Watts Radiant RadiantPEX-AL is a long-lasting, durable composite tubing pipe specifically developed for radiant floor heating, snow melting, and distribution piping. This unique 5-layer pipe's definitive feature is a layer of aluminum sandwiched in between two layers of durable cross-linked polyethylene rubber. This layer of aluminum gives the tube the ability to hold any shape it is formed into, allowing installations of PEX-AL-PEX pipe to be completed significantly faster than installations where standard pipe is used. The layer of aluminum also reduces expansion and contraction distance to an absolute minimum, making RadiantPEX-AL a steadfast, long-lasting piping solution for nearly any radiant heating application.
Holds its Shape for Easy Installation
Once bent into a certain shape by the installer, RadiantPEX-AL will hold that shape until it is bent otherwise. This allows one person to install RadiantPEX-AL faster than nearly any other PEX tubing. The reduced installation times translate to an effortless installation for your contractor and decreased costs for you.
Minimal Contraction and Expansion Distance
PEX tubing normally expands and contracts as the temperature changes. The layer of aluminum in RadiantPEX-AL tubing reduces these fluctuations in size to an absolute minimum. This reduces wear and tear on the hydronic system, reducing long-term maintenance costss.
Silane Cross-Linking Construction
RadiantPEX-AL is manufactured using a superior manufacturing technology called Silane Cross-Linking. This manufacturing process gives the two PEX layers in the tubing much higher burst strength and provides superior anti-oxidant protection.
Highly Corrosion Resistant
RadiantPEX-AL tubing has unparalleled corrosion resistance, improving durability and further minimizing needed maintenance on the tubing throughout service life.
