Hi all quoting for job in kitchen and customer wants UFH. its 30 sqm very odd shape going from kitchen to conservatory. so normal probs floor height issues. 6mm thermal boards down, UFH down, self level, tiles comes to about 23/24 mm. kitchen is floorboards conservatory is concrete so question is im concerned about how the 2 substrates react to UFH. Is thermal boards on there own ok? or do i need ditra on top as well to help with the movement? floorborads when UFH is on will do one thing concrete will be doing something else. Its alot more money and raises the floor level again if I have to put ditra down. im sure somebody has had this prob. cheers
