Fiberglass insulation service temp limits?

[sberry]

It worked with no negative affects the first several times I did it.


My guess, flames were 10 ft tall.


The smoker was pretty well engulfed on all sides.

I was using 2 layers of foil backed insulation (foil on both sides). I pulled the flaming material away from the smoker with a rake. There was
not much structure left to the fiberglass. It was no longer batts, just a bunch of small charred pieces.

Did it get oil soaked? Glass wouldn't bother me in a smoker.

It seems the FB insul is more than suitable with the only question being the additive binder.

And even then, should be ok for a electric smoker cabinet temps.

Not proposing it for a ceramic kiln. Marc

Leafless - I really don't think the fiberglass itself was burning, it does not support flame, worst case, melts into glass..

I think I would use vermiculite.
