For radiant piping in slab-on-grade heating applications, what should the R-value marking be?

In radiant piping applications for slab-on-grade heating, it is essential for the R-value marking to be visible. This visibility ensures that anyone inspecting the system can easily identify the insulation properties of the piping. The R-value is a measure of thermal resistance, and its visibility is critical for confirming that the installation meets the necessary building codes and energy efficiency standards. An easily readable R-value allows for better assessments of the system's performance and helps ensure compliance with industry standards.

Having the marking clearly visible helps professionals in the field recognize the materials used, which is important for maintenance, troubleshooting, and any potential future upgrades or modifications to the heating system. It is vital that those responsible for the system can quickly reference this information without having to search for hidden or obscure markings.
