20mm x 2mm PEX-AL-PEX Underfloor Heating Pipe

Designed for efficiency, durability, and long-term reliability, the Alpex PEX-AL-PEX Multilayer Pipe is an excellent choice for modern underfloor heating systems. By combining the strength of aluminium with the flexibility of advanced plastics, this pipe delivers outstanding thermal performance while remaining easy to handle and install.

Manufactured in accordance with ASTM F1281 and EN ISO 21003 standards, the Alpex pipe is fully certified by SKZ, CE, and Gost-R, ensuring consistent quality and safety. Its robust five-layer construction provides complete oxygen and gas impermeability, protecting the heating system from corrosion and maintaining optimal performance over time. The integrated aluminium layer also minimises thermal expansion and reduces pipe memory, allowing the pipe to hold its shape during installation.

Engineered to operate at temperatures of up to 85°C and pressures of 10 bar, this pipe performs reliably in demanding heating applications. It is lightweight yet exceptionally durable, offering excellent resistance to temperature fluctuations, limescale buildup, and corrosion.

Available in a range of sizes, including the widely used 20mm WRAS-approved option, the Alpex multilayer pipe is built for long service life, with an expected lifespan of up to 50 years—making it a cost-effective and dependable solution for underfloor heating installations.
