SFIA member ClarkDietrich has launched SilentXpress™, a new field-assembled sound isolation system. The system creates narrow double-stud (chase wall) assemblies. SilentXpress provides tested and published sound and fire-rated assemblies in a narrower footprint than a traditional chase wall.
The system uses proprietary Type CWSC connectors with ProSTUD® framing to connect adjacent studs under a single track. This configuration reduces sound transmission. The connectors are available in two sizes for a range of project types:
- 3-5/8″ for wall assemblies
- 6″ for wall assemblies
“Sound isolation has long been a challenge that forces project teams to choose between acoustic performance and usable square footage,” says Janine Dallies, category manager, connections, ClarkDietrich. “That tradeoff is especially pertinent across multifamily builds, hotels, hospitals, and offices.”
SilentXpress™ changes that equation. It brings proven acoustic performance to narrower assemblies, all with faster lead times and more efficient shipping than other solutions on the market.
Backed by extensive acoustical testing, SilentXpress demonstrates outstanding sound isolation performance across multiple assemblies. It also offers UL-tested 1-hour and 2-hour fire-rated assembly options.
Because SilentXpress is field-assembled with clips and ProSTUD framing, the system is easily adaptable to real jobsite conditions and provides more flexibility. This can help streamline delivery schedules and minimize potential project delays. Because the SilentXpress components ship compactly in boxes, the system is logistically easier and more cost-effective from the start.
Type CWSC connectors are available for rapid delivery through ClarkDietrich’s Clip Express program, which offers shipping as fast as one day.
