Acoustic Steel Doors & Frames

AMBICO acoustic steel doors and frames combine outstanding sound transmission loss with the appearance of standard hollow metal products. Doors are provided complete with acoustic steel frames, perimeter and bottom seals.

Testing of acoustic door/frame assemblies by independent laboratories complies with the most up-to-date standards on the continent. Fire labelled products have been tested in accordance with NFPA-80 and are certified by Underwriters Laboratories and Warnock Hersey International. Fire labelled products may be supplied in singles or in pairs.

Soundproof steel doors are available 1 3/4″ thick from STC 33 to STC 53. Soundproof doors are available at greater thicknesses from STC 54 to STC 64.

Assemblies have been designed to accept readily available heavy weight builders hardware. Soundproof steel doors are available with acoustic glazing that is factory pre-installed. Radio frequency shielding is also available for acoustic resistant doors upon request to reduce the amount of radio-frequency and/or electromagnetic energy across an opening. Additionally, bullet resistance is available in combination with acoustic resistant openings for heightened security applications.

Our SCIF compliant acoustic door and frame assemblies are manufactured for your security related needs in compliance with DCID 6/9.

What is an STC rating?
STC stands for “sound transmission class”. It represents a method of measuring sound transmission loss through a barrier ie. a door or a wall. The higher the STC rating the better the sound deadening property of the door. AMBICO provides 1 3/4″ thick doors from STC 33 to STC 53. Doors up to 6″ in overall thickness provide a rating of STC 56. Let us help you select an acoustic product that will meet your project requirements.

Are acoustic steel doors supplied with seals and door hardware?
Perimeter seals, bottom seals and thresholds are always supplied as they are integral to the sound deadening properties of the door/frame assembly. Heavy weight butt hinges and latching devices are readily available from local hardware distributors. However, our new STC-53 door/frame assembly is supplied with cam-lift type hinges. When sliding acoustic doors are supplied, all door seals and hardware including perimeter and bottom seals, door tracks and hangers are supplied. Electric operators should be considered when door panels weigh in excess of 350 lbs.

Can acoustic steel doors be provided with glass lites?
AMBICO has tested glazed acoustic doors that have achieved STC 52. Glazing material must be factory pre-installed.

Are acoustic borrowed lites available?
AMBICO manufactures acoustic borrowed lites that achieve STC 55. Individual glass sized cannot exceed thirty two square feet. Acoustic glass is factory supplied and pre-installed.
