If I put insulation under floorboards, would I need a DPM to protect the battens?
What we have atm is a bare concrete floor, so I'm planning to screw battens into it, put insulation between them then nail floorboards on top. Am assuming the same vapour barrier considerations apply as with dry lining walls. Is this correct, or don't I need to bother?
And before anyone suggests it, we don't like laminates... :)
