 Re: kaowool vs insulfrax vs non-ceramic blanket vs insulfrax/vermiculite
1. insulfrax from FB store is safer than kaowool but the performance is likely to be similar. Members of this forum have used both insulfrax and 'non-safe' ceramic blanket insulation like kaowool
2. Non-ceramic fiber blanket rated to really high temps? I looked up superwool 607 and it appears to have identical thermal conductivity to kaowool so that should also be ok.
3. Generally 1 roll is 50 sq ft and covers the dome once. If you use insulfrax or kaowool or superwool you'll want 3 inches or you can replace any layer with 2 inches of perlite/vemiculite.
4. You don't have to cover the insulfrax with anything if it is an interior oven that is surrounded by other building materials, but the insulfrax will not perform well if wet so for exterior ovens you need an enclosure.
