Temp resistence for insulating the Hearth? - Forno Bravo Forum: The Wood-Fired Oven Community



New Forno Bravo Forum Feature

Forno Bravo Forum Community,

You will notice a new forum at the top of the main page called, "Ask Me Anything". This forum will be used for live one hour "Ask Me Anything" (AMA) sessions hosted by people who are knowledgeable in different areas pertaining to wood fired ovens. How it works:
- Each AMA will have a "sticky" thread where the community can post questions they would like answered during the live session. This will allow everyone to participate even if you can't be online for the live session. These questions will not be answered by the host until the live AMA; if you need an answer quickly, you should post it in the appropriate Forum area for the community to respond.
- Another thread will be posted for the live AMA. Registered users who are logged in during the live session can interact with the host by asking questions and receiving responses.
- The live thread will remain in the AMA forum to view after the session.

To kick off our AMA feature, we have invited author, chef and master bread maker and host of Pizza Quest, Peter Reinhart, to be our first host! Peter will be in the Forum on Monday, February 15th, from 7:00 - 8:00 pm EST. If you are unable to be online during the live session, you can post your questions in the sticky post. Peter will answer those questions during the live session on February 15th. You can view Peter's answers to your questions as well as what happened during the live session in the session thread.

We hope you enjoy this new feature! Please let us know if there is a topic that you'd like to have as an AMA and we'll look for a host!

  • Temp resistence for insulating the Hearth?

    I'm building a brick oven and I've seen insulation online that handles 1200F up to 2300F. I can source some 1200F stuff locally but will need to buy anything higher temp online so just wondering if the 1200F board will work or if I'm better off just getting the higher temperature stuff.

    1200 F should be plenty
    Kindled with zeal and fired with passion.

      Thanks for the reply. Should I go with 2 or 3 inches thick?

        The minimum thickness should be 2'. If you take a look at our residential ovens, most include 1x 2" insulating boards. The Premio2G oven kits include 3' boards but keep in mind these ovens are heavy duty residential ovens for frequent usage or heavy baking. If you go to our library, you'll find the dimensions for our residential ovens and you can use it as as a guideline for your own oven. Again, this is just a recommendation but custom ovens are up to the individual. I hope this is helpful to you.
