Inquiry (采购产品): soundproof studio I am building a 4'x8'- with7'walls - recording studio in my basement. I have the walls (2x4) up, and had planned to use 2"x4'x8' styrofoam ($9.99/sheet) for the walls and ceiling. Not sure what to use for the door. Rough opening 30"x 82 1/2", thought I might build my own using 2" styrofoam as a core. Question is, have you a better suggestion, what would the cost be to me, and could the products be shipped to my home in Saginaw MI? **** Hidden Message ***** Ken Smith 7250 Spring Lake Trl.
