Superwool or Non RCF Ceramic Fiber Blanker is made to insulate your wood fired brick oven. We recommend a minimum of 3" or 3 layers of 1" blanket insulation.
For superior insulation, you add add extra blanket insulation to the dome of your wood fired oven. One roll of 1" thick x 24" wide x 25' long blanket insulation will provide an extra 1" to 2" of insulation to the dome of your oven.
We use the Superwool Non-RCF type of Ceramic Fiber Blanket.
