Product Details
R2+ BASE is provided in 4' X 8' boards which are erected and fastened in place using common wood working tools and techniques. R2+ BASE provides continuous insulation and a cladding attachment base in one installation. The product is ideal for use under common thin-veneer cladding systems such as sheet metal, metal composite, porcelain, terra cotta, fiber cement, thin brick and cultured stone. R2+ BASE incorporates a kiln-dried, fire-treated plywood, making it a friendly surface for CCW’s membrane air barriers. R2+ BASE has been fire-tested to NFPA 285 and passes this tough test in many wall assemblies.
