Well the room im using for my home theater is faily large. It is sort of a Z shape and the section I am using for the viewing area is probably about 15 feet wide and 30 feet long. Is there a cheap insulation solution at home depot that most people use?
I found something that looks pretty interesting to me. If you go to
www.mcmaster.com and then search for product 55075T21. When it finds it on the left, click on "Catalog page" and scroll down to see it. They're 36X36 sheets of fiberglass sound absorbing sheets. They have an NRC of .60 and only cost 3.26 per sheet. Does this sound promising? Matt
