This European Standard specifies requirements for loose-fill cellulose insulation (LFCI) products for the thermal and/or sound insulation of buildings when installed into walls, floors, galleries, roofs and ceilings.This European Standard is a specification for the loose-fill cellulose insulation (LFCI) products before installation.This European Standard describes the product characteristics and includes procedures for testing, marking and labelling and the rules for evaluation of conformity.Products covered by this European Standard may also be used in prefabricated thermal insulation systems and composite panels; the structural performance of systems incorporating these products is not covered.Products with a declared thermal conductivity at 10 °C greater than 0,060 W/(m  K) or a declared thermal resistance lower than 0,25 m2  K/W are not covered by this European Standard.This European Standard does not specify the required level of all properties to be achieved by a product to demonstrate fitness for purpose in a particular application. The required levels are to be found in local regulations or non-conflicting standards.This European Standard does not cover factory made cellulose products placed on the market as bats, mats or boards intended to be used for the insulation of buildings or loose-fill cellulose products for the insulation of building equipment and industrial installations.
