I haVE a woodstove in my cabin that Im putting a ceiling in. Im using osb for most of the ceiling and want to know what I should use around the pipe. Is there something that I can put around it or a different kind of board?

The code over a boiler is 5/8 sheetrock here with fireproof caulking. I don't know if it would be the same for a wood stove.

Check with your local Building department. Here are some general guilds:

So I can use a sheet of sheetrock with caulking to put the stovepipe through? This is only a cabin so it doesnt have to be pretty.

I wouldn't use drywall. I would use durock.

I agree with Coops, durock is positively fireproof & the flue pipe from a wood stove will at times conduct quite a bit of heat. When it comes to fire, better safe than sorry.

I read that durock is a pain to cut. What should I use to cut the hole out for the pipe? What about hardibacker?

Any more ideas? How do you cut cement board?

Cut it with a jigsaw, but kiss the blade before you use it, as it will be useless. I would search for a transition box that allows the pipe to poke through, but gives appropriate clearances on all sides. I would not use sheetrock, mainly because the paper on both sides will burn. CBU is not structural, and may not hold up to sagging.

Use Tin Ceilings and Accessories (http://www.americantinceilings.com/?source=adwords&campaign=2353974&adgroup=200973680&keyword=17111180&wcw=google) over the stove and leave an appropriate gap in the OSB, maybe a couple of feet each side. Use double wall high temperature pipe. Let the experts weigh in though my idea might not be good.
