The metal insulation support DSH-M 30 is perfectly suitable for fastening pressure resistant insulation materials onto concrete and solid masonry such as natural stone, solid brick and solid sand-lime-brick. The DSH-M is not flammable according to DIN EN 13501-1, class A1. In case your insulation material is softer simply use the metal insulation support DSH-M in conjunction with the metal insulation plate DSH-T 80 in order to obtain a larger contact surface.
