High Quality Content by WIKIPEDIA articles! Electrically heatable glass and windows are relatively new products, which help solve problems in the design of buildings and vehicles. The idea of heating glass is based on the use of energy-efficient low-emissive glass, which is generally simple silicate glass with a special metallic oxides coating. Low-emissive coating decreases heat loss by approximately 30%. Heatable glass can be used in all kinds of standard glazing systems, whether wood, plastic, aluminum or steel.
