   Hi Richard.

   Rift and quartersawn are the most stable of the cuts.

   And thats all that I can offer.

   Hope that helps.

   *We've had a lot of experience specifying and inspecting wood floors over radiant heating. Best advice is to let the floor aclimate as long as you can. Use a moiture meter often to make sure the floor is as dry as possible, 6-8% if you can, and leave room for it to move (seasonal). Also, you WILL puncture the tubing no matter how careful you are. Keep your plumber's emergency number handy. Your species and cut will also help.Good luck.PS: Also, your 2x12 floor cavity should be well insulated to insure heat aims back in the direction you want, otherwise you will waste a great deal of radiant energy.

   The advice on acclimating is bang on. If you are up for it, finishing the backside of the lumber and even the tongues and grooves (trying not to build up much finish, of course), is about as much as you can do.Re. puncturing the tubing, I can't say I've seen a puncture yet. Maybe I've just been lucky.

   I have installed radiant under fir and my clients really like it.

   The floor is more open now but OK. We found out that radiant isn't suited for night time set back as it takes way to long to heat back up. They also seem to use a good amount of propane but I have no way to compare. There home is on a lake exposed to strong north winds and does have a tough time when wind blows at 10 below. They have mostly cathedral upstairs suite closed off from below with door at stairwell. The upstairs is heated with hydronic base. We haven't discovered moisture problems so far.

   I would value a more in depth opinion as to what you think of radiant and what's the roof condensation problem, etc.

   Also would like your ideas as to the best three heat systems you favor that are practical, etc.

   Thanks in advance, and feel free to start a heat system topic.

   Jack : )

   Hi Jack,
   Too late tonight but I'll get back in the next few days about heat ideas. I think the stuff about condensation isn't serious.

   This old timer is a little nervous about installing this fl. ($12,000 worth) over 3/4 mat subfl. thats glued and nailed to 2x12s on 16" centers at a 14' span. The radiant tubing (2 rows per bay) run thru the radiant plates just under the subfloor. I won't drive the nails thru the tubing. Should I be concerned about how the heat will effect the flooring? Any suggestions

   Thanks........Richard
