Abstract

A neutral blue-green heat treatable and matchable glass laminate or I.G. unit employs a layer system whose visible transmittance increases by at least 4% during heat treatment and whose &Dgr;E*ab is less than about 3.0 and &Dgr;a* is less than about 0.7. The sputter coated layer system includes a silver layer sandwiched between nichrome layers and thereafter layers of Si3N4.
