Polyfoam Floorboard Super is a rigid, lightweight extruded polystyrene (XPS) insulation. The Super grade offers high compressive strength for use in applications of intensively loaded industrial floors. In addition to lambda values as low as 0.034 W/m·K, the thermally efficient foam boards are also robust and moisture resistant, making them suitable for basement walls and floors, swimming pool basins and perimeter insulation below DPC.
