Alright, my theater is going in a 600 square foot room over the garage. Part of the walls of the theater are the underside of the theater. I'm not that worried about sound going out of the house since I live on a 10 acre lot. If the neighbors can hear the movie, then I am already deaf in the theater and won't be able to hear them complain.
When I was buying all my materials at HD, the pro desk guy said I should use those styrofoam Durovent vents on the underside of the roof decking. It is to allow any heat created from sunlight on the roof to either move up into the attic or down to the vents in the soffits on the bottom edge of the roof. I've put some up and covered it in insulation and compared it to a section without the vents. I can tell it does help by touch, but I did not measure anything like temp difference. I am wondering if I NEED to put a fire stop in there somewhere. I am assuming that I don't have to put firestops in since it is the underside of the roof but I thought I better ask now before I finish it all. The Durovent vents I am adding work better if they can draw cooler air from the soffits and vent the hot air into the attic. A definite plus in Texas summers.
BTW, the rest of the rooms upstairs do not have any of these vents in their walls. The house was built in 1987 if that matters.
