1. If forno bravo sells isofrax ceramic blanket, someone must think its better than kaowool ceramic blanket. Is there much cost differential between the two? Is there much performance differential?


Isofrax 1260°C Blanket is applied as high temperature insulation in the metal, petrochemical / power, ceramic & glass production industries. Isofrax has a temperature rating for use up to 1260°C (2300°F), but the blanket can withstand short-term excursions to higher temperatures - with moderate shrinkage.

Kaowool Blanket 8 LB 2300oF maximum temperature rating.


Isofrax - 50 sq feet, 1" thick - $150.00
Kaowool - 100 sq feet, 1/2" thick - $289.00

2.How about the non-ceramic fiber blanket that is rated to some extremely high temp? I do know that from the e-bay seller, that sells kaowool and the non-ceramic blankets, that the non ceramic is about half the cost? Could someone comment on the non ceramic. ("gee, Tom, you shouldn't have used that non-ceramic blanket, that's why your oven burned down" - hate to hear that later)

Superwool 607 Blanket - 4 LB Density - 1 Roll/Carton (50 SF) Size 300" x 24" x 1" 2012oF maximum temperature rating.

3. how about the insulfrax or kaowool alone, just extra layers.- So, we know what a roll costs,what I don't know is how many rolls do I order to get three layers- 3 rolls? is 3 layers enough? assuming I am not going to use vermiculite. This also means that I will use super isol under the oven, not a layer of vermiculite and cement.

Not sure about the number of rolls.

4. why do you have to cover the insulfrax with the anything at all? Specifically, that mud layer.

If you put enough on, then I suppose you wouldn't need vermiculite or "mud". But it does need protection from the environment. I assume you read James study of vermiculite vs ceramic blankets.
