Grant Uflex PEX-AL-PEX 16mm x 250 Metre Underfloor Heating Pipe

The Grant Uflex PEX‑AL‑PEX 16mm Underfloor Heating Pipe (250m Coil) is a high‑performance, multi‑layer pipe designed to deliver exceptional durability, dimensional stability, and efficient heat transfer in modern underfloor heating systems. Manufactured using a PEX‑AL‑PEX composite construction, it combines the flexibility of cross‑linked polyethylene with the strength and oxygen‑barrier protection of an aluminium core.

Purpose‑engineered for compatibility with Grant Uflex underfloor heating systems, the aluminium layer significantly reduces thermal expansion and provides excellent shape retention during installation. This allows for accurate pipe layout while maintaining consistent long‑term performance and system efficiency.

Supplied in a 250‑metre continuous coil, this pipe is ideal for larger heating areas and multi‑zone installations, helping to minimise joints, speed up installation, and improve overall system reliability in both new‑build and retrofit projects.
