This insulation material is produced from molten stone, cinder or glass and therefore in a kind of wooly constitution. Mineral wool is distinguished into resilient and non resilient insulation materials. Due to its low thermal conductivity, porous structure and elasticity it is used for thermal insulation, airborne sound insulation, sound absorption and impact sound insulation. The list of building materials ÖE, issued by the Austrian Institute of Construction Engineering (Österreichisches Institut für Bautechnik, OIB), mandates that all mineral wool products have to comply with EN 13162 regarding acoustic and thermal protection. The CE-certification of mineral wool products is necessary, either directly on the product itself or on a label affixed to the product. Performance requirements and regulation concerning their use are stated in ÖNORM B 6000.
