could I use these in place of the second floor slab? - 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.

    Ceramic Kiln Fire Brick K-23 IFB

    K-23 straight IFBs (Insulating Fire Brick) 9"x4.5"x2.5"

    I have heard a lot of people complain about insufficient insulation in the floor. I see these insulating firebricks for sale locally. Could I pour the normal 3" slab for the floor, then build the next layer out of these firebricks, before laying down the conducting firebricks for the oven? Skip the vermicrete / FB board and just use IFBs for that entire section?

    Is this a good deal @ $2/piece?

    you could use them, although I think you'd want to maybe lay them on edge. Check the ratings, I think IFB is less effective as an insulator than CF board, so you'll want more than 2.5".

    $2 each is a good price for IFB, but how many of them does it take to make up the same area as a sheet of CF board? That's the price comparison I'd do. Check the prices of CF board at McGill's Warehouse.

      I looked up IFB properties and found thermal conductivity on the order of 0.3 W/mK. Forno Bravo board claims 0.13 W/mK. So yes IFB is slightly less but I think when you get below 1 W/mK it's a great insulator and you're splitting hairs to measure it out to two decimal points. Anyone have a # for 4:1 or 5:1 vermicrete?
