can ceramic board be cut just for floor size - 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.

  • can ceramic board be cut just for floor size

    I`m ready to go but I need advice on the ceramic board,, I found a supplier near me[ I live in Al.] that has the 2 inch board in 24 by 48 inch size . I can cut this to fit my interior space on a 36inch oven . How ever on all the photos, it shows this also going under the exterior wall of fire bricks. Is this necessary ??? or can I just cut the ceramic board to fit the center floor and run the fire bricks right on the concrete I have a 5.5 inch thick slab poured for a base I guess I was wondering if the fire brick would transfer enough heat to crack the slab .. I doubt that I would have a heat loss .I would appreciate any thoughts on this ..

    You must under-insulate the walls of your oven or any heat you put into them will bleed via conduction directly into the concrete below. You would be wise to extend the floor insulation 1-2" wider than the walls. If you can swing it, go with 4" of insulation. 2" is on the thin side. You won't be sorry.

      Insulation... in your case, ceramic board insulation....is installed first over the structural slab, and the firebrick is set on top of the insulation.

      If you don't have insulation under brick, heat will constantly transfer into the mass it is contacting.

      So, you should also have insulation under the base course of your dome, the same as you need insulation under your floor brick. If you don't want to use ceramic board under your dome courses, use perlite/portand or vericulite/portland at a ratio range of 5-8:1 (perlite/vermiculite - portland)

      Your brick floor can be cut to fit inside the diameter of the dome or you can extend it so the dome is resting on floor brick...doesn't matter which. Either way, there should be insulation under the floor brick.

        Thanks for the info . I think I will buy a 1inch 24 by 48 also and cut it so it will go under the 1st course of fire brick. I will of course double it up for the suggested 2 inchs .. can always use the xtra under the landing I guess . Looking forward to playing with the dome shape . Did a fireplace and a smoker this will be a new challenge.. Thanks again for reply..

          Left over board can also be used for door insulation.

            Where can I find ceramic fibre board?

            Does anyone know a distributor for ceramic fibre board? Or even enough for a 36 in oven?
