US Patent 11707918 Radiant panel

A radiant panel includes a surface layer that is thermally conductive and includes exterior and interior surfaces. A first interior layer is electrically conductive and includes exterior and interior surfaces. The exterior surface of the first interior layer and the interior surface of the surface layer are coupled to one another. A second interior layer includes thermally insulative properties and a first rigidity. The second interior layer includes exterior and interior surfaces. The exterior surface of the second interior layer and the interior surface of the first interior layer are coupled to one another. A third interior layer includes thermally insulative properties and a second rigidity. The third interior layer includes exterior and interior surfaces. The exterior surface of the third interior layer and the interior surface of the second interior layer are coupled to one another. The second rigidity is greater than the first rigidity.
