Wall and Ceiling Shielding Question

[JLB1]

I am building a sauna with a wood stove. I am installing wall clearance reduction shields on two walls and on the ceiling. All will have min. 1" air gaps. My question is where the wall and ceiling shields would meet do I butt the wall and ceiling shields together, or leave a gap?
Thanks, Jim

Leave at least a one inch gap. You want the air to flow freely
behind the wall shield. In order to do so, it needs to be unrestricted,
top & bottom...

Thanks Bob!

I asked the stove manufacturer (Kuuma Stoves by Lammpa Mfg.) and he said butt the ceiling and wall joints together.

That seems counterintuitive to airflow but if it's what the manufacturer recommends then?

Here is how I did my roof shielding that had to step down to cover a duct.
