Using Isulfrax - Forno Bravo Forum: The Wood-Fired Oven Community



I'm Peter Reinhart! Ask Me Anything! Monday, February 15, 2016 7:00-8:00 pm EST

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.

Ask Me Anything New Forum Feature

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.

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!

  • Using Isulfrax

    I've been reading about the benefits of insulfrax, especially in tighter spaces like mine, but have found no info on how to use it.
    1. How do you attach it to the dome?
    2. How do you attach it to another layer of insulfrax?
    3. How do you attach the insulating concrete to insulfrax?
    3. If you were to actually use five layers of insulfrax, can you/how would you
    attach a stucco layer? Too fragile if you banged into without a more solid
    surface undeneath?
    I'm still in the planning stages and am trying to get things settled in my
    thick skull. Thanks.

    I'd also like to know. . .here's my plan:

    I'll wrap the dome in insulfrax (overlap it and cover it well) and hold it down on the dome using duct hanging strap (thin perforated metal strap 1" wide which comes in long rolls, used for hanging HVAC duct from the ceiling). I'm not sure how to anchor the ends of the strap; I may drill holes in the sides of the hearth/floor bricks with a masonry bit and use blue Tapcon screws through the holes at each end. I suspect I'll use maybe 8-10 straps to hold fast all the insulfrax.

    I've seen pix on the FB installation website, and this looks like what they're doing. Bungee cords could work but I don't trust they'll hold up under the heat.
    There is nothing quite so satisfying as drinking a cold beer, while tending a hot fire, in an oven that you built yourself, and making the best pizza that your friends have ever had.

      Thanks Fio. Sounds like we're both in the planning stages. I checked the manufacturers site and didn't find much. They did show anchor-loc. It looks like the insulfrax in layers with an integral mounting system. Wouldn't work for an oven, but it gives one some ideas. The link below is a pdf file containig some info and pictures.


      Has anyone used it yet? If you have, how'd you do it. James, do you have any information regarding it's installation? I'll keep looking.

      I saw a pic of a blanket wrapped in chicken wire. Looks like it would work. Can you then just add the insulating concrete or stucco?

        blanket install pics

        Hey Fio I found some pics from Kiwipete.


        Looks like he has 2 anchor points up front close in to the opening. Chicken wire the whole thing and a strap around the bottom and face holds it all in place. Further down the page shows him applying perlcrete directly to it. I think that answers a lot, but would still like to hear from others.
