Extruded polystyrene sheets (XPS) are thermal insulation boards that are both strong and durable, making it an ideal product for use across a range of construction and building applications and wall cladding insulation for building construction – both residential and commercial.  When insulation comes into contact with water it can have an adverse effect on its ability to thermally insulate; but when faced with extreme weather conditions, XPS polystyrene still preserves its thermal and physical properties thanks to its high-density cell structure, making it practically impervious to water.

The XPS boards are waterproof, resilient and robust construction material boasting high compressive strength and superior thermal performance. The Foam Company's XPS boards can be used for both internal and external wall insulation. They are a vital insulation product under heated floors and under-slab in cool stores. They are ideal for under-roof insulation in housing, sheds and commercial and industrial buildings.

Dimensionally stable, organically inert and moisture resistant, XPS polystyrene panels meet a number of key requirements in structural and civil engineering. With superior compressive strength and higher, long-term R-Values when compared to traditional expanded polystyrene, XPS polystyrene is suitable for use on floors subjected to engineered loads and constant traffic, as well as insulation for inverted roofs, rooftop gardens, parking decks and as commercial purlin roof spacers. XPS is the number one choice for home builders, specifiers, architects and engineers - also a superior and premium product for model making and craft.
