Sound Doors

The high density and solid nature of TruStile doors gives them very good sound reduction characteristics. However, it is ultimately the hardware gasketing and perimeter sealing package that determines the sound rating that a door achieves. The same style of door can achieve very different sound transmission ratings based on the type of sound control hardware that is used. To learn more about controlling sound through door openings visit “Understanding STC Ratings.”

To make ordering STC rated doors from TruStile easier, we have tested our MDF and Wood Doors with hardware packages from Zero International and Pemko. We display these packages as Package A, B and C in the tables below. All of these ratings are for operable single swing doors with the sound control hardware specified in the right hand side of each table.
