What type of framing must heating panels be secured to?

Heating panels are designed to be mounted securely to framing that provides adequate support and stability. The correct choice specifies wood or steel, both of which are common materials in construction that can bear the weight of heating panels and withstand the thermal variations they produce.

Wood framing is widely used due to its availability, ease of installation, and compatibility with most building designs. When secured to wood, the heating panels can be easily installed and maintained. Steel framing also offers a strong and durable solution, particularly in commercial applications where larger spans and greater strength are required.

This choice ensures that the heating panels are attached to materials that can handle their weight and any thermal expansion that may occur during operation, reducing the risk of damage or malfunction. In contrast, the other materials listed either lack the necessary structural integrity (like plastic or fiberglass) or are not typically associated with universal framing practices for heating panels (such as brick or stone, which are generally not used for mounting panels due to their lack of flexibility and adaptability in installation).
