I've now got to the stage of having my blocks up through the ceiling and roof and in the process of rendering the exterior. I bought a few bits from Gedimat to support the chimney downstairs (a metal support for a chimnee pignon), a chevetre for going through the roof and an embargement to seal the roof. I have a couple of questions though ..... Is there something I should buy to hold the flue pipe in the centre of the chimney ... or doesn't it matter? Is there some sort of clamp or connecting thingy to hold the sections of inox pip together? Or just plug them together with perhaps a little refractory mastic? Many thanks Dave S

Hi Folks. A simple question, if you know, I'm sure! I've bought a woodstove and currently have no chimney, so I'm building one! I was going to use the chimney blocks that are readily available at the builders merchants, supporting the stack on a pignon at the bottom and a chevetre at the top. The question I have is, do I need to use any special mortar to 'stick' the blocks together or will a standard cement based mortar do? I am going to use the nice shiny inox tube from the poele to the chimney and a slightly cheaper version up inside the blocks to the top. The chimney will start in the downstairs ceiling, probably surrounding the pipe with some fireproof plaster board .... when I get round to putting a ceiling in! When the stack emerges on the roof (to go 40cm above the ridge line) i was going to render it and fit some sort of 'flashing' to make it water tight over/around the tiles. Any advice on what products to use for this 'seal' would be helpful too. Many thanks Dave
