Rigid Foam Board: Styroboard™ Extruded Polystyrene Sheets by Foamex

Styroboard™ extruded polystyrene sheets (XPS) are the Foamex take on a rigid foam board for versatile applications. Foamex wears the distinction of being the industry leader in insulation, within the building and construction industry. The Australian-owned and operated company has developed Styroboard™ as their flagship product - a testament to their hard work and dedication to quality since 1982.

Styroboard™ XPS In Production
Foamex channels more than 35 years of expertise into the production of Styroboard™ XPS. The manufacturing process harnesses no less than high-grade raw materials, innovative building methods, and the latest technologies to seal performance and sustainability into a rigid foam board.

Styroboard™ XPS is manufactured from solid beads of polystyrene resin, without using refrigerants like chlorofluorocarbon (CFC) or hydrofluorocarbon (HCFC) that deplete the ozone layer. The granules are first combined with additives in an extruder. Then, the mixture is melted until a viscous liquid is achieved. The volume of the beads expands upon the injection of a blowing agent. While subjected to controlled heat and pressure, the mixture is forced through a die. Ultimately, a rigid foam board is produced, ready for cutting into various shapes and sizes as Styroboard™ XPS.

Styroboard™ XPS In Action
Styroboard™ XPS scores highly across the board, for key requirements in structural and civil engineering. Water resistance is one such requirement that is of top priority in insulation. Upon contact, moisture weakens the thermal performance of insulation materials. Styroboard™ XPS is designed to prevent water ingress with its high-density cell structure. Even when exposed to harsh weather elements, the rigid foam board maintains its dimensional stability, compressive strength, and long-term R-values. In addition, the extruded polystyrene sheets do not rot or decay and attract vermin, Foamex ensures Styroboard™ XPS will deliver exceptional, long-lasting service.
