Hearth insulation - 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!

  • Hearth insulation

    Thanks to many of you who have posted on Hearth insulation. I have a Mugnaini Medio 110 oven kit and the Mfg. calls for 6" of sand under a 3" concrete base under the hearth. They say that while the sand acts less as an insulator but more as a heat sink to develop thermal mass and keep the floor hotter longer. Although it does take 20 minutes longer to come to temperature. Any thoughts on this design vs perlite/vermiculite concrete mix?

    It sounds like something counter productive to your needs! You need the thermal mass under your hearth not to be a drain for your heat, the insulation is to keep it (heat) from being sucked out. Unless, I've gotten it wrong?

      Do you have a forest of wood to burn?
      Do you have countless hours to waste stuffing the forest into the oven?
