Insulated SIP Roof Panels and Wall Panels

Utilizes Conventional Framing Practices

RAYCORE SIP roof panels and SIP wall panels combine three labor tasks into one smart panel system. This system utilizes conventional proven building materials: premium Douglas fir members, state-of-the-art foamed in place rigid polyurethane foam, and foil radiant barrier. This brilliant panel coupled with jobsite materials will meet all local standard building codes.

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.)  No special code, No special ICC reports required.
