In the course of the two-and-a-half year research project Schutz.aufs.Dach, HFA together with TGM and several industrial partners, is investigating the airborne and rain noise insulation of wooden roofs with roof top insulation. The insulation materials, the coverings and various construction details will be varied. The aim of the project is on the one hand to investigate the correlation between airborne and rain sound insulation of the roofs and on the other hand to improve the roofs in this regard. At the end of the project, planners will be provided with the developed roofs and determined sound properties by a freely available component catalog.
