OK next question...
On the Ephrem 2061 which I shall be using, the top of the arch forms the front of the vent. The chimney will sit on that, with some kind of thermal gasket. Therefore, I am undecided as to whether to use dense firebricks or engineering bricks for the arch. Either way I am planning to incorporate a 10mm thermal break between the arch and oven body, packed out with stove rope. The front wall of the enclosure will be built around the arch, and therefore I don't want it to get too hot, since it will be tiled. I would prefer the appearance of smooth engineering bricks for the arch, with matching bullnose bricks for the landing. The thing is, will they take the heat?
I've thought about a short firebrick arch, with a full-depth engineering brick arch in front of that, each with its own thermal break, but this is where the design gets out of hand. Any clues?
