12mm PE-RT EVOH Underfloor Heating Pipe – 3-Layer Barrier Pipe for UFH Systems

The 12mm PE-RT EVOH Barrier Pipe is a flexible, durable, and installer-friendly pipe, purpose-built for underfloor heating systems. Manufactured using three-layer PE-RT technology, it includes an EVOH oxygen barrier that prevents corrosion within heating circuits, extending the life of the entire system.

This pipe is lightweight, easy to bend, and allows for tight-radius curves without the need for fittings—making installation quick, clean, and efficient, even in tight spaces.

Frequently Asked Questions

• What is this pipe made from?

It’s made from PE-RT (Polyethylene of Raised Temperature Resistance) with a 3-layer structure.

• What is the EVOH layer for?

The EVOH barrier prevents oxygen from entering the heating system, protecting metal parts (like boilers and valves) from corrosion.

• Can this pipe be used with all underfloor heating panels?

Yes, it’s compatible with most UFH systems and is especially suited for use with clip rail, castellated, grooved board, and low-profile systems.

• Is it easy to install?

Very. It’s lightweight, flexible, and kink-resistant, making it easy to route without special tools.
