Styrofoam is the Trade-Name of a range of blue Extruded Polystyrene Foam insulation boards originally developed and marketed by the Dow Chemical Company in the early 1940’s. Unlike Expanded Polystyrene (EPS), styrofoam is manufactured via a continuous extrusion process. All Styrofoam products possess a rigid closed cell structure with very unique properties including low thermal conductivity, high resistance to water penetration and high compressive strength. Styrofoam extruded polystyrene is light weight and easily bonded. All Styrofoam extruded polystyrene products are CFC free! meaning they do not contain Fully Halogenated Chloroflurocarbons (CFC’s) as regulated by the United Nations Environmental Program (UNEP) in the Montreal Protocol. Styrofoam extruded polystyrene products are manufactured at 24 Dow production facilites world over – North America, Eurofe, Middle East, and Japan.
