silver foil - insulation layer - 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.

  • silver foil - insulation layer

    hi all

    About to start the insulation on my dome....after a few running repairs this morning

    Is it best to put silver foil on before the blanket and then the vermiculite outer layer


    blanket - silver foil - vermiculite..


    silver foil - blanket - silver foil - vermiculite...

    also the vermiculite outer mix is 5 -1 cement is it ok to add a little sand to the mix

    With silver this morning at $13.75 an ounce, I'd skip the silver foil. In fact, I'd skip any foil whatever. The most common, aluminum, will be corroded instantly by the portland cement. It really doesn't have any function.

      Hey Ross,

      The foil really doesn't add any value to the system with the blanket insulation. And the Portland does corrode the foil in short order.

      And the sand in the vermiculite mix will not add any value.. the idea is to get as much 'insulation' as possible, and that comes from the vermiculite. You use the Portland (cement) to hold the vermiculite together. The less Portland you use the better the insulation value; there is one guy in this forum who was getting as much as a 12:1 mix. As some point you need the Portland to provide the strength to keep the whole thing together and you can't go wrong with the 5:1 mix.

        Don't add sand the the vermiculite cement mix. The idea is to just coat the vermiculite with cement as loose as you can. The mix creates tiny pockets of air- those pockets insulate (think of a double pane window, thin layer of air in between the glass). If you add sand you fill in the air pockets and lose insulation.
