   Will it really be "concrete" or will it be Gypcrete(tm) or similar? what will the finished floor be? if it is finished concrete or tile, cleaning up the mess the drywallers leave will be some work, if carpet or hardwood you'll just need to scrape off the lumps before putting down the finished floor. If the concrete is done first you'll have to be sure there is somthing to nail the bottom of the drywall to, since concrete will cover a single bottom plate. In the houses I've been involved with, the drywall was done first. (but painting was done after the 'crete)

   Jay-

   Thanks for the info. No, i'm not using regular concrete, but gypcrete TM or a similar medium avaulable in Wash. state. My finished floor will be both tile and carpet. It makes sense to install the drywall first and avoid cleaning so much of the drywall mess.

   Thanks,

   Terry

   I have a Wirsbo radiant floor heating system, retro-fit under wood floors. I have found that even with the thermostat at a constant temp, the system makes a lot of noise as the pumps kick on. Will lowering the temp of the water lessen the noise? Will Anything? Also how much of could I decrease the temperature at night without over working the system to bring the temp up to a normal temp? Or should I leave the thermostat at a constant temp?

   *Is your tubing installed in those aluminum heat sink channels? If so the noise is probably the tubing creeping as it expands with the start of a heating cycle. I have a neighbor who complains about the same thing. My radiant tubing is also under the subfloor (twin-tube "Radiant Roll") but is simply attached to the plywood and insulated underneath with foil faced FG, reflective surface facing up. It's very effective and absolutely quiet. Without undoing your installation you could try lowering the temp. of the water in the system so it's running more or less continuously to provide your heating needs. That would eliminate the expansion and contraction noise.

   I am installing radiant flooring in my house. I have heard conflicting ideas regarding the pouring of concret in relation to the installation of dry-wall. Pour concrete before or after dry-wall? Please send any ideas.
