12mm Pert-Al-Pert Underfloor Heating Pipe – 80 Metre Barrier Pipe Coil

This 12mm Pert-Al-Pert multilayer pipe is a high-specification 5-layer composite pipe, purpose-built for water-based underfloor heating systems. It outperforms older PEXa and PEXb pipes, offering superior flexibility, thermal performance, and long-term reliability.

The central aluminium core forms a 100% oxygen barrier, protecting boilers, pumps, and other metal components from corrosion. The inner and outer PE-RT layers provide temperature resistance and flexibility, making it easy to install with tight bends and minimal fixings.
