Foamex StyroTherm Extruded Polystyrene Sheets (XPS Insulation)

Foamex StyroTherm XPS Insulation Boards

Due to its high compressive strength and superior thermal performance, Foamex StyroTherm XPS Insulation boards have become first choice for many builders, specifiers, architects, and engineers. Extruded polystyrene (XPS) provides higher long-term R-values and thermal performance compared with expanded polystyrene (EPS) which offers more flexibility and versatility.

StyroTherm XPS Insulation by Foamex – Key Benefits

• Durable and sturdy for long lasting applications
• Lightweight and easy to handle
• High compressive strength
• Long-term retained R-value
• Australian made and manufactured
• Environmentally friendly – HCFC free

Who manufacturers XPS Insulation in Australia?

In Australia, Foamex is the only manufacturing plant to make and sell Extruded Polystyrene (XPS). StyroTherm XPS made by Foamex is made for Australian climates and ensures a high level of integrity for your building product. Additionally, this product complies with Australian Building Standards AS1366.4 and has a KPA rating that exceeds BCA regulations.

What is XPS Insulation?

As the name suggests, XPS foam is formed with polystyrene polymer and manufactured using an extrusion process that results in a rigid insulation material with a dense, close-knit cell structure.

The manufacturing process for XPS is similar to the process used to create expanded polystyrene (EPS) foam products. Polystyrene is a synthetic, hydrocarbon polymer derived from benzene and ethylene. Polystyrene resin beads or granules are fed into an extruder, where they are heated at very high temperatures until molten. At this stage, additives are added to the mixture including colouring agents. Note that XPS products are often identifiable by a distinctive colour associated with a product brand.

A foam blowing agent is then added to enable the product to expand after extrusion. Using controlled heat and pressure, the plastic mixture is forced through a die (extruded), after which it is allowed to cool and expand into the desired shape. The resulting foam board is cut to the final product dimensions. Click here to learn more about XPS insulation.

Environmental properties of Foamex StyroTherm XPS

Produced with no refrigerants and free from HCFCs, StyroTherm XPS is a truly green building product. With StyroTherm 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.
