This 16mm Underfloor heating Pipe PE-RT Barrier Pipe connects internal plumbing and heating pipework by efficiently and safely distributing water throughout your system. Specifically, it provides a highly durable and precise transfer of heating mediums for underfloor heating networks. Furthermore, thanks to its exceptional flexibility and integrated EVOH oxygen barrier , you significantly speed up installation by ensuring excellent long-term stress resistance directly on site.

Therefore, this 16mm Underfloor heating Pipe works perfectly for underfloor heating systems, hot and cold water sanitary networks, and various heating setups for domestic, commercial, and industrial applications. Additionally, it easily handles demanding applications, smoothly operating under a maximum operating pressure of 9.28 bar for radiant floors and withstanding maximum operating temperatures reaching up to 80°C.

The 16mm Underfloor heating Pipe features a robust 3-layer construction engineered from premium LG SP980 material under an ISO 9001 quality system. Moreover, it incorporates an external Ethylene vinyl alcohol copolymer (EVOH) diffusion barrier, securely bonded to the inner PE-RT layer with a dedicated adhesive. As a result, this reliable build, compliant with DIN 4726 standards, makes it virtually impervious to gases and guarantees a 49-year lifespan for low-temperature radiant floor applications at 60°C.

Key Features & Benefits:

• 100% Oxygen Barrier (EVOH): The external EVOH layer renders the pipe virtually impervious to permeating gases. Importantly, it completely prevents oxygen from entering the system in compliance with DIN 4726, protecting your metallic components from corrosion.

• Exceptional Flexibility & Strength: The PE-RT material is extremely flexible and combines long-term stress resistance with high strength at elevated temperatures. Consequently, you achieve fast, flexible loop installation with a tight minimum bending radius of just 150mm.

• High Thermal & Pressure Stability: The product effortlessly supports Class 4 (radiant floor) installations under a maximum operating pressure of 9.28 bar. Besides that, the system exhibits excellent stability, handling water with a maximum operating temperature of 80°C.

• Low Thermal Expansion: The material’s coefficient of linear expansion is impressively low at 0.18 mm/m K. Ultimately, this effectively minimizes physical stress across the heating network caused by temperature fluctuations.

• Optimal Heat Transfer: The thermal conductivity of the pipe sits at an optimal 0.45 W/m C. For example, this allows for highly efficient and even heat distribution across your underfloor heating networks, guaranteeing maximum comfort.
