The airspaces only need to be a couple of inches.
The shield could even be a drum lid
Yeah, I was planning on still using the fire bricks(stove bricks) under the UDS for air movement, and then the tile and grout, cement board.
I had the UDS on the fire brick, just like these
and needless to say we now have a hole in the back deck.
I know with proper use of the UDS, i would not have a problem with just continuing to use the fire bricks but to have a sense of safety if my roommate decides to try and use it, even after he has been banned from bbq'ing again, lol. I figured i would add a another safety barrier and something that will cover up the new wood that wil be replacing the burned wood.
