Grant Uflex PEX-AL-PEX 16mm x 500 Metre Underfloor Heating Pipe

The Grant Uflex PEX‑AL‑PEX 16mm Underfloor Heating Pipe (500m Coil) is a premium, multi‑layer pipe designed for large‑scale underfloor heating installations where strength, stability, and installation efficiency are essential. Manufactured using advanced PEX‑AL‑PEX composite technology, it combines the flexibility of cross‑linked polyethylene with the rigidity and oxygen‑barrier protection of an aluminium core.

Purpose‑engineered for use with Grant Uflex underfloor heating systems, the aluminium layer significantly reduces thermal expansion and provides excellent shape retention during installation. This makes the pipe easier to lay accurately over large areas while ensuring consistent flow rates and long‑term system performance.

Supplied in a 500‑metre continuous coil, this pipe is ideal for extensive residential or light commercial projects, helping to minimise joints, speed up installation, and enhance overall system reliability.
