RadiantPEX+Cross-linked Polyethylene Tubing with EVOH Barrier
The cross-linked molecular structure of RadiantPEX+™ offers toughness, flexibility and lasting durability. It is corrosion resistant, virtually maintenance free, and withstands temperatures ranging from below freezing to above the boiling point.
RadiantPEX+ combines all of the traditional advantages of plastic PEX tubing, but with an EVOH oxygen barrier. Adding protection against corrosion for the various ferrous components of a heating system.
RadiantPEX+ is manufactured to meet the American Standard Testing Method for cross-linked polyethylene tubing (ASTM F 876-09), and all sizes are made to the Standard Dimension Ratio for plastic pipes, SDR 9.
Keepin' it real… quiet.
Radiant systems that use PEX are known for comfort, but are also notorious for noise. As the system starts warming up, the tubing expands causing it to rub aginst the floor and fasteners holding it. The friction from this rubbing creates ticking or creaking.

You won't get that with RadiantPEX+. We've added an extra low-friction layer that greatly reduces expansion noise.
Comfort should be felt, not heard.
RadiantPex-ALCross-linked Polyethylene Tubing with Aluminum Layer
The RadiantPEX-AL Advantage
RadiantPEX-AL is a composite pipe engineered for radiant floor heating. It's proven, long lasting and maintenance-free. Installers like it because it's lightweight, durable and can be shaped to fit any jobsite. The aluminum layer protects boiler systems against corrosion and it has superior temperature and pressure ratings.
Built To Last

RadiantPEX-AL is manufactured to American Standard Testing Methods for composite radiant pipe and fittings (ASTM F-1281-05). Included are requirements and test methods for materials, workmanship, dimensions, environmental stress cracking, sustained hydrostatic pressure strength, thermo-cycling resistance and bend strength among other tests. RadiantPEX-AL meets or exceeds these specifications.
Features
- Best of Both Worlds - Strength, memory and pressure rating of aluminum with the corrosion resistance of PEX, inside and out.
- Bends To Your Will - Rigid enough to hold itself in place for straight, neat runs with enough flexibility to go around obstacles without additional fittings.
- The Strong Silent Type - Doesn't expand as much as PEX, resulting in less noise in an underfloor application.

Clean
Unlike metal alternatives, PEX plumbing systems are immune to corrosion and mineral buildup.
Efficient
Uponor PEX plumbing systems retain more heat in hot-water lines and resist condensation on cold-water lines.
Guaranteed

Why radiant floor heating?
Unlike forced air heating systems, radiant floor heating provides the ideal personal comfort zone, keeping your body warm without heating air above your head.
How does radiant floor heating work?
Warm water, 80° to 160°, circulates through barrier tubing in the floor. You can use a variety of heating sources, including a boiler or you can use a water heater.
Why is radiant floor heating so comfortable?
Radiant heating warms your feet, body and the objects around you. This allows you to keep temperatures lower to maintain the same comfort level. |
