QuietRock® 545

Key Benefits

1-3/8” sound damped panel with added mass for low frequency attenuation
Highest performing sound reducing gypsum panel available, delivering maximum sound isolation across a broad frequency range for both high and low frequencies
High reliability—it cannot be easily short circuited like resilient channel. Continues to reduce noise even when fixtures are installed, such as shelves or cabinets
Ideal for high-end home theaters, studios, commercial theaters, mechanical rooms, and other situations where low frequency noise and vibration require sound isolation
Outperforms other sound attenuation methods, including multi-layered assemblies, resilient channel, and soundboard
Can achieve a 2 hour fire-rating with a single layer application in certain wall systems

Product Description : maximum sound control across a broad frequency range

QuietRock 545 is a multi-layer, specialty panel engineered to provide maximum sound control across a broad range of frequencies. QuietRock 545 is ideal for commercial theaters, studios, performance spaces, and music rooms where low-frequency mitigation is critical.

The panels are UL Certified for use on several fire-resistance rated assemblies and install and finish like other paper faced gypsum board but require a saw to cut. Extra care must be taken due to its weight.
