framing walls on a concrete slab with radiant heating
I recently replaced the slab on the ground level of my split level home. I ended up gutting the entire level, doing it again from scratch. The new slab has radiant heating.
The contractor (IMHO) didn't do a good job with the framing -- it wasn't straight or square. I also have pocket doors, meaning the framing by the doors are 1 1/2" thick (they used 6" walls). When I looked at it with a straight edge and square, they agreed, and banged it into place (they used liquid nails). But "banging it" after the glue dried would "upset the bonds which formed" (IMHO).
In addition, too many stubs were warped, which caused other headaches (they ripped 2x6's, I don't know why they didn't just buy 2x3's unless they have a saw fetish).
From what I found it, you can use IR imaging to know where the radiant heating tubes are, so you can use mechanical fasteners where there are no pipes (I told them about this after the fact and they expressed "surprise"). They're hoping the tile holds the walls in place (but I think the walls should hold themselves).
