Sound insulation for home theater room
 

I'm finishing my basement and plan to have a room for home theater. I want to put some form of sound insulation in the interior walls and am considering Owens Corning QuietZone. Does anybody have any experience with this product? Does it work or are there better alternatives?

I have done alot of office remodel work and when we were sound insulating a room we would use rock wool insulation, then on one side of the wall we put sound strips. they were a light gauge metalthat attached to the studs horizontaly then the drywall attached to them. the sound stripping was bent like a Z kind of. it ends up keeping the drywall off the studs.It seemed to work

I read on another thread about a product called 'safe & sound' from Roxul, only problem appears to be availability in US. I live close enough to Canada and its available in Home Depot over there so I might try this. Thanks for the idea about the metal track between the studs and the drywall.

Would adding insulation in the ceiling (of a basement) help dampen sound from traveling into other levels of the house?
