US 2026/0098404 A1 · Continuous Insulation Sheathing for Construction

Abstract

The present invention generally relates to insulation sheathing in interior or exterior wall constructions for residential and business applications. More specifically, the invention pertains to an improved insulation sheathing (IS) system such as a wall sheathing (IWS) system that prevents waterproofing failure, mold, mildew, and wood rot, associated with conventional wall constructions. Particularly, this invention relates to insulation sheathing combined with a weather-resistive barrier that allows for drainage of moisture in wall construction applications. The product may be used as continuous or non-continuous insulation sheathing. In one embodiment, this invention relates to a first IS panel, such as an IWS panel, used for construction purposes, comprising the following layers: an insulation facer layer having an outer surface and an inner surface; a first insulation layer having an outer surface and an inner surface; and a weather-resistive barrier (WRB) layer having an outer surface and an inner surface; wherein the inner surface of the first insulation layer is planarly and contactably attached to the inner surface of the insulation facer layer; wherein the inner surface of the WRB layer is secured to the outer surface of the first insulation layer through an adhesive layer; wherein, the WRB layer exceeds the dimension of the first insulation layer from at least one of its edges to create an extension flap; and wherein the extension flap of the WRB layer further comprises a removably attached release-liner attached to the extension flap portion of the WRB layer's inner surface.
