The package of standards comprises the following group of interrelated standards for the specifications of factory made thermal insulation products; all of which come within the scope of CEN/TC 88: EN 13162, Thermal insulation products for buildings — Factory made mineral wool (MW) products — Specification EN 13163, Thermal insulation products for buildings — Factory made expanded polystyrene (EPS) products — Specification EN 13164, Thermal insulation products for buildings — Factory made extruded polystyrene foam (XPS) products — Specification EN 13165, Thermal insulation products for buildings — Factory made rigid polyurethane foam (PU) products — Specification SIST EN 13164:2013

1 Scope This European Standard specifies the requirements for factory made products of extruded polystyrene foam, with or without facings or coatings, which are used for thermal insulation of buildings. The products are manufactured in the form of boards which are also available with special edge and surface treatment (tongue & grooves, shiplap etc.).
Products covered by this standard are also used in prefabricated thermal insulating systems and composite panels; the performance of systems incorporating these products is not covered. This standard describes product characteristics and includes procedures for testing, evaluation of conformity, marking and labelling. The 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 0,25 m²⋅K/W or a declared thermal conductivity greater than 0,060 W/(m⋅K) at 10 °C are not covered by this standard. This standard does not cover in situ insulation products, nor products intended to be used for the insulation of building equipment and industrial installations (covered by EN 14307), or civil engineering applications (covered by EN 14934). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
