The invention moreover provides low-emissivity coatings comprising, in order outward from the substrate a first dielectric layer; a first Ag layer; a first barrier layer; a first absorbing layer; a second dielectric layer; a second Ag layer; a second absorbing layer; a third dielectric layer; and optionally, a topcoat layer, and methods for depositing such coatings on substrates.10/11 TOPCOAT (OPTIONAL) DIELECTRIC ABSORBING Ag NUCLEATION DIELECTRIC ABSORBING BARRIER Ag NUCLEATION DIELECTRIC SUBSTRATE FIG. 9
