In radiant floor heating, what is provided along with the radiant piping?

In radiant floor heating, an insulation barrier is typically provided along with the radiant piping. This insulation is crucial because it minimizes heat loss downwards into the subfloor and ensures that the heat generated by the water circulating through the pipes is effectively delivered upwards into the living space. This helps to optimize the efficiency of the heating system and maintains comfort within the room.

While the other options provide terminology that could relate to various aspects of heating systems, insulation barriers are specifically designed for radiant heating to enhance system performance by reflecting heat into the room rather than allowing it to be lost below the floor. This ensures that the system operates at maximum efficiency and provides the desired comfort levels.
