R2+ SILVER is a rigid foam insulation board designed for use in commercial construction above-grade wall applications to provide continuous, high R-value insulation. The product is composed of a closed-cell polyisocyanurate foam core bonded on both sides to a composite foil "tri-laminate" facer. R2+ SILVER can be installed on the exterior or the interior side of the wall assembly. R2+SILVER is offered in different thicknesses, sizes and foam core densities. It is secured in place with fasteners, adhesive or a combination of the two. Installation technique depends on the wall assembly. R2+ SILVER has been fire tested to NFPA 285 and passes this tough test in several wall assemblies, CCW provides R2+ SILVER insulation, R2+ accessories and CCW air/vapor barrier membranes for a complete wall weatherization system.
