heat ducts rarely get above 80 degrees. i went to lowes just awhile ago and they have two sizes of the bubble wrap 16 and 24 wide looks very interesting. don't know yet what i will get. i lke the water heater wrap for the cloth backing seems like it would stick better but then you have the possibility of water soaking if use on the floor up front. may have to vary the material per location. bought quick fix, sames as quick roof have not found the quick roof brand yet or peel and seal. different products different areas. ron
