  • Neutral, high performance, durable low-E glass coating system and insulating glass units made therefrom
    Patent number: 5800933
    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.
    Type: Grant
    Filed: December 27, 1996
    Date of Patent: September 1, 1998
    Assignee: Guardian Industries Corp.
    Inventors: Klaus W. Hartig, Philip J. Lingle, Steven L. Larson
  • Matchable, heat treatable, durable, IR-reflecting sputter-coated glasses and method of making same
    Patent number: 5688585
    Abstract: A sputter-coated layer system including a non-nitrided and non-oxidized nickel or nickel alloy layer located between two layers of Si.sub.3 N.sub.4 of the requisite thicknesses and used for architectural and automotive glass substrates so as to be heat treatable and have .DELTA.E characteristics sufficiently low to render the products matchable as between heat treated and non-heat treated products having the same coating thereon.
    Type: Grant
    Filed: December 14, 1995
    Date of Patent: November 18, 1997
    Assignee: Guardian Industries Corp.
    Inventors: Philip J. Lingle, Klaus W. Hartig, Steven L. Larson
  • Dual silver layer Low-E glass coating system and insulating glass units made therefrom
    Patent number: 5557462
    Abstract: A sputter-coated glass layer system particularly useful in insulating glass units ("IGs"), which includes dual layers of silver separated by a layer of Si.sub.3 N.sub.4 having a thickness of about 700 .ANG.-1,100 .ANG. and further including an undercoat and an overcoat of Si.sub.3 N.sub.4 having thicknesses of about 300 .ANG.-550 .ANG. and about 350 .ANG.-700 .ANG. respectively, such that a glass so coated achieves normal emissivity values (E.sub.n 's) of less than about 0.02-0.09 with good durability and very low reflectance.

  • Low-E glass coating system and insulating glass units made therefrom
    Patent number: 5514476
    Abstract: A sputter-coated glass layer system particularly useful in insulating glass units ("IGs"), which includes a single layer of silver having a thickness of about 115 .ANG. -190 .ANG. located between two layers of nickel or nichrome having a thickness of 7 .ANG. or less, and provided with an undercoat and an overcoat of Si.sub.3 N.sub.4 having thicknesses of about 450 .ANG.-600 .ANG. and about 580 .ANG.-800 .ANG. respectively, such that a glass so coated achieves normal emissivity values (E.sub.n 's) of less than about 0.07 and good durability without acquiring a mirror-like and highly purple appearance.
