Dome walls on brick floor

[spinal tap]

The FB guide recommends building the wall on the insulation for maximum insulation. Is there a downside to building the walls onto the hearth brick floor? My blankets will come down to the bottom to meet the fiber boards so the whole oven will be encased in FB boards or blanket.

Thanks,
Nate

Many have built it that way. The hearth has to be on insulation so the dome is insulated either way. The only downside is if you needed to replace a hearth brick that the dome is sitting on. Not sure how often that would be required...

Can't be very often. I remember only one instance on this forum that someone has had to do this.
