Extruded Polystyrene (XPS)

Extruded polystyrene (XPS) is a high performance rigid foam board insulation with high compressive strength. Extruded polystyrene is especially useful in under soffit/car park applications but can also be used for cavity walls, roofs and other types of flooring.

Composite Global Solutions (CGS) supply two varieties of XPS:

• Goldfoam standard XPS, used in Australia for over 10 years
• CGS OPD-zero – blown with CO2, it has zero Ozone Depletion Potential.

Satisfying Section J

Our extruded polystyrene products are specified in a range of applications to assist complying with Section J of the Building Code of Australia. Our extruded polystyrene boards are most often used in under soffit insulation applications as a thermal barrier for the conditioned spaces above and adjacent to carparks and similar areas. XPS is versatile and can also be used to effectively insulate cavity walls, roofs and other flooring.

Easy to Handle and Install

Extruded polystyrene is rigid, has a high compressive strength, yet remains lightweight, easy to handle and cut to requirements. XPS is easily installed, usually with an adhesives and fastening pins.

Safe and Healthy

Extruded polystyrene is closed cell foam, meaning it is resistant to moisture and vapour penetration. In other types of insulation (especially expanded polystyrene), moisture penetrates in between the “bubbles” of the insulation and invites mould, as well as the general deterioration of the insulative properties of the product. Extruded polystyrene does not share this weakness.

Economical and Effective

Extruded polystyrene retains its shape and thermal conductivity values over time without using external faces or other enhancements.

Composite global is able to supply Goldfoam XPS and CGS-ODP zero at very competitive rates. We specialise in the satisfaction of Section J and the needs of owners and specifiers in sourcing premium quality products with the unparalleled service and advice.
