Abstract
The invention provides low-emissivity stacks comprising at least one absorbing layer, said 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 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.
