   what are you doing ?

    are you going to take up the 5/8 ply ?

    are you going to take up the board sub-floor ?

   if you are not taking them up , i would lay it opposite the last layer of ply... OR.. whichever way was going to break the joints the most..

    OR.... whichever way was going to give you the smoothest floor..

    if you are taking up the 5/8 ply , i would lay the advantech long axis perpindicular to the sub-floor..

   Yeah Mike I am  taking the ply up. Am redoing the kitchen and there are alot of squeaks etc. Another reason is when they put the ply down they lined up all the joints, never offset a 1/2 sheet.

   so.. try to make sure you offset all joints of the advantech from the joints of the 1x subfloor.. renail any loose 1x.. and use a good construction adhesive.

   .... should be fineMike Smith   Rhode Island : Design / Build / Repair / Restore

   Mike; I was thinking of using 2 layers of red rosin paper instead of adhesive. The basement is damp and thought that would help?

   ok.... no adhesive... but make it two layers of 15# felt instead of red resin paperMike Smith   Rhode Island : Design / Build / Repair / Restore

   Mike ; I have thought of putting radiant floor heat in the joists from underneath. Would like to put it in the top but, 5/8" I doubt is enough.

   Would the tar paper bother if I did put in radiant? Odor problem?

   i don't know.. you are introducing one new variable with every post.....

    ok... so , with the radiant heat , you may get some outgassing , so go back to the resin paper..

   anything else you'd care  to disclose ?

    how will you insulate the radiant floor ?

   Havent got that far yet Mike. Any suggestions? Or methods? I still have to get the floor down then the cabinets made and installed, or about in that order.

   PEX in the floor has to be done now. Pex under the floor can be done at a later date. Any suggestions on brands? Wirsbo etc.

   With RFH, omit the felt and go back to red rosin paper.

   Do a staple-up, you can buy a PEX staple gun and staples from the tubing supplier or on-line. Wirsbo is good tubing.

   To insulate underneath the tubing, use half-inch (or one-inch if you desire) foil-faced polyisocyanate insulation. Rip it into 8' lengths slightly wider than the space between the floor joists. Tuck it up, friiction-fit, right against the staples that are holding the tubing to the underside of the subfloor. Alternate method is to cut the plyiso about a half-inch less than the joist bay width, then insert it and use canned foam to foam both edges between the polyiso and the joist. Half-inch can be friction fit easily, with thicker boards it's sometmes easier to foam them in place.

   For an unheated basement, add unfaced R-19 under the polyiso, tuck the FG against the polyiso.

   Mike , Mongo  I appreciate the help. Sometimes its the little details that will get you.

   Are there any sheathings similar to Advantech made by other manufacturers?  Does it matter with the Advantech which side goes down? Seems like one side is slightly different in texture.

   Mike; I just looked at the Advantech, there is no pattern at all on mine!
