    should engineered flooring be used as opposed to well dried/aired solid flooring
    especially if the heating will not be on. Or would i be taking a big risk solid flooring.
    also, as the adhesive for flooring is v. expensive (averaging €150 for tin to cover 10m2): would it be an idea to glue down battons to the slab and nail flooring to the battons....cunning plan or not???

    Interesting question and I think the jury is still out.
    Wood by its nature, moves. Some species move quite alot.

    Semi-solid had been used for years and works fine.
    The ply backing allows for expansion and contraction.

    Special glues are expensive, the floor must be sealed with a special (expensive) sealer too. It seems to work fine. I have seem it in use.
    Mosting with hardwoods, which tend to be more stable (less movement).

    Glue battens to slab... might work, allowing for patio door / ceiling heights etc.
    A thin batten, extremely well glued.

    Talk to a number of specialist under-floor heating specialists, glue manufactures, timber floor manufacturers etc.

    I toyed with lots of ideas, finally settleing on Oak semi-solid. Its fine.
    Hopefully someone on the forum has personal experience of gluing timber to underfloor heating slab.

    semi solid on thin purpose made slip membrane is the way to go . a well known bray based ufh supplier also stocks timber flooring and a waxed paper slip membrane . not saying you restrict your choice like this , but make the timber flooring supplier confirm in writing , that their materials are suitable

    I personally would avoid gluing solids over UFH screed with 1 exception - in the case of herring bone or parquet type flooring , the combintaion of all those timber joints , together with the adhesive should work fine . Again , make the supplier aware of the application

    I have found battens below the flooring to be a complete pain in the swiss. difficult to secure battens , can cause air spaces which inhibit the heating and leads to lots of hassles with differing screed levels so the timber floor level matches to adjacent tiled floor level
