British Gypsum Gypframe 146 AS 50 AcouStud 3.6m

The Gypframe 146 AS 50 AcouStud is a sigma-profiled metal stud engineered to suppress sound transmission through partition systems whilst preserving usable floor space.

These British Gypsum studs suit 43mm, 70mm, 92mm, and 146mm partition configurations, delivering substantial improvements to acoustic insulation ratings. The specially developed profile attenuates sound as it passes through the partition structure, lowering noise levels effectively. Compared to standard 'C' studs, the extended flange provides superior rigidity and load-bearing capability.
