Grant Uflex PEX-AL-PEX 16mm x 100 Metre Underfloor Heating Pipe

The Grant Uflex PEX‑AL‑PEX 16mm Underfloor Heating Pipe (100m Coil) is a high‑performance multi‑layer pipe designed to deliver exceptional strength, stability, and heat transfer in modern underfloor heating systems. Constructed using a PEX‑AL‑PEX composite structure, it combines the flexibility of plastic pipe with the strength and oxygen‑barrier properties of aluminium.

Engineered for seamless integration with Grant Uflex underfloor heating systems, the aluminium core significantly reduces thermal expansion while maintaining excellent shape retention during installation. This makes the pipe easier to lay accurately while ensuring consistent long‑term performance.

Supplied in a 100‑metre coil, the pipe is ideal for medium‑sized heating zones, offering reliable flow rates, efficient heat distribution, and long service life in both new‑build and retrofit installations.
