Building Codes

R-Control SIPs are a strong structural system consisting of Foam-Control® EPS (expanded polystyrene) insulation laminated between sheets of structural sheathing. This simple sandwich forms an amazingly strong structural panel for building walls, roofs and floors.

With their versatility, strength, cost effectiveness, and energy efficiency, R-Control SIPs are ideal for a wide range of residential and commercial projects. R-Control SIPs open the door to virtually unlimited design possibilities; putting you in control of your building system, not the other way around. And every R-Control SIP is custom made according to your specifications and drawings, so you get exactly what you need for your project.

Proven to meet, or exceed, building codes.

SIPs meet code requirements R-Control SIPs have been extensively tested by nationally recognized laboratories. R-Control SIPs have been proven to meet or exceed all structural and fire code regulations, greatly reducing your liability exposure. For 30 years, R-Control SIPs have shown they’re the strongest, most reliable, and effective SIPs available anywhere.

R-Control SIPs are heavyweights against the destructive agents of mold, mildew and termites. The Foam-Control EPS in our R-Control SIPs is treated with Perform Guard termite protection. And the entire SIP, when treated with FrameGuard®, prevents mold, mildew and termite damage to its wood components.
