Do materials for impact sound insulation under screed require European technical approval?

Materials for impact sound insulation under screed require European technical approval (ETA) at a European level, as the following applies:

They are neither subject to a harmonised standard nor is there a mandate for such.
Furthermore, an ETA would also be required if:

  • They deviate significantly from the harmonised standards,
  • There is a mandate for a harmonised standard, then an ETA could be granted for a fixed period.

Countries that subscribe to an ETA:

Austria, Belgium, Cyprus, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, ‚Italy, Latvia, Lithuania, Luxembourg, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey, United Kingdom.

Building products that have an ETA must be annotated with the CE mark. 

The ETA serves as proof of the suitability and safety of building products for their intended purpose. The ETA extends to the following characteristics:

  • Mechanical strength and stability
  • Fire protection
  • Hygiene, health and environmental protection
  • Safety in use
  • Sound insulation
  • Energy saving and heat protection

The ETA is awarded by EOTA. The European Organisation for Technical Approvals is the organisation that forms the basis for building product guidelines, in which the posts named by the EU countries and the EFTA countries participating in the EEA agreement for granting European technical approvals are represented.
