You never quite realize just how much noise that we manage to filter out as we go through our daily routine. Whether we’re at work, in traffic, having dinner, or just trying to relax at home, we’re constantly bombarded with noise, and don’t realize it until those times when we really need to be able to concentrate in silence. Some people are pretty good at working through just about any racket that they encounter, but we can all agree that a quiet workplace is typically more productive.

National Custom Hollow Metal offers Sound Transmission Control (STC) doors with an STC 51 rating to control excess noise in the workplace. The STC rating is a scale that rates the doors’ abilities to suppress excess noise, and ranges from 20 to 60, which. Doors with an STC rating of 20 can significantly reduce the sounds of normal speech, and doors with a rating of 50 or more can make loud human voices virtually inaudible, and filter out most other common noise pollution in the workplace.

Our STC doors are custom built in any size up to 4’ x 8’, in your choice of stainless or galvanneal 14 or 16 gauge steel. Our STC doors are single or pair entry doors and frames custom built as a complete assembly that’s shipped installation ready. Our STC doors all feature a proprietary acoustic core with state-of-the-art noise suppression technology, and you’ll notice an immediate reduction in overall workplace noise. In addition to controlling general noise pollution, you can also hold confidential meetings in your conference room without worrying about having your proceedings overheard by others.

Like all of our stainless steel doors and frames, our STC door assemblies are built to order, and shipped on your schedule. Quik Ship service is standard with every order, and we also offer expedited shipping options. Most importantly, we stand behind everything that we sell with a 100% satisfaction guarantee. At NCHM, The Difference is Quality!
