Karp is pleased to introduce our newly redesigned STC-64 Acoustical Sound Rated Access Door. It is designed to reduce sound transmission and contain noise associated with mechanical systems and environmental noise. The STC-64 is the perfect door when sound issues occur in high-rise residential buildings, schools, hospitals, and judicial settings. Karp’s redesigned STC access door was tested to exacting standards such as ASTM E1332, E90, and  E413.

The Karp STC-64 Acoustical Access Door is a high-quality, galvanized steel access door fabricated with 2 3/8″ thick acoustical insulation, providing a Sound Transmission Class of 64—the highest in the industry. The 3/8″ by 1/8″ closed cell neoprene gasket additionally contributes to the access door’s noise reduction capability.

Also available in stainless steel. A lockable compression latch is standard. All STC-64 are made to order.
