British Gypsum Gypframe 70 AS 50 AcouStud 4.2m

The Gypframe 70 AS 50 AcouStud is a sigma-profiled metal stud engineered to suppress sound transmission across wall assemblies whilst preserving usable floor space.

British Gypsum's Gypframe 70 AS 50 AcouStuds integrate seamlessly into 43mm, 70mm, 92mm, and 146mm wall configurations, delivering substantial improvements to acoustic insulation ratings. The distinctive profile dissipates acoustic energy as it passes through the partition, effectively lowering noise levels. Compared to conventional 'C' studs, the extended flange design provides superior rigidity and load-bearing capacity.
