TESTING

Riverbank Acoustical Laboratories Sound assemblies are constructed, thoroughly inspected and then certified by Riverbank Acoustical Laboratories. NVLAP accredited for ASTM E90-09 & E413-10, 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 SCAFCO’s Serenity Resilient Channel.

SSA’s team of acoustical consultants and lab technicians tested Serenity-RC 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 is the superior product for reducing airborne transmission in walls and ceilings, for both wood and steel assemblies.

Serenity-RC 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.

The all-around performance of Serenity-RC impressed Bill Stewart the managing partner of SSA Acoustics:

SERENITY-RC

Serenity-RC is a premium product and the best cost effective solution for reducing the transmission of airborne sound through walls and ceilings. By separating the drywall from the stud flange, the channel minimizes the direct path by which sound travels through the framing, as detailed on page 3.

SCAFCO’s Serenity-RC 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 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.

Serenity-RC

"The superior performance of Serenity-RC in lab and field testing is un-matched. Recommended as our basis of design in all resilient channel applications”

Serenity-RC

Serenity-RC has been engineered, with help from the acoustical community, to include the following features that reduce sound transmission through the assembly.

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 seperation 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

Serenity RC Assembly

Serenity-RC with Wood Framing Serenity-RC effectively isolates drywall from wood studwork and substantially weakens sound waves traveling through them.

Attaching Serenity-RC in wood applications is nearly effortless and will provide superior STC ratings beyond other resilient channel products on the market.

Serenity-RC Channel must be installed per specifications of the USG Drywaller’s Handbook, ASTM C754 “Installation of Steel Framing Members to Receive Screw Attached Gypsum Panel Products”, and SCAFCO’s Manufacturer Instructions.

A full list of SCAFCO’ s installation instructions for steel and wood assemblies can be found at www.SCAFCO.com, or by contacting Technical@SCAFCO.com.

The following details illustrate important installation considerations:

Installation Instructions

Wall Assemblies:

• Install Serenity RC horizontally and space 24” o.c to match the laboratory test data.

• Install Serenity-RC channel to wood or steel studs 2” from floor and within 6” from top of wall, with steel/wood fasteners providing sufficient anchorage. The attachment flange shall be installed below face of channel for all rows except bottom row which will be inverted.

• Allow 1/4” gap from resilient ceilings, and 1/8” minimum gap for acoustical calk around all other edges. Do not rest gypsum board on floor, intersecting walls, or ceilings.

• Cabinets or other wall hung items mounted on resilient channel walls cannot be attached through to the studs. Utilize toggle bolts if gypsum board is adequate for strength, if not utilize different acoustical assembly.

Serenity-RC

General Requirements:

• For single layer drywall assemblies utilize 1” long framing screws for attachment to resilient channel flange. For attachment through two layers use 1 5/8” long fasteners.

• DO NOT fasten through resilient channel flange and into wall/ceiling studs. Longer fasteners will result in short circuit and reduced performance of the resilient channel. See detail C.

Ceiling Assemblies:

• Attach Serenity-RC perpendicular to the ceiling joists

24” o.c. for joists 16” o.c.; 16” o.c. for joists 24” o.c.

For multiple layers of Gypsum Board decrease spacing of resilient channel. Spacing should be decreased in conjunction with the weight of boards/materials added, to provide sufficient anchorage and load distribution.

• Allow 1/8” gap for acoustical calk around all edges. Do not rest edge of boards on adjacent walls or ceilings.
