Dome complete and just about to start curing fires this weekend. Now the chimney…
I like the idea of a brick one. But that means weight. But then I thought – hang on, I’ve quite a few Hebel blocks left over from insulating the hearth. If I cut those up into brick sized pieces and form a chimney with them, the size is such that if I line up the inside of the Hebel ‘bricks’ with the inside of the opening, then it leaves 25mm on the outside which I could clad with either tiles or maybe 25mm slices of brick so it would look like a proper brick chimney. And Hebel would be easy to form to suit the curve of the arch on the first course.
I was thinking of using high temp mortar for fixing the Hebel and then maybe Home Brew for the cladding. I think it the cladding would give it enough structural stability and the whole thing would be a lot lighter and effectively insulated into the bargain.
Anyone any thoughts?
