STRUCTURAL INSULATION SHEATHING

摘要

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 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.
