- An insulating nail base designed for use in commercial construction above-grade wall applications. The product consists of a coated-glass-faced rigid polyisocyanurate insulation board of various thicknesses factory-laminated to a 5/8" fire-treated plywood facer. It is provided in 4' x 8' boards which are erected and fastened in place using common wood working tools and techniques. It provides continuous insulation and a nail base in one installation. The product is ideal for use under common thin-veneer cladding systems such as stucco, corrugated metal and fiber cement siding. It incorporates a kiln-dried, fire-treated plywood, making it a friendly surface for CCW's membrane air barriers. It has been fire-tested to NFPA 285 and passes this tough test in many wall assemblies. Carlisle provides R2+ BASE Insulating Nail Base, R2+ accessories and CCW air/ vapor barrier membranes for a complete wall weatherization system.
