Using Pex Rail under hardwood flooring

Member Posts: 4
Has anyone out there used Wirsbo Pex rail to attach 1/2 inch Pex to subflooring under hardwood tongue and groove flooring, without using a gypsum concrete overpour? We have the following scenario: Log home with T&G cedar on top of exposed floor beams at second floor, 2 x 4 sleepers (lying flat) on 2 ft centers on top of T&G, 1/2 inch isocyanurate foam insulation between sleepers w/ foil faced up, Pex rails screwed on top of foam to T&G below on 2 ft centers, Pex snapped into Pex rails at 8 inch centers w/ 3 rows between sleepers. Plan to install hardwood over Pex and sleepers as is w/o overpour. Rooms are bedrooms with small amount of windows and 2 x 8 rafters full of insulation. First floor rooms are radiant heated with staple-up from basement below. We really are just warming the floors as the heat loss is not too high, so water temps should not be real high. Possible concerns are any noise from tubing as it expands through PEX rails later. Any experiences, thoughts or suggestions? (A loaded question to be sure). TIA.

Track
We use track on all our Jobs and have had great results! No noise with track if install properly.We screw all our track and we use RTI not Wirsbo.There have been many post on track vs staple up and how if the load load is over 15 btu's psf track wins hands down. Second surface temp should not exceed 80 f but I have read where some have used higher temps with no side affects, so you may be able to get more btu's psf. So to answer your question track works great!0
