Flexalen U-Values (EN)

This technical document outlines the U-values, or thermal transmittance, for the Flexalen pre-insulated PB piping system. It includes calculations based on European standards EN15632 for flexible heating pipe systems and EN 12828 for heating systems in insulations. The document provides detailed U-values for various service and casing pipe diameters, highlighting insulation classes and heat transfer to soil parameters. It serves as a comprehensive guide for understanding the thermal efficiency of Flexalen piping systems.
