Update from Foamex regarding COVID-19
Foamex - Innovative Polystyrene

Styroboard XPS extruded polystyrene sheets are strong and durable, making it an ideal product for use across a range of construction and building applications - both residential and commercial.

A resilient and robust construction material boasting a high compressive strength and a superior thermal performance, Styroboard XPS is the number one choice for home builders, specifiers, architects and engineers.

The high-density cell structure of Styroboard XPS also makes it practically impervious to water. When insulation comes into contact with water it loses its thermal abilities; but even when facing extreme weather conditions, Styroboard XPS from Foamex preserves its thermal and physical properties, making it the preferable choice for building materials.

Product Uses

Floor Insulation: The high compressive strength of Styroboard XPS makes it ideal for insulating a wide range of floor constructions, especially those subjected to heavy loads such as warehousing, production areas, and car parks. Styroboard XPS can absorb local peak loads as well as adjust to uneven surfaces under pressure. Dimensionally stable, it will also not attract vermin and is resistant to most ground contaminants.

Perimeter Insulation: Styroboard XPS is ideal for perimeter insulation - surrounding the shell of a building without forming any thermal bridges. Perimeter insulation helps a slab retain warmth, further reducing the amount of heat lost through the building's foundations. Suitable for use in pervious, semi-pervious and impervious soils, Styroboard XPS extruded polystyrene sheets deliver excellent thermal insulation. Its R-values will also help increase your Energy Efficiency Rating (EER) for a relatively low expenditure.

Inverted Roofs: As an insulation layer fitted over the waterproofing seal to help protect the membrane from fluctuations in weather conditions, Styroboard XPS extruded polystyrene sheets are durable, do not rot or decompose. Its high compressive strength makes it an ideal insulation material for roofs subjected to heavy loads or constant foot traffic.

Styroboard XPS and the environment

Thanks to a revolutionary new manufacturing process Styroboard XPS extruded polystyrene sheets from Foamex are also environmentally friendly. Produced with no refrigerants and HCFC free, Styroboard XPS is a truly green building product. With Styroboard XPS you can limit external temperature influences, reduce internal temperature fluctuations, and in turn, reduce the need for mass air-conditioning and electricity consumption.

Maintaining thermal consistency means less energy is consumed, which leads to fewer greenhouse emissions.
