Wedge Boards are manufactured from high density extruded polystyrene with a specially formulated reinforced cementitious surface coating. The boards are manufactured with pre-determined falls of min 1%.
The insulating property of the extruded polystyrene provides excellent thermal insulation and is CFC, HCFC, and HFC free. The tough surface coating provides the perfect surface for the application of tiles. Creating accurate falls over long runs is easily achieved by using standard Delta Thermal Construction Boards as a raising course.
