What Drywall Is Best for Soundproofing?


Any drywall can provide a measure of soundproofing by adding an extra layer to help reduce noise transfer. But QuietRock, a drywall material specially engineered for soundproofing, offers the more-surefire solution.

STC Ratings

  • STC--for "sound transmission class"--is a numerical rating describing a material's ability to block or absorb noise. The higher the number, the more noise it will block.

Standard drywall vs. QuietRock

  • A standard drywall application has an STC rating of 39, while the top-performing version of QuietRock has an STC rating of 80.


  • QuietRock installs in the same manner as traditional drywall and does not require any special tools or knowledge.


  • QuietRock can be finished and painted just like traditional drywall.

Different models

  • QuietRock is available in nine models, depending on the application, desired STC rating and budget.
