Our Answer:

This product is actually designed for insulating flexible fireplace liners, however there would not be an issue with using it to insulate a furnace flue. The b-vent pipe that is typically used to vent a furnace is thicker than a liner, but can sometimes be susceptible to the issue you are having. Insulating it with this product should solve the problem by keep the flue gases warmer.

In Response to Question:

I have a gas furnace which has a 6 inch stove pipe that runs through the attic, there appears to be some heat loss out of this pipe because I get some ice damns in the winter unless I keep the roof clear of snow. Can this material be wrapped around the stove pipe to help prevent some of the heat escaping into the attic? Are there any fire hazards from doing this?
