Abstract

An architectural transparency includes a substrate; a first dielectric layer over at least a portion of the substrate, a first metallic layer over the first dielectric layer, a first primer layer over the first metallic layer, a second dielectric layer over the first primer layer, a second metallic layer over the second dielectric layer, a second primer layer over the second metallic layer, a third dielectric layer over the second primer layer, a third metallic layer over the third dielectric layer, a third primer layer over the third dielectric layer, and a fourth dielectric layer over the third primer layer. At least one of the metallic layers is a subcritical metallic layer.
