Behind the kitchen rayburn is a one inch gap

I'm swapping it for a newer one,
so now is the time to insulate behind it.

3 inches of kingspan then plasterboard is one idea.

But then I wuuld lose 4inches of kitchen.

any better ideas?

(As its only 2 square yards price doesnt matter.)

Fibreglass or rockwool must be the ones to go for, behind PB
