Hi Patrick On our Noflay stove we don't use fire bricks for the shroud. The unfired bricks are much cheaper about 1/2 the price and usually sourced with lower transport costs. Fire bricks though are more water resistant if used in an outdoor application when tropical rain storms hit. I am an agronomist with some background in soils avidly learning about clay brick production. We made about 150,000 clay bricks this past year. Our experience is to spend considerable time examining the various clay fields in a region as certain clays provide outstanding results. regards roger samson

It is used in many places to line a stove made of steel. But what about on the outside where the flames never hit it. Is there any reason it has to be this special kind of brick? I am thinking, that as long as the flames never actually touch the brick, then any kind of brick can be used.
