Thanks for your response to my question on Clear Vue DC! My anticipated shop is an addition to my house (14 x 28),which is being used for storage at the present but no access to the house itself. It has concrete floor and walls. My question is what to cover the walls to give me the most noise reduction for the buck! The ceiling is a slanted wood joist roof, which I plan to add regular insulation. Any advice for the walls and ceiling would be appreciated!
