Whether an office building is in the middle of downtown, in the suburbs, or a more secluded location, noise can have adverse effects on employee comfort and health.

Our team at National Custom Hollow Metal understands that employees are more comfortable and productive in a quiet work environment, and we’re ready to manufacture Sound Safe Sound Transmission Control (STC) doors and frames to keep your meeting private and secure!
