Structural panel with exterior insulating foam layer

Abstract

A method for installing a multi-layer panel product for use as structural sheathing. The panel product comprises a base manufactured-wood structural panel, such as OSB or plywood, with a factory-applied foam layer affixed to the exterior or outward-facing surface. The foam layer provides thermal resistance as an insulation layer. The foam layer also may act as an air and bulk water barrier. The foam layer may be expanded polystyrene (XPS) foam sheets. The panel product is installed on a structure with the nail or fastener head penetrating the exterior foam layer to sit on the OSB surface, but with minimal or no damage to the exterior foam layer around the area of penetration. The penetration may also be covered or sealed with sealant tape or a liquid-applied sealant.
