EZ-SNAP Mold Resistant

Made in the USA

QuietRock EZ-SNAP Mold Resistant is an advanced sound damping gypsum panel that offers high acoustic performance for your specific design goals. The mold resistant treatment of the paper and core can contribute to a healthier indoor environment. With EZ-SNAP technology – QuietRock EZ-SNAP Mold Resistant provides easier installation than other acoustical drywall brands.


  • High STC performance with added mold-resistance

  • 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

  • Mold resistant per ASTM D3273 – Ideal for mold sensitive applications
