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.
