THX Ltd and Quiet Solution, LLC, has announced the availability of the first THX Certified soundproofing wall and ceiling panels, QuietRock™ QR-545. By meeting the THX specifications for sound isolation and achieving the coveted THX certification, the QR-545 promises to deliver the professional installer/dealer community with the ultimate sound isolation solution for demanding home theater and studio designs. Drawing from more than 20 years of experience designing and certifying cinemas, professional post-production studios and CE products, THX engineers found that the QR-545 is one of the industry’s highest performing sound isolation solutions, as measured by Sound Transmission Class (STC) standards.

Quiet Solution manufactures the THX Certified QR-545 panels using the company’s patent-pending CPG (Ceramic-Polymer-Gypsum) composite technology. In addition to being tested by technicians at THX, the 1-3/8″ panels were tested by globally recognized labs at the National Research Council of Canada (NRC), which showed the industry’s highest ratings, approaching STC 80, for QuietRock QR-545. This level of acoustic isolation performance is unprecedented, exceeding other techniques by 20 decibels or more. Low frequency performance exceeds 50dB in the highest-rated assemblies. This performance is achieved in a drywall-like panel that hangs and finishes just like standard drywall.
The patent-pending CPG composite technology in QuietRock QR-545 uses advanced viscoelastic polymers, ceramics and gypsum in a constrained 11-layer fabrication. The standard size 4′ x 8′ panels are manufactured by Quiet Solution at its Silicon Valley factory and will be available from more than 250 CEDIA and building material dealers nationwide beginning in October.
