Whether you spend your days in a large office in a major city center or someplace more suburban, you’re subjected to a cacophony of loud sounds everywhere you go. Most of us are accustomed to routine noises and learn to tune them out, and we wear hearing protection while using power tools or operating heavy equipment. But we don’t always realize just how much of an auditory onslaught we face each day, and it’s time to level the playing field! National Custom Hollow Metal is proud to offer custom-built Sound Transmission Control (STC) doors, and we can ship them on your schedule!
