Good basic product, easily improved
Installing these under a new bathroom sub-floor. In this application, heat conduction into the floor above is everything. I found the holes in the Joist-Trak to be be too small, and too few, so I drilled out the existing holes to accommodate a #10 screw, and added hole pairs between the pairs of factory holes, a bit closer to the tube channel. This should increase the conduction into the floor, and improve overall effectiveness and efficiency. I will follow up with 10" of AirKrete cementitious foam insulation to make sure all the heat goes up into the floor, not down into the room below.

Nope nope noooooooope!
I ended up using thin gauge snap on style plates as the Joist traks don't full cover the pex, have to be tediously screwed to floor rather than power stapled, and they are rediculously over priced. I heated a floor section side by side with these and snap over plates and couldn't tell any difference in the heating effect above the floor. The only nice thing about these are being able to install them before running pex, but otherwise not a great investment.

Properly product
Don't try to do with another product, this one it's the best one for radiant heat track above plywood.

Plates work as expected.
Second time purchasing these plates for subfloor pex. They transfer heat much better than just staple up. Our home was entirely fitted with Zurn Pex B before we purchased it. Pex expansion ticking noise at cold start up is noticeable but does not last long. The factory mounting holes should be larger. I drilled ours out to accept a #8 screw.
SupplyHouse pricing is competitive and shipping speed is always impressive.

Worked great in my application
No noise when used with Pex al Pex tubing. Worked great for radiant heating. I added aluminum sheet under floor joists then put these up as well for more heat transfer underneath the floors. Perfect set up.

Good heat conduction, sharp edges
I got these mainly to hold the tubing up against the floor until insulation could be installed. I did not expect the thin plates to provide much heat transfer, so I only used them at long intervals, enough to hold up the tubing. Later, using a thermal imager, I was surprised to see how effective the plates are - you can clearly see their outlines in the thermal images.
My main concern is the sharp edges. We ran the system for some weeks before the insulation was installed (was actually surprised at how effective they were at heating before the insulation was installed). Discovered that with expansion and contraction, if the tubing did not exit the plate completely straight that the edge would abrade the tubing. So be sure to make long loops at the ends, not short ones. I became concerned about the long term prospects, so pulled the tubing down at the ends of the plates, so that the tubing exits the plate before the sharp edges. Not sure it the tubing will remain in the tract over the long term - guess I'll find out.

Great product. No issues, works as intended.
Used it for a retrofit radiant heat project, with 1/2" pex tubing.

I would buy this again
We used thousands of these panels. They work very well if they are installed per spec. You must insulate under the joist where panels are located to perform the best.

Perfect for underfloor heating zone retrofits.
As described, works w the Special heat transfer PEX tubing. Added hot water heat zones to my daughter's bedroom, bathroom, and kitchen floor.

Good product with excellent customer service
I have purchased this product before and wanted to expand my floor heating system. I order 14 but received 12. I called customer service and they shipped the missing 2 right away, helping me complete the project with minimal delay. Never have I had a bad experience dealing with Supplyhouse!

Q: Q1: Any recomendation on spacing of the Heat Transfer Panels under a subfloor of 3/4 inch, plus 3/4 inch of plywood on top, plus a 1/2 inch for flooring (ie. 1.5 inches of plywood plus 1/2 of flooring?) Q2: Is cork flooring an option when using Heat Transfer Panels under a subfloor regarding heat transfer and comfort?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffProper spacing is based on joist bay size. The cork will slow the heat from coming up, so you have to account for that when designing your system.

Q: house built around 1865. joist spacing varies in different areas from 8", 12" and 16" depending on the span. would I need to put in 2 trak's in each bay?

Q: Can I use this trak under 3/4" sub floor with 3/4 tongue and groove fir over top of it? Should I space the pex lines closer together (12") to increase the heat gain and defeat the insulating property of 1.5" of wood? Thanks
Asked by Homemade 15 years ago

Verified Reply- PexSupply StaffJoist Trak panels are meant to be used under the sub-floor in the joist bays.

Q: im am being put of from using the product as people are telling me about squeaking noises.i want to heat 1500 sqft and cant screw it up ,is joist trak the right material to use
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffAny squeaking noises come from the metal expanding. They are generally only an issues when installers do not secure the panels using all the screw holes.

Q: When our radiant heating system was installed years ago, there were only plastic hangers used to attach the PEX tubing. I'd like to add the heat transfer panels to make the existing system more efficient and even out the floor temp. However, since it's a 100+ year old house, the wood flooring is not laid on subfloor but directly on the floor joists. Would the transfer panels make the wood flooring too hot?
Asked by DDCC 15 years ago
Add your answer
Verified Reply- PexSupply StaffThe panels would not make the wood flooring too hot as long as the water temperature is below 140°F and the surface temperature is below 82°F.

Q: Can I use spray foam directly over the panels and tubing (need some kind of vapour barrier in this application) or should there be an air space between the floor and insulation in the joist space?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffNo gap is necessary. You can use spray foam with these panels.

Q: when installing joist track under 3/4" hardwood does the hardwood have to be installed first to prevent nails from hitting the pex or does the joist track maintain enough room so the nails or stapels won't hit the pex pipe?

Q: Will I get heat thru 3/4" advantec with another layer of 1/2" plywood and a layer of carpeting, if I use radiant panels. How much material can radiant heat penetrate thru and still be effective?
Asked by Mark 15 years ago
Add your answer
Verified Reply- PexSupply StaffYou are not going to get the greatest amount of heat through the insulation of all those layers. The rate would be based on the BTU load of the space, the R-valve that needs to be overcome, and the water temperature of the system.
