British Gypsum Gypframe 70 AS 50 AcouStud 3.6m

The Gypframe 70 AS 50 AcouStud features 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 suit 43mm, 70mm, 92mm, and 146mm wall configurations, delivering marked improvements in acoustic insulation ratings. The specialised profile dampens sound energy as it passes through the wall structure, effectively lowering noise levels. Compared to conventional 'C' studs, the expanded flange design provides superior load-bearing capacity and dimensional stability.
