Insulation behind brick fireplace half wall, very tight? What is best to do?
I gutted my family room and know I need to insulate behind a brick half wall with a fireplace in the middle, the brick is about 5 ft high by 12 with 2x4 construction behind it. It is very tight, I don't think I could get rolled pink in there effectively, i would like to have a vapor barrier with the insulation. I was thinking rolled plastic the best I could behind the brick and fill with afire retardant cellulos Any suggestion?.
