Wood floor over concrete

[Deleted User]

and the heating system perform very well.

What we did not know in the early installations is that untreated lumber,
(particularly as the cost conscious contractors always wanted to use up 2x4s left over from forming up concrete) can, under the right circumstances, completely dissappear in the from of dry rot. In a project that I built and maintained for a long time I watched a 2 x 4 carpet nailing strip literally turn to wood powder during the ten years thatI was involved with that building.
In construction we never place untreated wood in contact with raw concrete, even if the concrete is scheduled to be in a warm dry place.

Just something to think about.

I was asked to bid

on an addition that will have a concrete slab. They want a hardwood floor over top of the concrete. They wanted an embedded tubing radiant system, but I am thinking a system on top of the floor (susch as quik trak) would be better. I worry about air gaps between the concrete and hardwood floor causing diminished capacities. Also I assume they need to put down something to nail too, and that would cause more resistance to heat transfer. Am I being too cautious? The quik trak system is much more expensive than tube in slab. What is your thoughts on the subject? WW
