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.
