    Default underfloor heating and ply??

    hi all, i have recently built an extension and have gas underfloor heating which sits into grooves if you know what i mean. the builder has layed quarter inch ply straight over this and says it can be tiled on, is he correct or will the tiles lift with being such thin ply? also what is the best adhesive for underfloor heating or is there little diffrence?
    thanx

    6mm ply is next to uselss in tiling situations as far as I am concerned. Would need to be at least double that thickness IMO.

    Hi Chris, quarter inch ply is a big NO.

    How is the ply attached and is it secure? Its too thin for a start as the other guys have said.
    If the UFH is in groves, is it plastic forming boards? Should maybe be screeded over not plyed?

    Alot of questions for yer builder ther.
    Remember flexi addy & grout must be used.

    ok thanks all, if i was to lift the ply and screed it then what thickness is required? i forgot to mention the underfloor heating is set into wood, which is grooved and it seems to be solid.
    thanx all.
