This standard specifies the requirements applicable to factory-made mineral wool products, with or without facings or finishing coatings, intended for the thermal insulation of buildings and manufactured as felts, boards or slabs. It defines their characteristics, as well as testing, conformity assessment, marking and labelling, without setting the levels required for a particular application, which are governed by regulations or non-conflicting standards. It also covers their use in insulation systems and prefabricated composite panels, without defining the performance of those systems. Excluded are products having, at 10 °C, a declared thermal resistance of less than 0.25 m²·K/W or a declared thermal conductivity greater than 0.060 W/(m·K); insulation products installed in situ covered by EN 14604-1 and -2; and products intended for building equipment and industrial installations covered by EN 14303.
