Extruded polystyrene (XPS) foam is rigid foam providing a strong, yet lightweight and flexible insulation solution which is resistant to water absorption, making it ideal for a range of building and commercial applications

Description:

Extruded Polystyrene Board is ideal for a range of uses – from wall and ceiling insulation, cool rooms & refrigeration, under concrete slab (i.e. car park), and even for architectural modelling or hobby model making. Extruded Polystyrene is the ideal insulation material for houses and commercial applications.

Applications:

  • Housing Insulation: Including underslab, cavity wall, decks and balconies
  • Roofing Insulation: XPS Insulation can be positioned either at the top of the roof or as internal insulation below the roof structure
