Thermal break between dome and chimney box

Stainless steel at the entry on the floor level is a good idea to prevent abrasion and many commercial ovens have this, but stainless is way more conductive than brick so is somewhat self defeating if the objective is to reduce heat conduction.

A thin piece of stainless in contact with the brick floor will not transfer much heat because the contact point will be minimal less than 1/8 inch X length of steel. and I plan to hold it back with ash gap, which will further reduce the thermal transfer.
