Extruded polystyrene insulation boards, with a cementitious topping for use on inverted roof constructions.
An HFC blown CFC/ HCFC-free cementitious topped extruded polystyrene board with shiplap ends and tongue and groove sides. The product provides a lightweight solution to inverted roofing systems in low wind uplift locations. It can also be employed in exposed situations, such as up-stands as a self protected insulation board, in conjunction with Roofmate TF-X or TF-A on the horizontal areas. The calculated thickness of insulation should be increased by an additional 20% to take account of the cooling effect of rain water run-off.
