Sound Transmission Classification (STC) numbers have been adopted by acoustical engineers as a measure of resistance of a building element such as a door or wall to the passage of audible sounds. Audible sounds are defined as voice, music, or any other noises not related to impact sound.

STC rated doors are available in all standard panel raise and sticking options and all face colors.

Our doors are tested to obtain the following operable or fixed ratings per ASTM E90 as conducted and certified by either Intertek Testing Services or Architectural Testing.
