Heat Shield around Standard Black Pipe

Heat Shield around Standard Black Pipe

PostBy: JiminBucks On: Wed Oct 31, 2007 11:14 am

I what to protect a 2x4 exposed wall stud thats about a foot away from my exit pipe near the stove exit. I placed a piece of metal in between to act as a heat shield, half way. I don't like how hot this metal shield gets. I what to wrap the first foot or so of my black pipe in something to help insulate it better. Any recomandations?

Wrap it with Kaowool, the outside will be about room temperature then. I did mine that way for a few years. You should be able to get some at the local plumbing supply.

my exahust pipe is really close (less than 6"?) to the ceiling joist in the basement, I just put some metal with about 1" air gap between the metal and wood over the pipe, teh wood gets warm, but not too bad or even close to combustion temps.....yes, the metal gets warm, but it dissapates quickly.

I am concerned that wood will dry out to a point where just the heat near the stove from the exhaust pipe might start the stud on fire. I like the idea of wrapping the first several feet of the black pipe in the Kaowool stuff, which should also help with the draft? Jim

That is true, anything to deflect or minimize the heat should help keep it cooler. Not sure what the flashpoint of wood is, but hopefully your pipe doesn't get that hot on the outside.

Insulating probably won't help your draft much, if at all. The draft is normally dependant on the outside temp and the height of your chimney. The colder it is outside, the faster the heat can rise, causing more draft.

I've had the same situation for about 23 yrs. I put up wonder board ( fire retardent concrete ) sheets. Been working out just dandy all these years.

Insulating the stovepipe will increase the draft slightly as stovepipe loses a lot of heat. Wood subjected to years of high temperatures can reduce its flashpoint down to about 200-220*F in some cases.
