doing some reading it would appear ,if you believe the hype, that a passiv house can do without UFH I find this hard to believe and would welcome all views on this subject my thoughts at this early stage are to fit UFH pipes to slab anyway -at least . I have even read that next year there will be a graphene heater element that will work with tessla power wall and solar Pv -- that too sounds a little star trekish

durisol is maybe front runner for my projects ,but may go SIPS. on paper durisol if roughly cement rendered both sides to seal them give best "u" value of anything ,as far as i can find ,presuming you beleive what they all say and add a layer of PIR on outside and you got passiv house although they say no bracing is needed they also say only 4ft per pour. my thoughts ,and correct me if you disagree ,why not just use a little low expansion foam or "no nails" as you lay the blocks --that should help with keeping them in place

Hi, i,m a 67 year old finally getting round to building my own house and along with brother and one for him as well 2 x 1 acre plots bought in s/w scotland overlooking the river cree estuary on the solway with outline planning already --now the problems start .LOL now its trying to sort out the best way to proceed --been hunting internet for a few months now already so expect lots of questions been in the motor trade for 40 years , so plenty of hands on engineering experience , in performance tuning conversions and racing , last thing we built was our garage about 30 years ago 30m x 24m portal frame unit and then total rebuild on a petrol station .but never a house ,so far OH and built a couple of PFA aircraft as well, a kit fox and a europa ,fingers getting itchy for a different challenge
