The average city dweller or suburbanite is bombarded with a cacophony of sounds each day, and we all do our best to tune them out. Sustained exposure to noise levels greater than 70 dB can cause permanent hearing loss, and we’re routinely exposed to noises of over 100 dB near airports, construction sites, and other high-traffic areas. Excessive noise increases our stress levels, and it can also negatively impact workers’ productivity. But our team at National Custom Hollow Metal is here to help, and we can give you a quote for Sound Safe Sound Transmission Control (STC) doors in two hours or less!

Sound Safe doors offer superior noise-reduction capabilities and, like all of our products, are custom-built to your specifications. STC doors are ideal for recording studios, auditoriums, and anywhere you’d like to control ambient noise. Many companies also install STC doors & frames in their conference rooms and boardrooms where confidential information is routinely discussed.

STC ratings measure a door’s noise suppression capabilities and range from 20 to 60. An STC rating of 20 offers average noise suppression, and our STC doors have an STC rating of 51, rendering all but the loudest noises completely inaudible to anyone on the outside. We can manufacture doors in any size up to 4’ x 8′ as a single- or pair-entry, and they’re shipped as a complete, installation-ready assembly. The assembly package includes the door, frame, hinges, gasketing seals, flat thresholds, and your choice of either brush-sweep or retractable auto door bottoms. All you have to do is add your lock.

We offer free Quik Ship service on all orders, with a 3-week lead time for standard galvanneal doors. And if that’s not fast enough, we also offer expedited shipping in 5-10 days for limited quantity orders. Your doors will be finished and cleaned at the factory, and carefully crated for damage-free shipping. Let us know when and where you need your doors shipped, and we’ll take care of the rest. The Difference is Quality at NCHM, and you can always order with confidence because we stand behind all of our custom-built products with a one-year warranty!
