side wall chimney. by: simmo
Hi I have the same plan for our garden house/Golf hut out here in the Correze in France.
I plan to fit a 125mm pipe though the 19mm side wall and have all the bits needed. Trying to get a system to carry the pipe though the wall safely is the bit i'm having difficulty with.
I would have thought a simple kit with an adjustable hole for different size chimey pipes would not be beyond our engineering boffins but I have not found one in the UK or France yet.
