Gypsum blocks as installation walls

In accordance with DIN 4109, Para. single-leaf walls to which or in which water installation fittings are secured, must possess a surface-related mass of at least 220 kg/m².

With lighter partition walls it is to be verified with a suitability test that, referred to the transfer of installation noises, they do not have a more unfavourable behaviour than heavy walls. 



For partition walls made from gypsum blocks with elastic connections this verification could take place in investigations by the Institute for Acoustic Insulation for Testing and Research into Building Matters in Hildesheim.
