Application
Secured to concrete, metal deck, or structural framing, Model ICC incorporates
a one-inch (1") rated deflection spring in series with a neoprene cup
to resiliently support one or more layers of gypsum board. Attachment
can be direct to concrete or metal deck, or it can be suspended from threaded
rod that is properly anchored. 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 ICC into any isolated ceiling
design where one-inch (1") rated spring deflection and a ten-inch (10")
airspace are needed for superior performance.
Benefits
- Maximum natural frequency of 4.4 Hz under lightest
typical load conditions.
- STC 84, IIC 70 with two (2) layers of gypsum board
suspended under a 6-inch concrete slab (75 psf) 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.
