STRONG-R COMMERCIAL STRUCTURAL INSULATION
STRONG-R is the ultimate in performance and protection to shield commercial buildings from the outside elements—heat, cold, air and moisture with a structural component equivalent to lateral sheer properties of WSP. The continuous wall insulation covers gaps in traditional building insulation, to increase energy efficiency in the long term. And the lightweight design compared to other sheathing products makes installation efficient, saving you time and money.
• Closed cell polyiso foam with foil front and rear facers and fiber glass foam core for best in class
R-value and moisture resistance including WRB code compliance.
• Multiple design thickness to meet energy code requirements, cost efficiently.
• Structural component equivalent to lateral sheer properties of WSP.
• Complies with ASTM E84, ASTM E119 and NFPA 285 assemblies
