ÖNORM EN 17139

This European Standard specifies the requirements for factory made vegetal fibres based products (VFBP), with or without facings or coatings and with or without integral reinforcement, which are used for thermal insulation of buildings. Products are manufactured in form of rolls, felts, slabs or boards. Products covered by this standard may also be used for acoustic applications. The standard also covers multilayered boards and slabs and composites insulation boards and slabs. Products covered by this standard are also used in prefabricated insulating systems and composites panels. The structural performance of systems incorporating these products is not covered by this standard. This European Standard applies to any thermal insulation products made of at least 70 % of vegetal fibres per mass with or without the addition of bonding agents or bonding fibres and/or additives and which don’t fall within the scope of the EN 13171. It does not replace the existing procedures for the determination of the declared properties of products already covered by an existing harmonized standard. This 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 regulations or non-conflicting standards. Products with a declared thermal conductivity at 10 °C, greater than 0,08 W/(m.K) or a declared thermal resistance lower than 0,20 m2/k/W are not covered by this standard. This European Standard does not cover in situ applied insulation and products intended to be used in the insulation of building equipment and industrial installations.
