Hot Wood Storage Ceiling - 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!

  • Hot Wood Storage Ceiling

    I have a 3 1/2 in slab with 3 1/2 perlite topped by 4 1/2 inch firebrick. The firebrick, mostly 4 1/2 X 6 X 18", form the floor.

    The ceiling of my wood storage area, under the oven, gets very hot to the touch after a large party and good fire.

    Could I apply a layer of rigid foam or other appropriate substanceto the ceiling to prolong my oven heat even more? Or am I just wasting time and money?

    The underside of your slab shouldn't be much more than warm after a long firing. I'm thinking residual moisture? Maybe it's gotten wet after construction?

      The 3 1/2 perlite is what should do the job. I would not put any additional insulation under the structural slab for two reasons:
      - It is not likely to contribute much to the heat retention of your oven.
      - You do not want the temperature in your structural slab to exceed 500 F or the re bar within will start to loose strength.

        Derk - I need to ask the question; what is hot? David has a valid point if it's still curing.

        My opinion of insulating under your hearth; it's like putting roofing shingles on the floor to keep things dry. Do you have an option of putting a couple of inches of board under your hearth brick? As Neil mentioned, the insulation you have should do the job. Hopefully it's still curing.
