Question Ceramic Fiber Board

Has anyone ever used 3"Ceramic Fiber Board for insulation under your cooking floor Instead 2” Ceramic Fiber Board?

I used three 1" layers of InsBlock 19. Others here have used ceramic based boards as well. 1", 2", 3", it's all the same basic idea. I believe insulation is fairly linear (2" is twice as good as 1", etc.).

Fibre board is a lot less dense, but far inferior in structual strength.

You mean the oven floor? I didn't put anything between them. The bricks went straight down on the board.

Yes, one of the advantages of using insulating board is that it's flat. You can put your bricks right down on it, as I did. Mortaring the floor down is not considered a good idea.

Question FBX insulation board

I bought some 2" FBX Insulation Board today from a refractory company. They told me to cut it with a butcher knife

QUESTION IS: How much weight can this material support? Should I use it for the floor bricks only and NOT the first chain?

A picture would help my understand here....

I apologize if it looks like I'm hyjacking your thread morrishuckeba

Whether you place the first chain on the floor or surrounding the floor, the ceramic board should be underneath the entire floor/dome wall assembly, regardless. The board has tremendous compressive strength.

OK fxpose (George), let me run this by you and see if I really understand, OK?
The board can take the weight of the oven floor AND the dome, yes....?
(It seems very lightweight to do that). Do you put the dome directly on the board, or do you use a layer of sand and fireclay, or perhaps, some home brew?


Thanks for clarification
