Sto-InnoDrain is an insulation board of expanded polystyrene according to EN 13163 with a drainage effect. Sto-InnoDrain is used as a facade insulation board intended for outdoor use, in StoTherm Vario D or in other StoTherm facade systems exposed to moisture. The board should be glued or plugged and glued on the facade. Sto-InnoDrain is manufactured by heating polystyrene grains, containing approximately 5% pentane, with steam. The polystyrene grains expand until they contain 98% of air. The pre-expanded polystyrene will first be dried, before mixing with additional materials. The EPS-mixture is thereafter dried and moulded under compression. After the stabilization phase, the products are ready for packaging and labelling. Sto-InnoDrain boards which dont pass the quality control at the production site, are recycled into new Sto-InnoDrain boards. Sto-InnoDrain is provided in several thicknesses. The average density of Sto-InnoDrain boards with thickness between 30 mm - 200 mm is approximately 23 kg/m³. Weight per declared unit is 0,759 kg with density of 23 kg/m³ and thickness of 33 mm. Please use the conversion table in this EPD, page 4, for other thicknesses then the declared unit.
