I have a solid floor with the old type hard composition Marley tiles
on top.
Is it necessary to put a polythene damp proofing membrane down before
laying insulation material & then the planks etc. ?

Thanks for any help

One question...
Did you have carpet down on this floor?

Yes carpet is down at present
