Hey guys. Sorry for posting such a simple question, but I'm planning a sound panel build for my bands practice area. How do I figure out how much Guilford's of Maine that I'll need? I'm making 4 corner traps going up to the ceiling and at least 6 - 24" x 48" x 5.5" thick panels for the walls. I'm using Rockwool, and the corner traps will be cut from the 15.25" panels, then doubled, to form my triangles that'll go up to the ceiling. If anyone can help, I'd appreciate it.
