So I’ve just been reading about this and there are sites Do I need a vapour control layer above the joists? A lot of sites suggest this with a vapour permeable membrane below joists. I will be working the the void so the control layer will be somewhat impossible. thanks

Ok. That doesn’t sound like too big a job. Not sure what conditions the rates were gathered from but they stated that an independent UCAS test was carried out on the panels and that’s what they are working from. I guess belt and braces won’t hurt thanks

So I’ve been back in touch with the UFH company to voice my (most people’s concerns regarding downward heat loss). They have reassured me with the system I have bought is designed for no insulation. they have said I can get 75-80w/m2 output with wood finish and 96w/m2 output with tile finish. Reckon I’m happy with that!!! also for any technical people reading this thread, the R-value of the panel is 0.447 (whatever that means ?) cheers for everyone’s help

Thanks for that info. With that in kind I might look at a better insulation under the floor. cheers

Ouch. Don’t say that.... I asked about that same issue multiple times to the supplier and they reckons it’s designed for it. will the plywood offer any insulation? Other than that it’s asking somebody to spray something to the underside of the floor boards at a later date as I don’t have time to sort it now!

Thanks for all the reply’s everyone. So there isn’t any underfloor insulation. However, I have been assured that the ufh overboard in buying doesn’t loose that much heat downward!!! As for levelling off the 2cm loss...I reckon I will just leave it and plywood over the floorboards and then sick the ufh low profile boards on top. Not sure why there is a 2cm discrepancy...fingers crossed it’s not down to dodgy foundations. I have already taken of the skirts and arcs so that’s not an issue. fingers crossed after reading all the advice I’m making the right choice and it all goes well!!!! cheers

Could I use self levelling compound to level off??

so the heat will work efficiently with the drop...that’s great news. what would annoy you, the Unilever floor or having rectify it? Thanks for the reply btw

So I’m got to lay overboard Wunda UFH. My subfloor is Woden floorboards. Unfortunately the floor drops by 2cm on one side. This is a level drop throughout the room so the floor is all 2cm lower on one side. So, firstly will this matter? If it does what’s the best, easiest, cheapest way of levelling off? hope somebody can help thanks
