HI, Hope I'm posting in the right place. My builder has built a new chimney into an extension I am having. He has used 9" concrete flue liners and enclosed these using masonry and then backfilled the voids with vermiculite.
My concerns are the proximity of the floor joists and also the roof joists almost without exception they are either touching or an inch away. To add to this the back wall has been used as the back of the masory to enclose the flue and where it gets to the wall plate rather than cut out the wood and replace with masonry they have literally built up on it.
I have googled alot and know I probably need to spean with m,y building officer but before I do this and potentially get told to take my chimney down I wanted to know if I have any other options.
My architect by the way had specifed a a doub;le skinned insulated flue. My builder is telling me he is now going to put a double skinned flexible liner down and used vermiculite around this and he thinks thats ok.
Is it? Do I have other options or am I clutching at straws? Any advice greatly appreciated.
