Behind the kitchen rayburn is a one inch gap
then a double brick wall (no cavity).

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.)


For 2 sq yards I wouldn't bother.



But as heatloss is proportional to temperature difference
and the back of the rayburn may get quite hot
there could be quite a bit of heat loss through the walls,
worth doing something I think
(as well as increasing the air gap)
