We will be installing solid ash strip flooring, pre-finished with micro-groove, over radiant in 1/12†concrete. We will be attaching directly to 2X sleepers placed at 1’ intervals. The main floor (not a slab) is over the basement below which has radiant in the slab. The heat on the main level is on at a modest level, all concrete was poured approx 2 yrs age. Drywall finished months ago so major moisture is not a concern. The flooring has been on site for many months and has been acclimated.
Questions:
- Moisture, should we still do a poly vapor barrier? (note: the concrete was pulled flat but not troweled so the surface could puncture the barrier)
- Sound Proofing, would using it impede heat transfer from concrete to wood thus rendering the system less efficient? If not, is some types more preferable for radiant heat?
- Attaching / installing, since it is over radiant, we are looking for as much holding power as possible. Should be use square cut or staples? Should we use adhesive to assist nails? If so, are there any that are better than others for radiant? Definitely interested in the least noxious.
Thank you for any assistance you can provide.

I think that your answer should come from the manufactor of the flooring, they are not the same. Most have a method that they require for their product. If you have a 800 number call them and you would't believe the info. you can get for free. Luck.
