THERMAPINK® insulation has long-term thermal resistance stability compared to polyisocyanurate foam products. It also provides efficiencies during installation such as "direct-to-steel deck" with no gypsum board thermal barrier needed in most commercial single-ply and metal roofing systems.
Owens Cornings FOAMULAR® extruded polystyrene insulation is an ENERGY STAR® qualified product. Other grades may be available with minimum order quantities.
