Abstract: A light-framed wall structure contains a wall frame of studs, a bottom plate and a single top plate that together define a stud cavity; exterior sheathing attached to the wall frame and covering the stud cavity; and a polyurethane foam within the stud cavity and affixed to the exterior sheathing, studs, bottom plate and top plate.

Abstract: Prepare a laminated assembly by providing an insulating member comprising a polymeric foam having opposing surfaces and a structural member by positioning the structural member so as to extend over at least one of the opposing surfaces of the insulating member and providing a moisture-curable hot-melt polyurethane or silicone adhesive having an open time and an application temperature range and disposing the adhesive between the insulating and structural members at a coating weight of 16 grams per square meter or less and three grams per square meter or more while at an application temperature and then pressing the structural and insulating members together during the open time of the adhesive.

Abstract: Structural insulation sheathing (SIS), preferably in the form of a panel, comprises a structural member and an insulation member. The structural member and insulation members are in intimate, planar contact with one another, and the SIS structure meets both the structural (that is, AC 269) and insulation (R>2) requirements for the North American residential market. The structural 23 member of the SIS structure is multi-layer laminated paperboard. The insulation member of the SIS is a foamed sheet of a thermoplastic material such as polyisocyanurate.
