The present invention provides a low emissivity laminate structure, characterized in that the laminate structure has a low solar gain coefficient (SHGC), improved aesthetics, mechanical and chemical durability, and resistance to tempering or heat strengthening. The invention also relates to a first dielectric layer in order from the substrate to the outer side; A first crystal nucleation layer; A first Ag layer; A first barrier layer; A second dielectric layer; A second crystal nucleation layer; A second Ag layer; A second barrier layer; Third dielectric layer; And optionally a low emissivity coating comprising a topcoat layer, and a method of depositing such a coating on a substrate. |
