  • Coated articles and methods of making same
    Patent number: 9765423
    Abstract: A coated substrate. The coated substrate includes a unitary substrate having a major surface. A first coating is applied to a first surface segment of the major surface. A second coating applied to a second surface segment of the major surface. The first coating is different than the second coating.
    Type: Grant
    Filed: March 5, 2015
    Date of Patent: September 19, 2017
    Assignee: APOGEE ENTERPRISES, INC.
    Inventors: Russell Huffer, Randy Leland Stull, Henry Boyum, Keith Grubb, Kristin Sumner

  • Low emissivity coating with low solar heat gain coefficient, enhanced chemical and mechanical properties and method of making the same
    Patent number: 9067822
    Abstract: The invention provides low-emissivity stacks being characterized by a low solar heat gain coefficient (SHGC), enhanced aesthetics, mechanical and chemical durability, and a tolerance for tempering or heat strengthening. The invention moreover provides low-emissivity coatings comprising, in order outward from the substrate a first dielectric layer; a first nucleation layer; a first Ag layer; a first barrier layer; a second dielectric layer; a second nucleation layer; a second Ag layer; a second barrier layer; a third dielectric layer; and optionally, a topcoat layer, and methods for depositing such coatings on substrates.
