22mm Polystyrene insulated plasterboard is 9.5mm gypsum plasterboard bonded to a 12mm Polystyrene insulation board. The polystyrene is CFC and HCFC-free (zero ODP - Ozone Depletion Potential). This grade of plasterboard should be used where a basic level of additional thermal insulation is required.Board size - 22mm x 1200mm x 2400mm (2.88 m²)Product Description:Polystyrene insulated plasterboard linings provide good fire protection owing to the unique behaviour of the non-combustible gypsum core when subjected to high temperatures,Gyproc WallBoard - 0.19W/mK,Expanded polystyrene - 0.040W/mK,Reduce the risk of condensation and mould growth,The gypsum surface designated Class 0 fire rating,The gypsum surface designated Class 1 surface spread of fire rating,Zero Ozone Depletion Potential (ODP),Global Warming Potential (GWP) <5,Lightweight,Provides internal drylining and insulation in just one fixing operation, giving faster completion times,Provides an ideal surface for plaster skimming or jointing.
