Abstract
The invention is directed to a radiant heat ceiling panel which operates at low temperature and transmits heat directly by radiation. The basic panel structure consists of a fibrous heating element covered on both sides with polyester sheets and backed by a rigid fiberglass backing and faced with a decorative layer which serves as the heat radiating surface. Most of the elements of the heating panel are made of materials or nearly equal coefficients of expansion. The complete panel is mounted in a frame with an edge raised above the surface of the decorative layer.
