Application
Secured to wood-frame construction (e.g., joists, trusses), Model ICW
incorporates a one-inch (1") rated deflection spring in series with a
neoprene cup to resiliently support one or more layers of gypsum board.
The unique design of the Model ICW bracket allows the isolator to be installed
on the joists to optimize ceiling height. A channel clip/leveling rod
assembly is designed to carry a single piece of 1-1/2" x 1/2" 16-gage
steel carrying channel. Drywall furring channel is attached to the carrying
channel. The system provides the installer with a means for leveling the
isolated ceiling framing. Gypsum board attaches quickly and easily thanks
to a preload spacer that holds the isolator rigid until the weight of
the gypsum board compresses the spring. Incorporate Model ICW into any
isolated ceiling design where one-inch (1") rated spring deflection and
minimal reduction in ceiling height are needed for superior performance
coupled with low-profile design.
Benefits
- Maximum natural frequency of 4.4 Hz under lightest
typical load conditions.
- STC 76, IIC 62 with Model ICW attached to 2" x 10"
joists and suspending two (2) layers of gypsum board with 3-1/2” fiberglass
batt in airspace.
- Multiple features incorporated into the design ensure
inexpensive installation.
- Spring/neoprene cup combination improves performance
against low-frequency noise.
- Actual installed load can vary between 75% and 150%
of rated load without significant impact to ceiling performance.
