Re- Insulating my OWB
« on: July 20, 2018, 09:37:43 AM »
I have been painting my Shaver OWB with "Rust Seal" and then plan to put new insulation on to replace the old stuff.  I am wondering if there is an insulating board I could use on the top, that would be better than the Batt Insulation?

Perhaps an insulating board and then Fiberglass  insulation to lay on top of it.  Does anyone have any ideas?

I used some of that foil wrap [for radiant heat] on the one side last year to cover up the rolled fiberglass insulation.

Thanks in advance for your help, I appreciate it

I would think something like this would work good https://www.menards.com/main/building-materials/insulation/foam-board-insulation/johns-manville-foil-faced-polyiso-foam-insulation-3-4-x-4-x-8-r-4-4/w-n5075/p-1444438921381.htm

You will have to keep a gap around the chimney though. The Chimney on a shaver will be way too hot for anything other than fiberglass.

If I was doing it, I would probably wrap some 1" rope seal around the base of the chimney and then cut the insulation board to fit against that.
