Survey results: Experiences with internal thermal insulation

Survey about internal insulation

In the autumn of 2016 RIBuild conducted an online survey amongst practitioners in the construction industry to gain knowledge about their practical experiences with internal thermal insulation. The survey shows a need for knowledge about thermal internal insulation and how to handle the biggest challenge which concerns vapour barriers and humidity.
