After reading through all the posts about Roxul and researching it on the company's website, I just insulated above the damper plate of my fireplace with Roxul. After I was finished packing the chimney with two layers of Roxul I started a small fire in my stove just to see what reaction the heat may have on the insulation. It was fine. I was happy.
Then I took a small piece of the insulation and put it in the stove on top of a split that had a small flame curling up on it. I was very concerned when, after a few seconds of being exposed to the flame, the insulation caught fire, turned white and virtually disappeared.
I read that others had used a torch on Roxul with no effect. Needless to say I was glued to my stove for the rest of the day inspecting any signs of heat damage.
Has anyone else had this experience? There has been no signs of heat stress on the insulation but the fact that the insulation burned like that in a cold fire has me very concerned.
Thanks in advance for your help!
For background purposes I just installed an old Vermont Castings Resolute on the hearth of my fireplace and used single walled 6" pipe through the entire chimney and capped it at the top.
