laurenco Posted March 1, 2018 Share Posted March 1, 2018 Apologies if this has been asked before but I'm looking to install UFH upstairs on a new build. There seems to be a million dry and screed options. Can anyone recommend the best / cheapest system to go on posi joists? Link to comment Share on other sites More sharing options...
JamesP Posted March 1, 2018 Share Posted March 1, 2018 (edited) Have a look at Nu-heat ( https://www.nu-heat.co.uk/underfloor-heating/floor-constructions/joisted/ ) for some UFH options. They do a a clippa plate system which can go between or over joists. I will probably be using the polystyene panel system which sits on top of the floor decking as I have already fitted the deck, increases the floor depth by 25mm. Lots of systems out there to look at.

Nickfromwales Posted March 1, 2018 Share Posted March 1, 2018 UFH aluminium spreader plate is what I'd recommend. If you can add 2x1 battens then you can leave a gap each end to loop the pipes which is 1000 times easier than looping under. 1 Link to comment Share on other sites More sharing options...
JamesP Posted March 1, 2018 Share Posted March 1, 2018 Below is my first floor option. Polystyrene with aluminium spreader plate. 1 Link to comment Share on other sites More sharing options...
