John Guest Speedfit PEX (Cross-Linked Polyethylene, an alternative to plastic and copper for home plumbing) barrier pipes are lightweight and flexible, making them perfect for underfloor heating installations. Thanks to their low thermal conductivity, these pipes are cooler and safer to touch when carrying hot water. They feature an inner barrier which prevents the flow of air.
