Insulating black stovepipe question

[kanelr]

Hi all.
While we have a Vermont Castings unit with triple wall stainless in our house which is great, in the barn is a lesser woodburner with 6" single wall black pipe that runs vertically indoors up to the 20' ceiling and out through a rain cap. Problem is that the smoke cools too soon to get any good draft when its wintery and cold. Does anyone have experience with adding insulation, or sleeving, or mineral wool wraps. etc? the entire pipe is far away from any combustibles
thanks

The right way to do it is with doublewall connector pipe to the roof then insulated chimney through the roof. I can't give you advice on what you are proposing.

What you are proposing is not by the book, but it would help keep the flue gases hotter. Double-wall stove pipe is what is recommended for this application.
