SIPs - Green Building Solutions

Structural Insulated Panels or SIPs are prefabricated building panels used to frame the walls, roof and floors of a structure. When using SIPs you get the framing and insulation all in one package. The result is a strong, highly insulating and airtight panelized form of construction.


RAY-CORE is a completely different, far superior kind of structurally insulated panel! RAY-CORE’s unique patented wall panels and roof panels are not a “sandwich panel”, relying on OSB and glue to provide the structure of your home. RAY-CORE structural insulated panels use century old tried and true framing practices and have added technology and high-tech materials to form a superior insulating panel with foamed-in-place studs, the highest R-value polyurethane foam and wrapped in a radiant vapor barrier.

What Are Sandwich Panel SIPs?

The most common type of structural insulated panel is referred to as “sandwich panels”. Sometimes referred to as “stressed-skin panels”, these panels generally consist of an insulating material, polystyrene foam, “sandwiched” between two outer “skins” of oriented strand board or OSB. The two materials are laminated together with an adhesive or glue to form a combination panel with the outer skin material providing the “structural” part of the insulated panels. Other variations of insulating and skin materials are occasionally available.
