Need advice from some of the experienced builders on the forum please.
The stand and hearth for my WFO is built and their combined height is 33 inches from the floor. I am assembling as Casa2G oven and would like the oven brick floor to be approximately 43 inches from the ground. So I have 10 inches of height to make up. 4 of these inches will come from FB board and floor tiles themselves (2+2 respectively).
This means, I have to add ~6 inches of suitable material between the hearth and the FB insulation board. Do note that oven dome will be encased in an enclosure, so I only need to add enough material to raise the oven and the front of the stand where granite slab will come. Everything else will be hidden inside the enclosure.
I could come up with the following options:
1. Pour another six inches of concrete on top of current hearth. Seems like a lot of back breaking work and would love to avoid it.
2. Pour 6 inches of vermicrete instead to reduce effort and increase floor insulation. This adds a lot of time to the build process as curing takes a while. Time is an issue for me for several reasons.
3. Dry stack two layers of red bricks on the hearth to build a 6.25 inch platform that the FB insulation board can sit on. First layer of bricks sits on its side and the second layer of bricks is flat (4+2.25 inches). This seems easiest and relatively cheap, but not sure if dry stacking two layers in this manner will be stable. Would weight of oven hold all the layers together securely?
4. Dry stack single layer of red bricks on their side to build a 4 inch platform that the FB insulation board can sit on. Even easier than #3, but I am comprising on the final height a little bit.
Any other creative solutions the good folks of this community might suggest? I would happily take option #3 if dry stacking two layers is not an issue. I could use either clay bricks of concrete bricks as cost effective and fast solutions.
Thanks in advance
