Extruded Polystyrene is a closed cell polystyrene rigid foam board, with high compressive strength and excellent long term thermal resistance performance, due to its inherent resistance to moisture transfer. It is produced on a continuous, fully automated extrusion process. In South Africa, it is manufactured in a single density range, suitable for most local applications.

Boards are available in various lengths and thicknesses to suit most residential, commercial, agricultural and industrial thermal insulation requirements, including under floor slab, cavity wall, over purlin and rafter, inverted roof and insulated ceiling applications. Polystyrene will deteriorate if continually exposed to ultra violet radiation, and will dissolve in solvents. Compatible with all water-based adhesives and paints.
