What Are RAYCORE Structural Insulated
Panels ® ?

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 air barrier.  

For code purposes, RAYCORE Structural Insulated Panels - SIPs, with integrated studs, are considered conventional framing and fall under the provisions of the IRC Section 6, when applicable to wall framing. (Section R610 does not apply, as RAYCORE SIP’s are not a “Sandwich panel” style SIP as defined by the IRC and regulated by that section.) As one building code official put it... "... basically a code complying stud wall filled with foam!! Easy-peasy!"

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’, 116 5/8", 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)! *

RAYCORE's state of the art polyurethane foam insulation has the highest insulation values per R-value inch and at the lowest cost per square foot than any other insulated panel on the market.  Click here to see how RAY-CORE SIPs insulation compares and outperforms any other insulation on the market.
