An easily stackable, heat-radiant, self-supported, rigid, high-pressure, decorative paper base laminate panel having numerous applications is disclosed. The panel comprises a heat-radiant porous fabric including electrically conductive strips. The fabric is sandwiched between sheets of paper which have been impregnated with suitable thermosetting resins as to form a unitary decorative panel upon heat-pressing. However, the sheets next to the fabric are treated with an excess of resin. The thickness and the distribution of the papers in the laminate are all important. When a suitable voltage is applied through the conductive strips the decorative panel radiates heat. Knowledge of paper laminates can aid in their conservation.
