Has anyone heard of Gold Bond SoundBreak Gypsum Board? My builder says the sheetrockers he uses use this in all of the theater rooms they do for personal residences. I had planned on using Green Glue and double sided sheetrock in my 24x16 foot theater room in a house that is being constructed. Sheetrock is to begin next week. Wanted to see if anyone had an opinion.....

Here is your info on it...

I wonder how pricey this stuff is :confused: looks like it would work real well if you doubled it up
