XPS foam can even be used beyond commercial, industrial, and residential structures. Due to its excellent resistance to moisture, imperviousness to rot, mildew and corrosion, controlled compressive strength, and ability to maintain insulating power, XPS foam is a premiere insulating material for critical civil engineering uses as well. Other applications include pipe insulation, marine use, floral and arts and crafts, utility lines, and agricultural uses. Finally, XPS can be used asĀ GeofoamĀ and applied as insulation beneath highways or airport runways.
