FIC
Concrete Acoustic Floor
An acoustic airspace is formed by adhering pre-spaced KIP isolation pads to steel channel. This isolated framing platform is a base for either metal decking as a formwork for concrete or to directly attach concrete structural panels.

Testing Results
Note to specifier: FIC is closely related to RIM as both systems use Kinetics Isolation Pads (KIP) as the resilient element. Please consult the RIM concrete tests page and compare with your construction for an approximation of system performance.

Installation Overview
-
RESILIENT INTERFACE
Adhere resilient interface (PPI by KNC) to all penetrations and perimeters. PPI prevents sound vibration from transferring from the isolated slab to the non-isolated structure.
-
POSITION CHANNEL
Place Channel runs per shop drawings.
-
TRIM CHANNEL
Trim ends of and adhere pads as necessary to maintain 4" maximum cantilever. Add optional fiberglass batting between channel.
-
INSTALL DECKING
Follow industry standards, run perpendicular to channel.
-
ADD SEEPAGE PROTECTION
Lay poly sheeting 18" from perimeter, extend over the PPI and temporarily adhere to wall.
-
POUR SLAB
Install reinforcement and pour slab.
-
FINISH PERIMETER
Remove Tear Strip from PPI and seal perimeter gap.
Design Guidelines
- Channels stack tightly and are portable on a jobsite
- Pad and channel spacing can be customized for specific acoustic and/or load requirements
- Can be mechanically fastened to rooftops while maintaining isolation
- Can be used with or without noise absorptive batt
For structures that cannot support the weight of concrete, consider FIC-W which replaces concrete with a wood composite.
