Sound Retardant Doors
Product Classification: 08348

PP-PRODUCT PRESENTATION

Overly Metal Swinging Doors have STC (Sound Transmission Class) ratings from 43 to 57. Because of our unique manufacturing methods and patented designs, Overly Architectural Acoustic Doors achieve a higher STC and are lighter weight than most comparable doors on the market. Doors are available in single swing and pair configurations. Pairs can have both leaves active or one leaf active and one leaf inactive.

Sizes of Overly Metal Swinging Doors include:

- Personnel size, which is up to 4' x 10' singles and 8' x 10' pairs
- Oversized, which is any opening larger than personnel size in any dimension. These doors require additional thickness to provide necessary structural integrity

A majority of our personnel size doors are available with 3, 1-1/2, and 3/4 hour UL fire labels. Oversized doors are not available with UL fire labels, but a certificate of UL fire-resistant materials and assembly techniques from Overly is available.

In addition, Overly Metal Swinging Doors offer the following features:

- Frame gasketing systems include: Single and Dual Overly H compression seals and Single and Dual Magnetic seals.

- Door bottom sealing systems include: Semi-mortised automatic and Overly Super H compression types.

- Hinges include: Level swing ball bearing type on door with automatic door bottoms and Overly MCL-500 Cam-Lift hinges when Overly Super H door bottom is used.

- Pairs of doors meeting stile astragals include: Surface-mounted compression type; surface-mounted magnetic type; integral compression type; and for pairs with both leaves active, a surface mounted split type.

- Vision lights include: Single glazed clamp-on; dual-glazed flat loose stop.

- Sheet steel materials used for fabrication include: A366 cold rolled; A924 galvannealed with A60 coating; type 304 or 316 stainless with #4 finish.

Full details of each of the above listed features are available. Consult factory.

In addition, Overly offers the following swinging Metal Doors for specialized applications: an STC 46 dual-glazed full light door for applications that require excellent acoustical performance and maximum visibility; a fully tested STC 48 pair of doors that allows both leafs to be active for exit door applications; STC 49 and STC 50 models that utilize single and dual magnetic seals respectively which, when tested, obtain these ratings without the use of a positive latching device.

Additional performance options that can be incorporated into some door models include: airtight, blast/pressure resistant, and UL bullet-resistant requirements. Depending on the individual design criteria, all features may not be available for each Overly Door model. Consult factory with your project’s specific needs to determine availability. To assist in determining hardware compatibility with Overly Acoustical Doors, a hardware information bulletin has been created and is available from the factory.

Typical installations for personnel size doors include: theaters, concert halls, conference rooms, test cells, recording studios, factories, mechanical rooms, and educational classrooms. Typical installations for oversized doors include: large test cells, theater stage doors, mechanical rooms, and convention centers.
