How-To Articles


    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.
  • 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.
  • 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.
