Block Wall

What's the minimum distance the slab needs to be outside of the block wall? (I live in Maine)

Thanks

Re: Block Wall

For my 40" oven I'm coming up with a 7 1/2' x 7 1/2' slab. Way bigger than the FB plans. That's with a slab that extends 6" around my entire block wall stand. I'ld like to eliminate that 6" border as much as I can.

Also I'm wondering what height everyone's oven floor is from their slab. FB plans say it's about 40" but that seems low. I was thinking of making it roughly 48". Thanks.

Re: Block Wall

It can be flush with the edge of the slab.

Re: Block Wall

If you cantilever the supporting slab you can place the walls closer, reducing the number of blocks required. Because most of the oven mass is not on the outside, the walls are then underneath this heavier mass. It also reduces the span between the walls which means the slab can be reduced in thickness saving more materials, weight and time.The only downside is that there is a bit more work in setting up the form work.personally I prefer the aesthetics of a cantilevered slab. It just looks better balanced.
