SIP Walls | Structural Insulated Panels

Structural Insulated Panels (SIPs) are a high-performance building system for residential and light commercial construction. The panels consist of an insulating foam core sandwiched between two structural facings, typically oriented strand board (OSB). This system offers superior and uniform insulation compared to more traditional construction methods.

Thermocore Structural Insulated Panels are high-quality polyurethane foam core panels suitable for exterior wall applications in residential and commercial settings. Thermocore wall panels are entirely structural and can replace conventional framing in most applications. Due to their custom manufacturing, Thermocore panels offer extensive design flexibility.

Insulating Core

Polyurethane Foam Core

3-1/8" or 5-1/2" closed cell polyurethane foam core with a minimum core density of 2.2 and a true Class 1 fire rating. Unlike EPS, polyurethane foam will not melt when exposed to heat. Additional properties include:

• Compressive Strength: 26 psi
• Tensile Strength: 18 psi
• Shear Strength/Modulus: 22/300 psi
• Porosity: 95%
• Will not promote the growth of mold
• Serves as its own vapor barrier
