This European Standard specifies the requirements for factory made products of expanded perlite, with or
without facings or coatings, which are used for the thermal insulation of buildings. The products are
manufactured in the form of boards or multi-layered insulation.
This European Standard also covers composite insulation boards (see Annex D).
This European Standard specifies product characteristics and includes procedures for testing, evaluation of
conformity, marking and labelling.
Products covered by this European Standard are also used in prefabricated thermal insulating systems and
composite panels; the performance of systems incorporating these products is not covered.
This European Standard does not specify the required level of a given property to be achieved by a product to
demonstrate fitness for purpose in a particular application. The levels required for a given application are to be
found in regulations or non-conflicting standards.
Products with a declared thermal resistance lower than 0,20 m2-K/W or a declared thermal conductivity
greater than 0,070 W/(m-K) at 10 ℃ are not covered by this European Standard.
This European Standard does not cover in situ insulation products and products intended to be used for the
insulation of building equipment and industrial installations. This European Standard does not cover the
following acoustical aspects: Acoustic absorption index and direct airborne sound insulation.
