going around in circles and need opinions/advice about underfloor having read previous threads.
have hardcore, blinding, radon barrier, 120mm aeroboard platinum.
yesterday i put underfloor piping on top of the aeroboard.
i have 134mm left to get level with the external walls.
option 1: easiest
if filled with concrete that would be about 5 1/2 inches of concrete so im just wondering if that is too much? my plumber thinks this would be ok.
option 2: pain in the ass
the other option would be to take up the piping (half days labour to put down) and put another layer of 60 mm aeroboard (cost of additional aeroboard) which would leave the screed at 74 mm. worth it?
option 3
having read other posts i have decided not to put battens and solid wood floor above a 74mm screed, due to its stopping of heat travelling up.
i have also heard of putting a concrete sub floor, then insulation then screed, but this would be difficult at this stage....
is the makeup of layers ok? i have heard/read a lot of different opinions.
is 5 1/2 inches of a screed ok?
what do you think, its these things would have you awake at night!!!
