Thermal insulation products for buildings - Factory made composite products - Specification
This European standard specifies the requirements for factory made composite products to be used for
thermal insulation of buildings, such as composite insulation products with at least two different thermal
insulation layers and with or without facings or coatings, and composite products with thermal insulation
layer/s bonded to additional external layer/s of non-insulation products.
Products defined by standards EN 13162 to 13171 and prEN 16069 shall be used for the thermal insulation
layers. If a product other than those defined in above standards is used as one of the thermal insulation
layers, then its properties declared for the composite shall be assessed according to test methods and
principles in above mentioned standards.
This standard does not cover the performance of prefabricated systems incorporating these composite
products.
This standard specifies product characteristics and includes procedures for testing, evaluation of conformity,
marking and labelling.
This 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.
Self-supporting building products and products for structural use are not covered by this standard.
This standard does not cover in-situ composite insulation products, composite products for civil engineering
applications and composite products intended to be used for thermal insulation of building equipment and
industrial installations.

European foreword
This European standard (prEN 16491:2018) has been prepared by Technical Committee CEN/TC 88
“Thermal insulating materials and products”, the secretariat of which is held by DIN.
This standard is currently submitted to the CEN Enquiry.
This standard has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential characteristics of EU Regulations.
For relationship with EU Regulations, see informative Annex ZA, which is an integral part of this
standard.
The reduction in energy used and emissions produced during the installed life of insulation products
exceeds by far the energy used and emissions made during the production and disposal processes.
