ETICS and EPS: Building Insulation and Safety Considerations in Europe
External Thermal Insulation Composite Systems (ETICS) incorporating Expanded Polystyrene (EPS) insulation are used in projects to renovate and improve building envelopes. They can be relevant to the policy objectives of the Renovation Wave and to the technical requirements applicable to construction projects. Learn more about the technical characteristics of ETICS and the factors relevant to building thermal performance and fire safety.
Technical Characteristics and Building Performance
ETICS is a building-envelope system that combines insulation with other components, such as adhesives, base coats, reinforcement and finishing layers. When correctly designed and installed, an ETICS can contribute to the thermal performance of an external wall. Its effect on heat transfer, thermal bridges, energy use and greenhouse-gas impacts depends on the complete building design, system specification, installation, climate, operation and energy source.
ETICS with EPS can be used in residential and commercial renovation projects where the system meets the technical requirements of the application. Building-energy outcomes should be assessed for the specific building and renovation scenario. In the context of the European Renovation Wave, EUMEPS contributes sector information on ETICS and EPS insulation applications.
Safety Standards and the Role of the European Association for ETICS (EAE)
Building safety, including fire performance, must be assessed at system level. An ETICS with EPS must be specified, installed and used in accordance with the applicable product documentation, system design, fire-performance classification and national building requirements. The performance of the system depends on all of its components and the conditions of its use; it should not be inferred from the insulation layer alone.
The European Association for ETICS (EAE) supports dialogue on technical information, good practice and relevant requirements for ETICS. Its work contributes to the exchange of information among stakeholders involved in the design, specification and installation of ETICS.
ETICS and EPS in Building-Renovation Projects
ETICS with EPS can be considered in building-renovation projects where its technical characteristics meet the requirements of the building system. EUMEPS and EAE contribute to discussions on technical performance, safety requirements and regulatory developments affecting ETICS applications in Europe. Environmental and energy-related outcomes should be assessed for the complete building system and the specific use scenario concerned.
