    Thermocore Structural Insulated Panels are high-quality foam core panels suitable for exterior wall and roof systems in residential and commercial applications. Designed to enclose timber frame structures, log structures and conventional buildings, this one-piece product is completely structural and can substitute for conventional framing in most applications. Because they are custom-manufactured, Thermocore panels allow extensive design freedom.

    Basic Composition

    Each panel is composed of a polyurethane insulation core with interior and exterior skins of oriented strand board. Panels are precisely custom-manufactured to drawings through a foam injection process in which the polyurethane bonds directly to the skins. They include pre-installed corners, door bucks, window bucks, subfacia and electrical conduit boxes. Pre-engineered header and beam pockets are molded into panels.

    Physical Properties

    Overall Thickness: 6-7/16″, 8-1/4″ (+/- 3/8″)

    Inner/Outer Skin: 7/16″ oriented strand board. All OSB is exterior-rated and is APA/Teco-rated for structural use

    Insulation Core

    2.2 lb. density, Class 1, closed-cell foam. Contains no formaldehyde or CFCs. Self-adhering polyurethane foam is injected between the skins to ensure a consistent, superior bond and structural integrity. The foam exhibits these properties:
