A hearth panel includes an edge member defining a geometric shape, such as a continuous loop, and two (or more) non-combustible panels with perimeters contained inside the edge member, and with the panels defining an air gap therebetween, thus providing an R value of over 2.0 and as high as 3.5 or more. Spacers in the air gap help prevent drooping of the panels. Tile is attached to the top panel for aesthetics. In some versions, the edge member includes a flange forming the gap's thickness. In some versions, the edge member is roll formed from constant thickness sheet, or extruded from an extrudable material such as aluminum. |
