Wirsbo Joist Trak, 1/2" Heat Transfer Panel

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

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.

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.

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.

Used it for a retrofit radiant heat project, with 1/2" pex tubing.

Under sub floor thermal heating.

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.

Fast delivery and easy to install.

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

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!
