Adhere resilient interface (SRP by KNC) to all penetrations and perimeters. SRP prevents sound vibration from transferring from the isolated slab to the non-isolated structure.
Place Channel runs per shop drawings.
Trim ends of and adhere pads as necessary to maintain 4" maximum cantilever. Add optional fiberglass batting between channel.
Minimum of two layers, staggered and cross lapped.
Follow flooring manufacturer’s installation instructions.
Trim SRP and seal perimeter gap.
For added acoustic performance and load distribution, consider FIC-C which substitutes the wood composite for concrete.
