GracoEZSpray is a two component water-blown liquid spray system. This system cures to a low density polyurethane insulation material. Since it is a open cell it is designed to provide good thermal performance, air impermeable insulation, and an integral part of an air barrier assembly. The foam is also tested to be class A (or class 1) fire rated foam, and meets the ICC-ES AC377 requirements. This open cell foam will provide great performance in residential and commercial/industrial applications, only if temperatures are between -40F-200F.
