You could, but if you take it out of the plastic it will be uncompressed which is a good thing. If you don't want to go through all of that then keep it wrapped up. The positive thing about the plastic is it will reflect some of the upper frequencies which will keep some life in the room.
Thanks for the reply , so this wool will be ok to use. I tried to build superchunks before they came out well but i cant really make them again, money is a factor
My room is 12ft 4 in length and 10ft 4 width, 7ft 5 high
i was going to put the rolls in all 4 corners of the room and then buy some acoustic foam for first reflection points or make absorbers which are a little less expensive to make.
Does this sound like a good idea , i really wanted to by some some gik products but will need to save some money
thats one of the reasons i didn't want to take the foam out of the plastic as it will be a lot easier to get out of the room and swap with the good gik stuff!!
I just hope while im saving this knauf wool will help .
