Applications

• High-performance FOAMULAR®150 Extruded Polystyrene XPS Rigid Foam Insulation
• Retards the transmission of water vapor and moisture in masonry walls
• Provides continuous insulation over steel stud framing, in insulated concrete sandwich panel walls, or in masonry unit cavity walls, or when used with non-penetrating, surface mounted furring systems over masonry or concrete walls
