Detailed Specs
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 preinstalled corners, door bucks, window bucks, subfacia and electrical conduit boxes. Pre-engineered header and beam pockets are molded into panels.
Physical Properties
Overall Thickness
- Thermocore wall SIPS 4″ (When combined with 1/2″ drywall, accepts standard window jambs.) Structural wall 4 1/2″
- Roof 6 7/16″ (+/- 1/16″)
Inner/Outer Skin
- 7/16″ Oriented strand board (a structural, exterior-rated composite board).
Insulation Core
- Class I closed-cell polyurethane foam with a 2.2 pound density and thicknesses of 3 1/8″ Thermocore panel wall, 3 9/16″ structural wall and 5 9/16″ roof polyurethane. 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:
- Compressive Strength: 26 psi
- Tensile Strength: 18 psi
- Shear Strength/Modulus: 22/300 psi
- Porosity: 95%
- Does not promote the growth of mold.
- Serves as its own vapor barrier.
Minimum R-Value
- Wall: R-24, 26
- Roof: R-40
Fire Safety
- Foam Fire Rating: Class I
- Flame Spread: 20 (ASTM E-84)
- Smoke Developed: 300 (ASTM E-84)
- Structural Integrity: Polyurethane foam is a thermoset plastic which does not melt and maintains structural integrity until consumed.
Warranty
- Thermocore panels carry a limited lifetime warranty covering defects in materials and workmanship.
