Heating wire / safety glass
Luma Tungsten wire as heating wire in windshields, in for example cars, ships and trucks, has a long history. The technology is based on running current through the wires, creating heat. The heat melts snow and ice and it removes vapour. This type of laminated glass can also be used in skylights and glass roof constructions, acting as a safety melting snow or making sure that the glass is clear; free from frost or ice.
Tungsten wire is also used in glazed surfaces such as penthouses, hotels, conference facilities and cruise ships. These glazed surfaces can go from clear to tinted, without losing view from the inside. Thin, almost invisible, wires are used. By adding low current into the wires, it controls an oxidation reduction which creates a dark shade. When deactivating the current the surface returns to being clear.
