Is my benchtop usable? - 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!

  • Is my benchtop usable?

    Hi All,

    first post

    I need a little advice. i've built the bench top (photos attached). after reading around realised i may not have found the best way to do it.

    basically i have a concrete subbench (standard GP nothing special) with reo mesh. with heat proof concrete holding down the top concrete bench.

    i have a pizza oven kit already that im going to build myself.

    basically, will i have issues with heat destroying the benchtop, and if so can you recommend how i would solve this without redoing the benchtop?

    Cheers in advance, hope someone can help

    You will need to insulate between your oven and concrete bench or the bench will act as a heat sink. This can be done several ways, CaSi board (most thermally effective), Vermiculate or Perlite/Concrete mix roughly 8 to 1 ratio (cheap but requires more thickness), insulating brick (although expensive in your part of the world).

      Thanks Utah!

      What thickness CaSi board do you recommend?

      the Vermi base isnt really an option as i dont want to add too much height if i can avoid it.

      re the bricks, im not even sure what bricks came as the internal floor for my oven.

      Thanks for helping out

        for CalSil Board the minimum recommended thickness is about 1.5 inches. This is the standard thickness from many suppliers. Some of us double up for even more insulation but it's probably not necessary.

          Insulating bricks are very different than bricks that you will use on your floor. They are very light in weight and have good thermal properties for insulation. CaSi is a good way to go, I did a quick google search for refractory materials in Perth and several companies came up. Good luck.
