Styroboard XPS by Foamex has become the material of choice for home builders, specifiers, architects and engineers due to its high compressive strength and superior thermal performance. Truly a green building product, Styroboard XPS now contains up to 90% recycled expanded polystyrene which has been diverted from landfill.

While expanded polystyrene offers greater flexibility and versatility, extruded polystyrene provides higher long-term R-values and thermal performance. A resilient and robust construction material, Styroboard XPS can be used across a range of building and construction applications – 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, Styroboard XPS still preserves its thermal and physical properties thanks to its high-density cell structure, making it practically impervious to water.

Dimensionally stable, organically inert and moisture resistant, Styroboard XPS meets a number of key requirements in structural and civil engineering. With superior compressive strength and higher, long-term R-Values Styroboard XPS 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.


Fire Properties

All Styroboard XPS products are manufactured from a fire-retardant raw material and do not present as a fire hazard when correctly installed. Like other organic materials, polystyrene will burn when in contact with a flame, but it will self-extinguish when the fire source is removed.


Environmental Properties

Produced with no refrigerants and free from HCFCs, 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.

The sole manufacturer of XPS in Australia

Foamex stands as the exclusive Australian manufacturer and supplier of domestically produced extruded polystyrene, exemplifying its commitment to the local market. Embodying the principles of a true circular economy, Styroboard XPS is crafted from up to 90% premium-grade, recycled expanded polystyrene (EPS). By harnessing this environmentally responsible material, your projects gain a distinct advantage in terms of integrity, safety, and durability, while significantly contributing to sustainability efforts and the preservation of natural resources.

Using Foamex Styroboard XPS, made in Australia for the Australian climate ensures the integrity of your building product. It is important to note that imported extruded polystyrene does not always provide any guarantees about the grade of material used in the manufacturing process. Over time, extruded polystyrene that has been manufactured using low-quality input material has the tendency to rapidly leach out harmful blowing agents, which impacts the environment and affects functionally via reduced R-Values. 

Styroboard XPS is entirely free from Hexabromocyclododecane (HBCD), a flame retardant that was commonly used in polystyrene insulation materials. This omission of HBCD in Styroboard XPS is highly beneficial as it promotes a safer and more eco-friendly solution for insulation needs, ensuring reduced potential for harmful chemical exposure and contributing to the overall improvement of environmental sustainability.

Be sure to ask your supplier whether the extruded polystyrene for your project is Styroboard XPS made by Foamex. If not, make sure you contact us directly.
