General information on EPS

   

EPS properties

The properties of EPS insulation materials for buildings and their test methods are defined in EN 13163, which is mandatory since 13 May 2003 for all EU countries.  EN 14933 is the relevant standard for civil engineering applications. Further standards are under development, such as for installed equipment. These harmonised European standards include of a list of properties and test methods, both for general and for specific applications.

The manufacturer declares the properties of the specified product, and is allowed - after initial type testing by a notified body and taking into regard the conformity rules in EN 13172 - to put CE marking on the product. Compliance with 'local' building regulations is based on the performance level of the finished product and determined individually  by each EU country.

An overview of a number of EPS properties per EPS type according to EN 13163 is given in the following table.

For specific applications the producers are prepared to develop product types that suit these applications perfectly.
