E-GLAS: active insulating glazing with radiant heat control.  Electronically-controlled low-emissivity coating converts electrical power into heat. Depending on its composition, it can direct heat outward or inward to: melt falling snow, prevent condensation, or constitute a source of heat.


Applications include: Glass roofs, verandas, winter gardens, display cases and picture windows; pools, spas, saunas, bathrooms and other humid areas; lobbies, atriums, and all types of interior concourses in residences, hotels, offices, shopping malls, airports, cultural and sports centers, ships…


Technology: The “heating” surface of the double or triple glazing is low-emissivity glass: when stimulated by electrodes, tin oxide thinly coated over the inner face, on the side of the vacuum (filled with Argon), radiates heat toward the opposite face.
