This European Standard specifies the requirements for factory made products for external thermal insulation composite systems (ETICS) based on expanded polystyrene, delivered as a kit, and used as thermal insulation for buildings. The standard describes product characteristics and includes procedures for testing, marking and labelling. ETICS are applied to external surfaces of new or existing walls and/or soffits to improve the thermal insulation. ETICS include special fittings (base profiles, corner profiles, etc.) to connect them to adjacent building structures (apertures, corners, parapets, etc.). ETICS give protection against weathering and improve the appearance of the buildings. They do not contribute to the stability of the wall and/or soffits on which they are installed. The standard covers systems where the thermal insulation material is required for the load transfer to the substrate. This standard covers systems with a declared thermal resistance equal to or greater than 1 m².K/W. The requirements from national regulations concerning the mechanical resistance and stability of ETICS should be taken into account. This standard does not cover the strength between the ETICS and the building surface to which it shall be fixed, i. e. the substrate.
