Paroc stone wool is a versatile thermal insulation for insulating the ground. Stone wool has built-in energy efficiency, fire, sound and moisture safety. Paroc stone wool insulation does not burn and protects other building materials from ignition. The choice of insulation material is of great importance for the general fire safety of a building. As our stone wool is non-combustible (Euroclass A1), there are no restrictions on the use of our stone wool in flat roofs. Make sure that additional used materials, in the build-up, also are compliant with local regulations by visiting local Paroc country sites.
