Super Isol vs. vermiculite concrete - 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!

  • Super Isol vs. vermiculite concrete

    The Super Isol insulating board has better compressive strenght than vermiculite concrete and better insulating characteristics as well (see http://www.skamol.com/pdf/1%5Bcalciu...s%5DLetter.pdf and http://www.schundler.com/vermcon.htm), and while it's not cheap it would save a lot of time and would eliminate concerns such as getting both pours done in one day.

    Any actual experience comparing the materials?

    Cost vs. Time Tradeoff

    I think Alan has it right. The Super Isol costs a little more than the cost of the vermiculite and concrete that it replaces (not a lot), but it counter balances that cost with convenience. If you are paying someone to do that part of the job, I think the labor savings probably makes the two alternatives pretty comparable from a cost perspective.

    There are also the intangibles, including the effort of mixing and pouring the vermiculite concrete, two pours in a day, needing a helper, finding vermiculite locally, driving to pick it up, etc.

    The good news is that you get to decide what works for you depending on your own circumstances.

      finishing iso

      So how do you finish the top of it. If this sits on the concrete hearth then it is exposed no? Can you tile over it? Also, do you glue it down or just lay it there.?

        You use the Super Isol just for under oven insulation. You never see it after you have installed the oven. You glue it down, and assemble the oven on top of it. The insulfrax wraps around the oven, and the vermiculite goes around that. Basically, the whole oven chamber and floor are wrapped in insulation.

          Super Isol

          I gotcha! I had picured it replacing the entire layer of vermiculite. Makes perfect sense.
