Hi,
my gas furnace sits in the laundry room in the basement and there is a lot of heat that comes off the pipe the sends the hot air up into the house. I went to HD and asked about wrapping some form of insulation around the pipe. I was first told to use batting wrapped in plastic. Thought this was not going to work given the amount of heat that comes off the pipe. Of course I wasted money on that after seeing the batting turn brown and fall off the pipe (had it taped on with heat resistent tape). Went back and someone else provided me with a foil wrap that sandwiches bubble wrap - I think it had an R rating of 4. Went on easily but as soon as the furnace kicked on, the bubble wrap shrunk and is now just a piece of foil wrapped around the piping. Im starting to think this isnt meant to be. I have only found stuff online that talks about insulating the heating ducts but nothing that provides any info on insulating the actual pipe that comes out of the top of the furnace. Is there such a thing?
Thanks.
