You don't want to screw through … It’s a relatively straight-forward proposition to achieve an STC 50 on a 25-gauge stud wall, but if the wall requires shear strength or structural load capacity, then the gauge size and spacing become a major hindrance. An analytical model for the axial load capacity of cold-formed steel wall stud with sheathing on one or two sides has been developed, with the sheathing simplified as continuous elastic support to the stud. After all there are organizations that have done tests on thermal conductivity and fire resistance rating of such assembly. Wall height is nominal height plus 1 1/8". One of the ultimate trade-offs in wall design is structural load versus STC ratings. The energy industry is faced with a tumultuous landscape of challenges that include rising costs and increased market volatility. If an STC of 50+ is needed for the load-bearing wall, this would represent a significant cost and schedule savings over traditional construction techniques.
