The Steinodur PSN SDP board is a thermal insulation and drainage, hydrophobized board made of hard polystyrene foam. It is used for thermal insulation of facades, foundations, basement walls, plinth. On one side the PSN steinodur panel has profiled drainage grooves for draining ground ducts to the drainage system. The other side of the board has embossed grooves to form a fine square mesh ensuring excellent adhesion of plaster in and glue in. Each board has a rim on the periphery giving a secure and tight connection without allowing thermal bridges to form.
