APPLICATION OVERVIEW

Important issues when specifying an external wall insulation solution include the level of thermal performance to be achieved, which finish is the most suitable and the Reaction to Fire classification of the insulation.

EWI (External Wall Insulation) is used on an existing building where there is no cavity to insulate, significantly improving thermal performance and reducing energy bills.

EWI involves the installation of an insulating layer to the external fabric of an existing, or new building, and is usually finished with a render coat, brick slips or clad with timber boards or tiles.

WHY MINERAL WOOL?

  • Using a breathable mineral wool solution allows moisture vapour to pass through the construction to outside, removing the risk of condensation.

  • Mineral wool solutions are non-combustible and have the best possible A1 Euroclass Reaction to Fire classification.
