of said front seal, said front adhesive layer being opposite said rear adhesive layer said front adhesive layer, upon pressure activation to durably adhere said front seal to said weatherproofing membrane.
