Noise Lock doors can be custom built for a variety of different applications with STC (Sound Transmission Class) ratings from STC 26 to STC 70. All Noise Lock sound-rated door designs are tested in the IAC NVLAP accredited Aero-Acoustic Laboratory. Of greater importance is consistently high in-field noise reduction attained under actual job conditions. Noise Lock door units ship factory assembled including leaf, time saving split frame, seals, latching hardware and glazing. Noise Lock custom doors are designed to meet your specific functional and dimensional access requirements. Every door is factory assembled and functionally tested for alignment, fit, and ease of operation prior to shipment. This reduces installation costs and virtually eliminates in-field construction errors that can affect performance. All doors are guaranteed on-site performance of the specification and, if necessary, engineers will be dispatched to field-test and troubleshoot the situation.
