In order to improve the energy efficiency of an existing building, it is necessary, among other things, to improve the thermal insulation provided by that building’s external walls. If the additional insulation required for this cannot be fitted on the outside, then it will need to be applied on the inside instead. To avoid the need for complex designs, insulating materials with a considerably reduced susceptibility to damage should be used, for example the mineral insulation panel Multipor. Xella Technologie‐ und Forschungsgesellschaft mbH has conducted a study in cooperation with Xella Deutschland GmbH to determine whether, and if so, how, Multipor affects structure‐borne sound transmission when used as interior insulation. The study, the results of which are presented in this article, involved testing flanking sound transmission in a laboratory at the Hochschule für Technik (HFT) in Stuttgart, Germany.
