Can I use a radiant barrier -or- floor underlayment as a sound barrier on walls?
 
I'm on a time crunch and decided at the last minute of course that I want some sort of sound barrier for my home theater room. I have a radiant barrier on the outside of my 2x4 studs already can I add a radiant barrier inside over the studs than sheetrock over it? I am in a warm southern climate so I want to keep the heat OUT of my house.

I prefer to not use 2 layers of sheetrock.

This is the product I was thinking about these 2 products --- any advice on this please? Thanks

You will create a vapor trap with that and it is never advisable to have a vapor barrier on the cold wall in the warm/moist South.

"You don't always get what you want" (The Stones). Sheetrock.
