    Re: expansion joint?

    I just put a piece of foil to create a slip joint there. You could use the flat stove door gasket material if you wanted to get fancy. There's also a quarter inch version of the insulating blanket, but I'm sure you'd have to buy the whole roll.

    Mick,

    I didn't use one, but when you mortar the brick, you almost get one by default. The mortar isn't going to be solid between the two bricks. I did separate the brick from the flue about two inches and filled the gap with vermiculite/portland for insulation.

    Thanks for the reply ... maybe I should have explained my query better

    I mean where the hearth and the chimney work meets the outer/cosmetic brickwork

    I think I understand your question.
    Insulation goes on the outside of your oven bricks, then the cosmetic brick work. Lots of insulation. Then you can have a gap or not. I don't think it matters. The builders who used stucco to finish the top of the oven used no gap.
    Hope this helps.

    expansion joint?

    Hello

    I've seen some examples (can't remember where!) of a gap between the inner dome and the cosmetic brick work. It sounds logical to have one I suppose.

    Has anyone used one? what did you plug the gap with?

    Any hints-tips will be appreciated
