This European Standard specifies the requirements for factory made expanded polystyrene products, with or without rigid or flexible facings or coatings, which are used for the thermal insulation of buildings.
This standard describes product characteristics and includes procedures for testing, evaluation of conformity, marking and labelling. Products with a declared thermal resistance lower than 0,25 m² x K/W or a declared thermal conductivity at 10 C greater than 0,060 W/(mxK) are not covered by this standard.
