I am soon to be fitting solid wood flooring and will be doing this with hidden screws in the tongues of the boards, so I will be using a ply sub-floor on the concrete. (I did this with the other room, same boards, and was happy this way)
I would like to also insulate under the boards but I only have a total of 45mm, with the boards being 20mm.
There was also some signs of damp on the previous carpet, however, I am not keen on tanking the floor as there are a few asbestos tiles left on the floor, and would prefer to leave them alone.
This is what I was planning on doing:
1) Damp Proof membrane sheet (I have a spare roll, unsure on the gauge, but it is thick)
2) Over lap this DPS up the walls slightly to be covered by the skirting
3) 12mm Celotex Insulation Boards - Pressure fitted with the joints taped
4) 9mm Plywood - Screw this ply to the concrete - Leave about 10mm expansion gap
5) Solid Wood Flooring
12mm Celotex + 12mm ply + 20mm Flooring = 44mm
Happy to hear your thoughts to this way of Damp Proofing and Insulating a concrete floor?
