RAY-CORE'S Structural Insulated panels (SIPs) are Pre-Insulated Wall, Roof, and Header Systems that combine three labor tasks into one: polyurethane, studs & foil radiant vapor barrier. Together these systems become a fortress that is proven to resist the elements, reduce utility costs, and improve the living enviorment. These SIPs offer a R-Value of up to R-52.

By Incorporating the cutting and spacing of studs with superiorly tight polyurethane insulation, RAY-CORE SIPs are fast to install, which decreases labor costs significantly. These SIPs are reliably square, straight and plumb, with no bending, bulging, or sagging, and are remarkably easy to handle. With RAY-COREs high R-values and tight joints it yeilds phenomenal savings in energy costs over the life of the structure. Simply put, there are no substitutes.
