Large acoustical sliding doors are sometime called “Stage Doors” or “Elephant Doors”.
These are used when a swinging hinged door is not practical because of its size, but the sound needs to be controlled.
We have sold these systems all over the world and continue to do regular quoting.
It has become apparent that there are limited sources for these systems.
the vast majority are electrically operated due to their size.
The most common sizes run around 18′ x 20′ or higher.
Our Sound Transmission Class (STC) is around 53, which is excellent performance on this job.
Being located in Southern California, the movie capitol of the world, we were a natural to supply the studios with what the industry calls “Elephant Doors”.
To date, we have supplied acoustical sliding doors to all the major studios, including Disney Studios, Warner Brothers, Culver Studios, and Manhattan Studios.
One of the reasons for our world wide success with acoustical sliding doors is how the operator and door panels are engineered to work as an integrated system.
The electric operator drives a roller chain that is concealed in the track, so no visible chain or cable is exposed.
Our panels are shipped in 4 to 5 foot widths so they are easier to handle and install at the site.
Each panel has it’s own trolley and when they are all hung they are bolted together to operate as a single element.
The larger the sliding door, the better for us.
30′ to 40′ high is not out of our scope of work.
We also provide constant pressure key switches, relays, safety edges, or any other control required.
The sounds test we have preformed at the job site have exceeded our expectations and in some cases, tested higher than in the lab.
Years ago, sound stages used doors made up of 8″ of concrete and 4″ of instaquilt.
These were extremely heavy and if a problem occurred, even a forklift would not move the door.
Our style test better acoustically than concrete doors did and if there is a power failure, then can be manually operated with little effort.
We often supply acoustical swinging doors with frames, hinges, and gaskets to complete a sound door requirement for our customers.
The sound rating we achieve is 53 STC with a 1 3/4″ door panel and frame.
We have also provided curved or radius hardware in both manual and electrical operation.
We have come to be known as the company that can do anything that slides.
