Most seem to be in the 2200-2300 range.. You also need to coat it with some kind of cement or ITC 100 type product or both. You don't want exposed kaowool shedding in your shop at 2200F.
Thanks for the info. My use would not be continuous, just sporadic . Yes, I coat the ceramic wool with a refractory type cement to avoid having the ceramic fibers blowing into my lungs! This will be my 4th propane forge using ceramic wool as an insulator. This particular vendor/ model is new to me so I am just checking. It looks like I can get both boxes for $10.
