This EPD describes an insulated sheet of expanded polystyrene according to EN 13163 with a drainage effect. Sto-InnoDrain is a draining insulating disc with excellent energy performance, high safety and great flexibility. The insulating board has several unique properties; it is drainage, diffusion open, pressure equalizing and fire rated.
Sto-InnoDrain is made up of polystyrene grains which are allowed to expand until they comprise 98% of small air bubbles. Polystyrene is then coated with a water repellent coating, gluing together the points of contact. The result is a continuous pore system that both insulates well and drains water well. The insulating board is also treated in a way that makes it difficult to ignite and is self-extinguishing.
Sto-InnoDrain can be used as a part of the system StoTherm Vario D - a drainage facade insulation system that in combination with StoGuard becomes two-stage sealed. StoTherm Vario D is the ideal solution for those who want a compact facade system and who want to use a light insulating material with good insulating value, good drainage capacity and documented fire safety.
Sto-InnoDrain is a façade insulation board intended for outdoor use, as insulation board in StoTherm Vario D or as insulation board in other StoTherm systems exposed for moisture. The board should be glued or plugged and glued.
