Heated glass is a resistance heater created when a transparent, electrically conductive coating is applied to float glass and then subjected to an electric current.
The electrical current in the surface-coating creates heat energy, which warms the glass until the glass radiates heat.
Heated glass has been used in architectural applications for the past 30 years to prevent condensation and provide radiant heat to a room. Heated glass is generally an enhanced standard two-pane insulated glass window using various bus bar technologies to convey the electric current to heat the glass.
Heated glass systems can be used as the primary system of heating or combined with floor heating and ceiling heating.
