ABSTRACT:
A heating element for bathroom and similar mirrors is formed as a laminate for placing behind a conventional mirror glass. The laminate has separate foil conductor patterns forming distribution and return conductors for the supply current, and a continuous conductor layer formed by a higher resistivity conducting paint or coating extending between the conductor patterns. Preferably the conductor patterns are formed as longitudinal bands on a continuous web of insulative substrate material which is then cut into lengths which are mounted on backing sheets of appropriate size and which carry buses to establish connection between the conductor bands and an electrical supply.
