scope:

NEN-EN 16809-1 specifies the requirements for products of loose-filled expanded polystyrene (EPS) beads and bonded polystyrene beads for in-situ installation in masonry cavity walls and frame constructions. This European Standard is a specification for the insulation products before installation. It describes the product characteristics and includes procedures for testing, marking and labelling. This document 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. This document does not cover factory made expanded polystyrene (EPS) insulation products or factory made or in-situ products intended to be used for the insulation of building equipment and industrial installations. 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 document. This document does not cover products intended for airborne sound insulation and for acoustic absorption applications.
