Styrofoam – The original Extruded Polystyrene (XPS) product

STYROFOAM™ has been manufactured by Dow since the 1940s. The process of extruding foamed polystyrene results in a material with uniformly small, closed cells, a smooth 'skin' and an unrivalled set of properties which make it the choice of specifiers in a wide range of demanding insulation applications.

Dow Chemical, the leading XPS manufacturer has developed new technology to significantly improve the thermal resistance of Styrofoam. This has resulted in a new product type called XENERGY™ Styrofoam.
