Sound Proof Sliding Doors | Fire Rated Acoustic Elephant Doors

Sound Proof Horizontal Sliding Doors


Horizontal Sliding Doors are space saving, unlike swing doors, when in the open position they do not obstruct the opening and require no threshold, leaving the floor space clear without tracks. The CDL® Acoustic Horizontal Sliding Door is available up to STC56 in a single leaf and STC70 in combination. Designed for high performance, reliability and longevity, the CDL® Acoustic Horizontal Sliding Door is the ideal solution for large openings and has the option to be fire rated up to 2 hours to NFPA252.

Superior to Traditional Elephant Doors

Designed as a complete system by CDL engineers, this high attenuation acoustic door is a product proven with independent laboratory testing and decades of in-field acoustic tests. Unlike “Elephant Doors” CDL's Acoustic Horizontal Sliding Door operates smoothly and quietly without the need for a floor track.

The CDL top hung design results in a smooth and quietly operating acoustic sliding door featuring controlled acceleration and deceleration cycles in opening and closing the door. This acoustic door system uses abundant safety features, such as instant stop wireless safety edge and constant contact control buttons.

An ideal sound attenuating door solution to large openings in markets such as; film, theater, education and industry. The doors are available with acoustic performance and the two-hour fire rating per NFPA 252, thus eliminating the need for additional fire shutters.
