SilentXpress™ Sound Isolation System
Quote requiredNarrower than traditional chase wall assemblies
SilentXpress™ is a field-assembled, narrow double-stud wall system engineered to achieve high acoustic performance while minimizing wall depth. Utilizing proprietary Type CWSC connectors with ProSTUD® framing, the system connects adjacent studs beneath a single track to reduce sound transmission and create a space-efficient alternative to traditional chase wall assemblies. Designed as a space-saving alternative to conventional double-stud or chase walls, SilentXpress provides comparable or improved STC performance in a slimmer profile—making it ideal for multifamily, hospitality, healthcare, and commercial applications where both acoustics and floor space are critical. Key Features: U.S. Patent No. D1,098,899
