What Are RAYCORE Structural Insulated

RAYCORE Structural Insulated Panels (SIPs) are a unique, component structural insulated panel. RAY-CORE SIPs ™ rely on integrated structural members or studs to provide the structural integrity of the building. Superiorly insulating high-density closed-cell polyurethane foam insulation is injection molded to provide the highest insulation R-value per inch in the Structural Insulated Panel market.  The panel comes wrapped on either side with a low-perm foil radiant barrier.

The panels consist of conventional #2 or better Douglas Fir or SPF 2x4, 2x6 or 2x8 studs, configured 16” or 24” on-center. 

Other stud configurations including 12” on center staggered studs for those requiring a thermal break, and panels with no studs are available in a variety of sizes and corresponding R-values. Additional options include Select Douglas Fir,  engineered lumber — LSL and LVL studs, borate pressure treated studs, and fire treated studs.

Standard panel lengths include 92-5/8”, 8’, 104-5/8”, 9’, 10’ and 12’.

Based on the thickness of the panel, superior R-values are achieved with minimal panel thickness—2x4 (R26), 2x6 (R42) and 2x8 (R52)!
