Can a Wood Burning Stove use a stovepipe made of copper for a chimney?

Question

Planning to install woodburning stove one day. The plan includes exposed stovepipe running up through a loft space, through attic, and out to roof chimney. I know the stovepipe comes in black and stainless steel, but I'd rather the look of copper. The house is made of Cedar with Copper Cupula. The look matters.

Answer 1

Flue fires and the lack of structural integrity of copper under this kind of heat point to no.

A custom job where you have steel stovepipe copper plated will be your solution, copper discolors under heat and picks up fingerprints so those conditions will need to be assessed.

Answer 2

You need to use a listed insulating stovepipe anytime combustible construction is penetrated. These pipes are also listed to be enclosed by construction. Thus it seems acceptable to me to install the listed stovepipe and enclose it inside a decorative copper tube.

For good measure, you should probably have some provision for venting the resulting annular space at the top and bottom of the copper tube.
