Homasote® 440 SoundBarrier® replaces poured Gypsum Flooring and Resilient Channel by addressing historical modes of failure and inherent system limitations. Homasote® rigid board technology accommodates building movement, so it will not crack like gypsum. Our flooring applications will retain long-term IIC & STC, in less than half the labor and time expense. In demising walls, we add damped mass behind drywall, addressing post installation attachment of televisions and shelving.
Homasote® STC ratings will outlast any Resilient Channel application.
Due to the high field failure rates of resilient channel, many large developers have seen cost as high as $30,000 per unit to remediate noise issues due to RC failure. While using resilient channels is appealing only from a construction cost perspective (ignoring litigation risk,) developers, architects, and builders must be fully aware of the difficult construction requirements, as well as the post-construction failure rate and litigation risk, before still considering using them.
