British Gypsum Gypframe 70 AS 50 Acoustuds 3.0m

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

British Gypsum Gypframe 70 AS 50 AcouStuds accommodate 43mm, 70mm, 92mm, and 146mm wall configurations, delivering substantial improvements to acoustic insulation characteristics. The specialist profile dampens sound as it propagates through the wall structure, effectively reducing noise levels. Compared to conventional 'C' studs, the extended flange provides superior load-bearing capacity and dimensional stability.
