Marmox Multiboards are CE marked insulation boards which can be used internally or externally. They are sheets of rigid extruded polystyrene insulation encased between two thin layers of fibre reinforced concrete which provide a space-efficient alternative to laminated plasterboard. They are available in several thicknesses from 10mm to 60mm.
