MATCHABLE LOW-E I.G. UNITS AND LAMINATES AND METHODS OF MAKING SAME

摘要

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 DELTA E*ab is less than about 3.0 and DELTA 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.
