I have a concrete curing blanket available for sale. It is double-walled and has never been used on concrete. I used it to insulate a portable building and it worked great. It does have a couple of small rips in it, but is in otherwise good condition. It would work great to insulate a garage, attic, or basement. It measures 12' x 25'. I'm asking $35 for it. For more information, give Bob a call at (816) 437-4744.
