RAY-CORE SIPs ® Polyurethane Foam Insulation

This custom blend of polyurethane foam not only produces some of the highest R-values *, it has a low perm rate and will not retain or allow moisture to pass through it so no problems with condensation or mold and mildew.  It also ensures an airtight structure.  Further, it produces all of these benefits while maintaining a Class 1 fire rated standard.  Class 1 means that the foam will not sustain a flame.  Far, far superior to polystyrene foam, RAY-CORE’s quality control standards will not settle for less.
