DuPont™ Styrofoam™ Brand Freezermate™ Extruded Polystyrene Insulation is an XPS foam insulation solution designed for use as subfloor thermal insulation in low-temperature applications. These rigid foam insulation boards have smooth, high-density skins; excellent insulating characteristics; high resistance to water and water vapor; excellent freeze-thaw resistance; superior compressive strength; and long-term durability. Because they resist even severe forms of moisture penetration, they offer long-term R-values superior to other types of thermal insulation in freezer and cooler construction. Proven to provide thermal and moisture protection for energy-efficient cold storage, DuPont™ Styrofoam™ Brand Freezermate™ Extruded Polystyrene Insulation also can be used in most static and dynamic loading situations for flooring applications.
