Yes I have a Family Room that was built on a cement slab and underneath every thing there is a crawl space about 2 foot deep. I can only go in there about 2 foot because of the Heat Runs are running and their is no way I can crawl under or over them.There is no insulation on the Joists or outer walls. Does anybody have any Ideas? Any and all Ideas will,be helpful. Thank you in advance.
