Floating Hearth design - 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!

    I've seen a design where the rebar for the hearth just sits on the blocks for the stand and the cement stand is poured into a frame that is inside of the blocks for the stand. The insulation layer is poured over top of it and the oven built on that. This keeps the oven completely seperate but supported by the stand. Is there any advantage to this system?
    I live in a colder climate, gets darned cold in the winter. With this floating hearth design, it seems like I should have less worries about frost and a shifting slab below... or maybe more? What are your thoughts?
    Also, just for economics, rather than using rebar, I have some old steel posts made of T-Bar, much heavier than rebar. If I were to go with a floating hearth, I'd use these for the support. I would think that over time, the rebar would start to bend....
    My concern is trying to ensure that I don't have a frost issue over time. The slab foundation is 6" plus and heavily reinforced with rebar. The stand will likely be cement block finished with mortar and stucco.
