Your client has requested that their new home theater not disturb the rest of their household during viewing. The walls to the theater are designed to achieve an impressive STC performance rating of 65. The entrance door to the theater is a solid core wood door with full perimeter gasketing. Everything should be great, but its not … you’ve got a problem, a BIG PROBLEM. Your client can hear every word coming from the cinema while he’s in his study just a couple of rooms down the hall. What happened?
Many things can determine the overall performance of a theater and doors are a common problem. Many might think that by increasing the walls performance it will overcome any inadequacy of the door. Not true. In fact, you could continue to increase the wall’s STC performance far beyond it’s rating and it would have no effect on the outcome. A standard solid core wood door with perimeter seals has a STC performance rating of 25. As a result, the overall composite wall performance in this example is now only a STC-34. (See Graph #1)That’s the same STC rating as a regular 2×4 stud wall with no insulation. An expensive theater just became even more expensive to fix.
