I’m going to remove the wall board ceiling in my HT in order to plug gaps the builder left in the sheathing at the outside wall at the ceiling joists of the room. This will require 16” x 12” wood planks or plugs to fill the open gaps (bad air leak). I must insulate this section of wall while I’m at it. I’m thinking of spray in place tripolymer closed cell foam to insulate the outside wall and the ends of the joists. I’m thinking of going ahead and spraying the whole ceiling and outside wall. The vendors of this stuff claim it will stiffen the floor (wall) and “deaden” sound passage. Furthermore they say it will reduce room resonances within the home theater (less wall vibration).
My question:
Does anyone have any experience with this material for acoustic performance or sound deadening? I’m thinking that it will greatly stiffen the ceiling and thus the floor of the rooms above the HT, while it effectively seals the gaps the stupid builder left in the sheathing. Thus I accomplish two things at once. Well insulate and seal the outside wall and joist header. And sound deaden the ceiling.
The Home Theater is about 25 ft. x 33 ft and above it is a den, and kitchen. The den is hardwood floors and the kitchen is tile.
When I play, say, “Master and Commander, the Far Side of the World” on the blue ray player the cannons and other noises get through to the rooms above and one can feel the floor vibrate.
I have a technical background and can understand such information, does anyone know of a web site(s) where these matters are discussed in detail?
