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
- Commercial building: insulation including inverted roofs, suspended ceilings, below slab and within the cavity wall
- Agricultural: XPS can be used as internal lining of roofs, ceilings or walls for poultry sheds, mushroom farms and wineries.
- Storage: Cool rooms, cold storage floors and refrigeration.
- Construction: residential and commercial including under slabs/floors, roofs, walls, decks and balconies.
