Isofoam South Africa (Pty) Ltd, was established in 1995 by the Kharafi Group of companies, with the aim of introducing IsoBoard Extruded Polystyrene (XPS) Thermal Insulation board to the South African Market. XPS offers the highest commercially available heat flow resistance of all insulation boards. IsoBoard rigid high density thermal insulation boards offer a range of applications from over-purlin to under floor slab to exposed ceilings. Simple to install, IsoBoard is water resistant, flame retardant, washable and paintable, and has the highest resistance to heat transfer. IsoBoard – for comfort and energy efficiency.

Loss of heat through floors on concrete surface beds is experienced as a cold underfoot condition, particularly during winter when the supporting soils cool down due to hygroscopic action of water. In order for rooms to be heated or cooled energy efficiently, the floors need to be insulated from the surrounding soil bed to prevent soilbed from being heated.
Where construction, design and / or cost implications prohibit the installation of an inverted roof insulation system, the requirement for insulation is met by fixing IsoBoard to the under soffit surface of the slab as a ceiling.
