Afternoon everyone,
I'm just preparing our existing, uninsulated (we think) floor slab for imminent installation of underfloor heating (booked for c.2 weeks time).
Short version: I'm an idiot and didn't consider everything.
Long version: We are limited in options for height build up due to existing features with a maximum of c.70mm finished floor level so the plan has been 30mm PIR, 15mm UFH pipes clipped, 35mm liquid screed = 65mm. This gave us 5mm for LVT finish and actually then a fairly decent amount of contingency up to external door thresholds without getting up to the opening of the doors or beading of some floor to ceiling windows.
BUT, what I did not consider is one of the external doors is inward opening! So the height for that one is much less. Bottom of the door is c.60mm off the floor.
So I'm rapidly having to look at alternative options and was wondering if anyone could please offer any suggestions?
Currently thinking we'll need to go with routed EPS panels to 'lose' the pipe height (the 35mm specified for screed is because minimum thickness is 20mm, so 20mm over 15mm pipes = 35mm). I've found a couple of potential options but nothing that jumps out.
Any suggestions of alternative build up very gratefully received.
Thanks in advance.
