Acoustical Capabilities

Noise is one of the single most common complaints at hotels, condos, and other commercial properties. 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 are found in every application from airports, healthcare, and hospitality facilities, to government and municipal buildings, as well as educational institutions.
