Claim:
1. An architectural transparency, which is non-tempered, comprising: a) a first ply, comprising: an annealed glass substrate; and a coating stack over at least a portion of the substrate, the coating stack comprising: a first dielectric layer; a first continuous metal layer over at least a portion of the first dielectric layer; a first primer layer over the first continuous metal layer; a second dielectric layer over at least a portion of the first primer layer; a second discontinuous metal layer over at least a portion of the second dielectric layer; a second primer layer over at least a portion of the second discontinuous metal layer, wherein the second primer layer comprises titania; a third dielectric layer over at least a portion of the second primer layer; a third continuous metal layer over at least a portion of the third dielectric layer; a third primer layer over at least a portion of the third continuous metal layer; and an outermost protective coating over at least a portion of the third primer layer, wherein the protective coating comprises titania having a thickness in the range of 4 nm to 6 nm; b) a second, transparent or translucent ply; c) a spacer frame spacing the first ply and the second ply apart, the first ply, the second ply, and the spacer frame defining a chamber; and d) a gas within the chamber.
