I have finally made all the changes to the room. Thank you all for your suggestions I did most of them. I put rivets in every piece of t-bar and there is enough insolation in the ceiling now to insolate the whole house. I still have a slight ratteling problem but I am not to worried about it as I am moving in October anyway, and get to start from scatch again. My next attempt at a theatre room will be more thought out I am already doing the planning.
