Insulation types - 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!

  • Insulation types

    So I'm new to the wonderful world of wood burning pizza ovens, Ive read about ceramic blanket and vermiculite has anyone tried Rock Wool
    Its a mineral wool insulation. It's what we use at work (I build powder coating ovens for a living). I don't know if it would work for this just
    wondering if anyone had given it a shot.

    Ever Forward

    Should work, CFB is rated higher, Mineral wool is a bit denser I think.

      Re: Insulation types

      Did a quick search on this and found bulk "rockwool" for about $45 that is spun from molten rock and used in landscaping and for plantings. Is this the same stuff? Do you think I could use this alone or would I still need to fill the outer cladding with vermiculite as well?

        Do a search in the forum for rockwool. It has been discussed a couple of times. In fact I used rockwool on my oven, although I don't think the landscaping stuff would work. You do need a product that can stand high temps on a regular basis.

          here is the stuff I have at the plant we use it in powder coat oven applications
          but we are usally dealing with oven temps in the 400 f range
          and heater temps around 600f

          Ever Forward

            here is the stuff I have at the plant
            The PDF says it's rated for temps up to 1000f, so you should be ok. I worry about it's rigidity for under oven use: it says it conforms to irregular surfaces.

              use it and if you have room, use lot's of it!

              I think for dome cladding it would work fine, under the hearth, how do you keep it from compressing?
