The material is used for protection of fire-fighting barriers, technological openings and building construction materials used in industrial, agricultural and housing construction. It has a high fire-fighting effect at a minimum thickness of the used layered material. The application of the method allows the "average descent" of the fire-fighting material with the help of melting keys. This allows the multiple use of the material and retains the architectural-decorative outlook of the protected constructions. The layered fire-fighting material is built at least in three layers: an aluminium folio, a glass tissue and a mineral layer at the following proportion of their thickness: from 0.4:2.0:0.2 to 1.5:10.0:0.8. It tests two options for arrangement of the individual layers: A - aluminium folio, glass tissue, mineral layer at proportion of their thickness from 0.2:0.4:2 to 0.8:1.5:10.0 and B - aluminium folio, glass tissue, a mineral layer, glass tissue, aluminium folio at proportion of their thickness at 0.2:0.4:2.0:0.4:0.2 to 0.8:1.5:10.0:1.5:0.8.
