SilentXpress™ Sound Isolation System

SilentXpress™ is a space-saving, field-assembled acoustic wall system that delivers high STC performance in a narrower profile, helping maximize usable floor space without compromising sound control.

Quick Actions:

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:

  • Narrower than traditional chase wall assemblies
  • No bridging or bracing required
  • Ideal for use in multi-family, offices, hotels, hospitals
  • 1HR & 2HR UL assemblies
  • Published STC tests
  • More flexible than pre-assembled systems
