Radiant Ceiling Panel Systems consists of a high-density fiberglass insulation board, a solid-state heating element and a textured surface coating mounted in a frame. The panels are usually 1-inch thick, range in size between 1 x 2 & 4 x 8 feet and are powered by 120 or 240-volt household electrical current. Panels typically operate at a temperature range of 150 to 170°F. Radiant ceiling panels rapidly change a rooms environment and heat quickly when turned on & cool quickly when turned off. Radiant panel ceiling systems are an energy and cost saving method of heating & cooling. The radiant ceiling panels are used to heat and cool the perimeter spaces. These systems are used in commercial buildings.
