I want to build a "Room in a room" for my home theater, but the Ceiling spans call for 2 x 8's at a minimum. I am hoping that someone makes a 2x8 I-joist as they will be MUCH lighter and easier to work with. I don't have the ceiling (original) height to go much more than 2x8.
I know I could either hang a ceiling, or use the isolation clips, having done that once I know I don't get the isolation I want... To keep movies like Terminator-2 in the sound room and out of the living room above, I really need to totally isolate the ceiling and floor above.
I can use 2x8x16's, but they are heavy and not always as straight as I would like. A shallow I-joist alternative is what I really want.
Hope someone can help....
