Insulating Blanket - Forno Bravo Forum: The Wood-Fired Oven Community



Photo Galleries are back! Instructions below.

Dear forum users,
Thank you for your patience with the Photo galleries. We've got your galleries online!
We have finished writing a custom script to migrate the PhotoPlog to vBulletin5’s albums.

Unfortunately V-Bulletin killed the "Photoplogs" in their software upgrade which was unforeseen and we're the first development group to have written a script for getting the galleries back... that said, it took some time to reverse engineer the code and get the albums to move over seamlessly!

Forum users will be able to access their “PhotoPlog” images through their user profile page by clicking on the “Media” tab.
They will also be able to browse other albums by going to the albums page. (On the forum site, there is a link in the black bar beside “Forums” to the albums.)

In order for users to create an album please follow the steps below.
1) Go to user profile page and click “Media”
2) Click Add Photos
3) Enter Photo Gallery Title in the first field
4) Click Upload or Select from Photo Album to add photos
5) Click Post
6) Once posted, the album will be created as a “Topic” on the albums page for the public to see. The topic title will be the “Photo Gallery Title” they created before uploading their photos.

To create this migration path we used vBulletin5’s default album structure. Unfortunately, it won’t work like the “PhotoPlog” but is an album/gallery component on the forum now.

  • Insulating Blanket

    I am posting this in both places -- here and fornobravo/forum, where
    we will make it sticky.

    Using a ceramic insulating blanket is a good idea, for both brick
    ovens and refractory ovens, because they are efficient, don't use a
    lot of space, and keep loose insulation from ever getting into your
    oven. And they aren't that expensive. Would folks agree with that?
    Unless budget is a serious issue, you should consider using it. (We
    include a large 6#, 1" blanket as part of our refractory ovens.)

    If you are looking for a place to buy a ceramic insulating blanket,
    contact randy.muchow@thermalproductsco.com. They are in Atlanta, and
    ship UPS. Tell them to give you the price for Forno Bravo customers.

    If you find a better source, or a good regional source, let us know.

      hi james,

      o.k., i am sold on using a insulating blanket, but how much
      pumice/vermiculate insulation can we save that way ?(what would be the
      ratio, e.g 1inch insulation blanket equals 3 inches of vermiculate as
      an example???)
      i really would like to have a super insulated oven, yet like to get
      down in thickness..., since i also like to have as much space on the
      side of the dome for putting things down while using the oven.

        The rule of thumb is 1" blanket and 4" vermiculite. I had an insulation engineer run a test, and conclude that the blanket replaces 2" of loose vermiculite. We had them run a simulation where they added 1" of insulfrax, and reduced 1" of vermiculite. 1":4", 2":3", etc. over a 24 hour 1000F exposure. The outer face tested consistently dropped by adding 1" more insulfrax and 1" less vermiculite.

        1" Insulfrax Blanket 6#, 4" Vermiculite 1000F** 172F

        2" Insulfrax Blanket 6#, 3" Vermiculite 1000F** 161F

        3" Insulfrax Blanket 6#, 2" Vermiculite 1000F** 151F

        4" Insulfrax Blanket 6#, 1" Vermiculite 1000F** 142F

        5" Insulfrax Blanket 6# ******* 1000F** 135F

        Thinking about it, I should ask him to add 1# insulfrax, and drop 3" of vermiculite and re-run the test. I would note that after 24 hours of 1000F, (which you will not approach), the outer face is barely warm.

        I agree that you want the oven well-insulated, but think that you have some wiggle room. My oven here has 1" of low-tech blanket insulation (I don't even know the name of it, but it can't be close to Insulfrax in efficiency), and 2-3" of vermiculite, and I have never felt heat in my stucco walls. This is an extreme example -- I did it intentionally to see how it would work, and I think we can take a small lesson from the experiment.

        Long answer to a short question -- but some interesting background info.
