Abstract
A low-E sputter-coated layer system for automotive and architectural purposes of the basic Si.sub.3 N.sub.4 /NiCr/Ag/NiCr/Si.sub.3 N.sub.4 type improved by either an undercoat of TiO.sub.2 or the use of stainless steel in the Si.sub.3 N.sub.4 layers, or both. By selection of appropriate thicknesses the layer coatings may be rendered heat treatable. I.G. units are an advantage product in which the coatings may be employed.
