I am just doing a self build and wish to lay solid Oak floors in two rooms,
After reading this forum and your many knowledgable replies, am I correct in thinking that I can lay 50mm kingspan insulation over a concrete sub floor [with a dpm under the Kingspan] then lay the T&G flooring over this with the joints glued,[as a floating floor] leaving a 10mm gap all round the edge for expansion, if so would it be better to lay plywood over the insulation first ??if so what thickness would you recommend, should the boards also be cramped up before glueing???
Sorry for so many questions but I need to get it right.
