Perlite for enclosure - 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.

  • Perlite for enclosure

    I am building the 42" dome oven as per FB plans. I want to have an enclosure that is arched at the top and straight sides. I am considering forming the shape of the enclosure, adding some pencil rod for strength, and filling it with a perlite/concrete mix. After stripping the forms, I plan to finish out the enclosure with Faux brick. The dome would be covered with a minimum of 4" of perlite/concrete mix, but in areas it would be 6-8" thick. Can you have too much perlite/concrete insulation? Could it expand too much when heated and cause problems with the Faux brick finish? Any thoughts, ideas for warnings would be appreciated.

    I don't think you can have to much insulation, but you will be getting some diminishing returns for your efforts. On my build I have a 39" dome with 3-4" of cf insulation, brick walls, and a "hip" roof. I started putting a vermi-crete mixture over the insulation in 1-2" lifts and each lift kept getting stronger with portland and continuing to shape the "hip". When it got where I wanted, about 10," I poured a all concrete top over it in the "hip" shape,overlapping the sidewalls and forming a soffit. I might suggest that if you are going to add "fake" bricks to the sides, why dont you use a cement board to build your walls with..might be easier, you can still go over the top with whatever shape you want,and use the cement board as a guide for your roof. Heres a in the process picture before I put the final concrete top on it. All that vermi-crete takes a while to dry and might be hard to stick fake bricks to. I need more pic's but, wife has camera and is visiting family.... as a after thought, all I am saying is use the cement board for your forms, and then leave it up and put your bricks on it....with some interior framing of course....

      Thank you for your thoughts. Your picture shows almost exactly what I have in mind, but I was considering Faux brick because of the wider selection of colors. My wife has this thing about red brick and the other colors available in real brick. Maybe I can find a real brick she likes , set the enclosure, then fill with perlite/cement mix.

        As a side note, I filled the wall sides with dry vermiculite.....the mixed stuff is only on the top....The more portland that you use , the less insulative it will be....the dome is also sitting on 2" of cf board...no need for forms if you build a brick wall around it all....just leave room for the insulation...I would suggest using the cf blanket and board though...and then, the vermiculite,perlite.....
