Deep Sea Sound
I used Roxul Rockboard 60 for wall treatments but OC703 is great too. And I used the Roxul Safe & Sound that you can get from Lowes for the ceiling treatments. I wouldn't use the Safe & Sound in wall treatments as they aren't rigid and could sag.So what does everyone recommend I use for the insulation? OC 703 or other?
I used a bread knife to cut the insulation and that worked well.
Regarding size, many recommend leaving an inch between the insulation and the wall so you might build the frame 3" deep and put the insulation near the front to leave the 1" near the wall.
