Hello,
we've just bought a new house, the current ground floor is concrete and I'm thinking about installing under-floor-heating. I don't want to screed as the reception room areas are too large, (16 2m each of 2) so I was thinking of putting down a DPM with 4x2 sawn battens (at 400mm centres), on top, with insulation between then the ufh piping with wood textured tiles on top of all that.
The thing is I did the ufh in the bathroom on our last house, suspended floor (of course), with 3/4" ply glued and screwed, (about every 200mm), then tiled it, (no primer but used BAL adhesive). It worked a treat and the tiles keep the heat wonderfully well so I'd really like to do it again but this time on a much larger area.
I appreciate there will be very little flexing in the bathroom as the area is not large so maybe I just got lucky.
The question I'd like to ask members is, because of the much longer runs of batten, can I expect much in the way of flexure, I'd expect to put dwangs in at 1 metre.
