Electrically heated windscreens are designed to keep the glass vision area free from ice and fog, even under extremely cold conditions. This allows the user to enjoy clear visibility with no scraping or waiting required. Even in temperatures as cold as -10°C, heated windscreens can remove ice and mist in less than five minutes.

Electrically heated glass consists of 2 or more layers of solid tempered safety glass sandwiching PVB and a heating element. The heating element can be either an oxide film or more commonly resistive wire. The resistive wire is micro-fine tungsten wire arranged in the vinyl interlayer in a sinusoidal form (wave). The electrically charged wire creates a heated surface able to de-mist or de-ice in the most severe conditions. The glass surface can reach as high as 130 degrees Fahrenheit.

Electrically heated windows can be adapted to the special requirements as demanded by the market. 75 watts per square foot (7 to 8 watts per DM2) is the most common heating capacity. 16 watts per DM2 (150 watts per square foot) is also common on vessels such as icebreakers and coast guard ships. Anything exceeding 8 watts requires a thermostatic control. Heated glass for off road or rail vehicles can be offered in lower voltage requirements such as 12V DC. Glass composition is similar to marine application except chemically toughened glass is used in some cases.
