Hacker Floor Underlayments
Product Benefits: Low Profile

To address high-frequency noise, we like to stay low.

Low profile- that is. With FIRM-FILL® SCM-125, Hacker Industries has addressed the need to reduce the transition from sound mat areas to non-mat areas in multi-family construction with this 3mm sound control mat engineered to limit impact sound transmission. Ideal when topped with a non-standard minimum 3/4″ (19mm) thickness of FIRM-FILL® Gypsum Concretes, FIRM-FILL® SCM-125 is a cost-effective way to address minimum IIC requirements while maintaining a minimal profile for your sound control system.
