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.
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
greater than 0,060 W/(m x K) at 10 C are not covered by this standard.
