Overly's acoustical wood doors have STC ratings from 41 to 50. Wood doors are provided with metal framing systems and are intended for interior use only. Because of our unique manufacturing methods and patent pending designs, Overly acoustical wood doors achieve a higher STC rating and are lighter weight than most comparable doors on the market.  


In keeping with Overly's LEED Initiative, Chain-of-Custody Certification is available for Overly's Wood Acoustic Door products. In addition, all Overly laminate products contain no added urea formaldehyde resins in their manufacture. This includes both Overly's UL fire rated and non-fire rated wood acoustic door systems.
