Abstract
The invention relates to a silver low-E coating for glass which is temperable and can be applied by means of sputter processes onto the glass. The individual layers of the coating are cost-effective standard materials. One embodiment of the invention for example is comprised of a glass substrate, an Si3N4 layer disposed thereon of a thickness of approximately 15 nm, a TiO2 layer of 15 nm thickness on the Si3N4 layer, a 12.5 nm thick Ag layer on the TiO2 layer, a NiCrOx layer of approximately 5 nm thickness on the Ag layer and a terminating 45 nm thick Si3N4 layer.
