insulating fire brick questions - 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!

  • insulating fire brick questions

    I have the opportunity to purchase the following insulating fire brick for $1 each: BNZ fire brick From searching the forum, it seems like fire brick is considered the insulating equal to vermicrete. When I came across the brick for sale, I was hoping it would be a superior method of insulating the oven. Given the costs of the brick, does vermicrete have an advantage over the insulating fire brick? I haven't priced vermicrete, but I assume the price will be close to that of the brick. Seems like it would be easier to work with the brick for insulating under the floor. At this point, I am also considering insulating the dome and vent with the brick. Any disadvantage to this? Thanks for any opinions.

    At that price, I would so go for it. Usually they are pretty expensive, but those specs (for the lowest density brick) are close to perlcrete/vermecrete.

      Thanks. So, should I double up the thickness or just go with the 2.5" thickness of the brick? I plan to build a 42" Pompeii. Do you think 200 bricks will cover insulating the floor, dome and vent/chimney area? My rough guestimate is that should be plenty unless I need two layers.

        The data sheet did not have sizes.

          Yeah, should have specified. 2.5 x 4.5 x 8 Thanks.

            I would double up on the floor (I wish I had) and use a combination of ceramic blanket and vermicrete on the dome. If you don't want to drop the cash on the blanket, you can always double the thickness of the vermicrete layer on the dome. It might be a pain in the butt to insulate the dome with brick. Just my .03 (I added a penny for experience).
