Library of Congress Packard Campus

Summary:

The Library of Congress Packard Campus houses the National Audio-Visual Center where properly soundproofed rooms are critical to their work. The preservation and restoration processes that take place in these rooms require sonic isolation. Acoustical Solutions was retained to perform routine renovation work on the IAC Acoustics Noise-Lock® doors, as well as add additional functionality to their door closer assemblies.

Application Introduction:

The campus is set on a beautiful 45-acre campus with stunning architectural design and landscaping. The National Audio-Video Visual Conservation Center at the  Library of Congress Packard Campus is a state-of-the-art facility. This is where the Library of Congress acquires, preserves and provides access to the world’s largest and most comprehensive collection of media. It contains a plethora of films, television programs, radio broadcasts and sound recordings.

The physical description of the Campus is impressive. It encompasses 415,000 square feet. Some sections hold more than 90 miles of shelving for storage. Currently, thirty-five climate-controlled vaults house sound recordings, safety films and videotapes. There are also 124 special vaults for protecting flammable nitrate films.

Treatment Provided:

Each preservation suite utilizes high performance acoustic material finishes. Double wall construction and high-performance IAC Acoustics Noise-Lock® Door assemblies provide for a high level of sound isolation. Each suite has two IAC Acoustic STC 52 full glass acoustic doors in a tandem configuration. This means that the whole assembly achieves a Noise Isolation Class (NIC) performance rating of 70. These doors are part of the original construction of the building in 2007.

Acoustical Solutions arrived to perform routine renovation work on the IAC Acoustics Noise-Lock® Doors. This included adding additional functionality to the door closer assemblies. It is important to have maintenance and improvements performed on these doors by factory qualified technicians. This ensures the acoustic integrity of the door is remains intact.

Results:

The IAC Noise-Lock® door assemblies now function with optimum acoustic isolation. The upgrades allow the doors to hold-open without the use of a  potentially bottom-seal damaging doorstop.
