Hi I'm looking for a little advice, I moved to this new (to me) house and replaced all the doors/windows and want the cladding replacing, I had a quote of £6k and I think they thought I was daft, I priced up the materials for fibre cement board and celotex etc and there isn't £2k worth of material so £4k for 2 days work, nah.
I am very handy but at 52 thought I'd pay someone else but there having a laugh so I'm going to do it myself. The existing is batons onto breeze block then wooden cladding with poor foam insulation between, then very cheap UPVC clad over that, my plan is to rip it all off, re-baton and put in some celotex 50/100mm ?? then vapour barrier and clad with cement fibre board cladding, I think I get my head around it but am unsure of what thickness celotex to use, can anyone advice and just confirm my plan is sound - so - strip off all the upvc, then all the wooden cladding, remove all the poor foam insulation, strip off the batons, take back to the breeze block, then new batons, fasten celotex direct to the breeze blocks the same thickness as the batons, then vapor barrier, then say 1" batons on top of that to to fasten the fibre board to with a mesh vent on the top and bottom, I do need the gap between the celotex and cladding don't I ? if that's correct is there any stipulation on how thick the celotex should be or is it the more the merrier ? I would greatly appreciate any advice so I don't stuff it up
