Steel-Con’s Serenity-RC-Plus was professionally sound tested at Riverbank Acoustical Laboratories, one of the leading and longest-standing acoustical testing facilities in the United States. Acoustical testing for the STC performance of Serenity-RC-Plus proved the product’s ability to provide high-end sound performance for both steel and wood framed assemblies, well above other high-end RC products available.
Testing
Riverbank Acoustical Laboratories
Sound assemblies are constructed, thoroughly inspected, and then certified by Riverbank Acoustical Laboratories. NVLAP accredited for ASTM E90 & E413, ISO Certified.
Riverbank Acoustical Laboratories is accredited by the US department of commerce, National Voluntary Laboratory Accreditation Program (NVLAP Lab Code 100227-0) to ISO 17025:2005 laboratory quality management and specific acoustical test standards.
SSA Acoustics
SSA Acoustics, a leader in engineering acoustics and multi-family residential design for 17 + years, has conducted extensive testing and research on Steel-Con’s Serenity Resilient Channel.
SSA’s team of acoustical consultants and lab technicians tested Serenity-RC-Plus for isolation efficiency and in-field performance. When comparing the results gathered to those of other products within the industry, the team found that Serenity-RC-Plus is the superior product for reducing airborne transmission in walls and ceilings for both wood and steel assemblies.
Serenity-RC-Plus consistently measured better than its competitors in isolation and efficiency tests, both critical to obtaining elevated STC (Sound Transmission Class) performance. SSA’s group of highly-qualified consultants continue to research, develop, and test the product to ensure it meets all required sound specifications.
Serenity-RC-Plus Brochure
The all-around performance of Serenity-RC-Plus impressed Bill Stewart, the managing partner of SSA Acoustics:
The superior performance of Serenity-RC-Plus in lab and field testing is un-matched. Recommended as our basis of design in all resilient channel applications”
Profile Features
Serenity-RC-Plus has been engineered, with help from the acoustical community, to include the following features that reduce sound transmission through the assembly.
Material Composition
- D-20 material
- 57 ksi min. yield strength
- 65 ksi min. tensile strength
- G40 galvanized coating
- ASTM A653/A653M
Slot and Hole Pattern
- 1¼” x 5/16″ Slots
- 3/16″ (#8 Screw) Holes
- Slots and holes are aligned to increase the path that sound must travel through the assembly
- 2” Slot spacing along the channel allows for wall and ceiling framing at almost any spacing conditions including the typical 12” o.c, 16” o.c, and 24” o.c
Stiffening Ribs
- 1/16″ Raise stiffening ribs
- Creates separation and air space between sheathing and framing stud
- Only 2 points of contact between sheathing and framing stud, decreases area for sound transmission
Serenity Knurling
- Stiffens attachment flange to create gap between sheathing
- Aids in positive screw attachment through thin acoustical steel profile
