Rockal Foam (28:31) Kg/m³

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.
