Timber floor on battens fixed to concrete subfloor - is ventilation required?

rustynutz

I put down timber floors in my house when it was been built a 4 years ago. In three of the rooms I fitted solid ash on timber battens fixed to the concrete subloor so the make up of the floor is starting from the bottom:

Concrete subfloor (raft)
1000 gauge polythene
2x1 battens fixed to concrete
2x2 battens running at right angles to 2x1
insulation (50mm polystyrene) between 2x1
and 18mm solid floor secret nailed to 2x1

I never considered underfloor ventilation at the time as the void was so small between concrete and floorboards (4 inch max) I didn't think fitting an air vent outside would serve any purpose but now I'm not so sure if there could be a build up of moisture in the timber causing rot down the line.

Does anyone know if underfloor ventilation is required in these circumstances?
I don't want to fit them if I don't have to as they will just cause draughts I'm thinkin.

All advise welcome:D

I put solid oak flooring throughout my house and laid them on 2X1 battens on top of a concrete floor, that was 12 years ago and they're fine, I really don't think you'll have a problem, unless you already have a damp problem in the house?

No, the house is only a few years old so no dampness at all thankfully, might be ok so

Same here, have solid oak, prefinish down over 10 years on 2x1, never had a problem.

I wouldn't worry if I were you.

Good, just what I was hoping!
