Acoustical Capabilities

For this reason, STC (Sound Transmission Class) ratings have become a primary consideration when choosing doors for large-scale projects. VT's sound resistant STC doors and jambs are found in every application from airports, healthcare and hospitality facilities, to government and municipal buildings, as well as educational institutions.
