Polystyrene is one of the most common plastics produced and used in buildings for insulation. It can either be EPS (expanded polystyrene) or XPS (extruded polystyrene). The choice is dependant on the application. XPS has a higher compressive strength, resists moisture more, and has higher R-values than EPS.
Polystyrene is used under concrete floors, in walls, and on rooftops. It is supplied in different thicknesses and lengths depending on the application.
Apart from our standard sizes, we can also cut special sizes and shapes on request. *
