This product is used to provide a mid to high level of improvement to thermal insulation. The board is mounted to an extruded polystyrene insulator which has superior resistance to natural elements. It also has a vapour control layer to help minimize condensation which makes it suitable for use around windows and timber frame constructions. For a lower level of insulation, try Gyproc ThermaLine Basic which is perfect for use in bedrooms. For any further information, speak to a member of our sales team today. Gyproc ThermaLine Plus Insulated Plasterboard is only available in tapered edge.
