Steve Sells Posted April 9, 2009 Share Posted April 9, 2009 but that ;link says rated for 1832F? That is a little low for a welding gasser How do I compare this to other products? I dont know what these numbers compare to. yo said it melts at 2100F But being covers by some top coat our gasser may get hotter, but will that insulation "feel" that heat level?

Frosty Posted April 10, 2009 Share Posted April 10, 2009 Steve: It's fire resistant household insulation, not a refractory. 1,800+/- is the working range, 2,100+/- is melting temp. It might be okay as a wrap outside the refractory but pretty much pollution inside a forge. Welding temps in a gasser are usually in the 2,400-2,700f- range. Coating with something like ITC-100 lets us get away with using refractories that don't have quite that working range but won't stretch it enough to make 2,100f rock wool work.

Frosty Posted April 10, 2009 Share Posted April 10, 2009 Now if anybody falls in the bucket, they will burn up..... need a new sticker ! The graphic would have to have someone falling into the bucket head first like the the kid falling into buckets on the labels now only bursting into flames instead. I love it.

MattBower Posted April 10, 2009 Share Posted April 10, 2009 I have considered buying Roxul as backup insulation for a layer of ceramic fiber. It's cheap, so it'd allow you to cut costs compared to using multiple layers of ceramic fiber. But no, it definitely shouldn't be the innermost layer.
