Wood veneer radiant heating panel

Claim 1

A multiple layer wood veneer containing laminate form of heating panel comprising at least two layers of wood veneer sheeting, a plurality of wood core layers, a thermosetting adhesive forming a glue line between the plurality of layers of said panel, a filler composition of semiconductive carbonaceous pyropolymer particles less than 100 microns in size, said particles having been formed by heating an organic pyrolyzable substance in a primarily nonoxidizing atmosphere in contact with a refractory inorganic oxide material at a temperature above about 400°C. such that the resulting semiconductive composition will have a conductivity of from about 10.sup. -8 to about 10 2 inverse ohm-centimeters, said filler particles being present in particulate form in admixture with the adhesive forming a glue line between two of said core layers and in an amount of from about 10% to about 80% by weight of said adhesive, and electric current supply means to spaced apart portions of said glue line containing said particles.
