QuietRock EZ-SNAP is the first high-performance sound reducing gypsum panel that easily scores and snaps, like standard gypsum panels. The patented EZ-SNAP technology delivers outstanding STC ratings with no paper or metal in the center of the panel. QuietRock EZ-SNAP delivers high acoustic performance with improved workability to speed up installation time.


  • High STC performance ratings

  • Patented EZ-SNAP technology allows for easy score, snap, hang and finish like standard gypsum wallboard

  • Easier to snap than other sound damping gypsum panel brands

  • Outperforms other sound attenuation methods, including multi-layered gypsum panels, resilient channel and soundboard

  • High reliability: unlike resilient channel, cannot be easily short circuited

  • 1 hour fire rated, Type X - listed in more than 90 UL & ULC fire resistant assemblies

  • Abrasion resistant paper

  • Less materials installed saves time, labor, and valuable floor space
