Recent refrasil sources?

The title speaks for itself.

thanks Eben, I would need smaller quantities for a client. Enough to do a small Stadelman furnace.

He doesn't stock Refrasil, but John Han over at Rubix Composites has a roll of coated fiberglass cloth (it's normally used as welding blanket) in the warehouse that is good up to 1000F. Should be just fine for laying over a furnace top to keep down the silica dust. (Direct quote from John: "If the top of their furnace is getting that hot, they have waaaaay bigger problems than this blanket's temp rating"). Comes in a 60" roll and is sold by the yard.

Hazard Fraud has welding blankets that hold up well in the annealer so I would say safe to use to cover exterior fiber. That is the cheapest source I have found and can be picked up locally.

Why not use pink fiberglass home insulation? I use that as the top layer under a sheet metal skin. It works great

If you have a sheet metal skin, it performs the same function as the refrasil and you no longer need it. Refrasil contains the fiber but it has no insulation value.
