This stuff is VERY rigid....i could not roll it up if i tried....probably would take alot to fold it in half....its pretty damn dense.
After doing some recording and mixing today, i notice the difference for sure....Everything is just more noticable.....And walking and talking around my house i have the huge echo....and as soon as you walk in this room its DEAD....which is very weird feeling haha. My wife walked in and was talking and immediately stopped cause it felt weird she said hahaha.
