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 (FAQs):

Q1: What is this pipe made from?

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

Q2: What is the EVOH layer for?

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

Q3: Can this pipe be used with all underfloor heating panels?

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

Q4: Is it easy to install?

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