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.
  1. 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.

    Installation

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

    Finishing

    • 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.
