Abstract
An architectural glass for use in a greenhouse comprising a substrate having a coating, the coating comprising a first dielectric layer, a metal layer over the first dielectric layer, a second dielectric layer over the metal layer, and a first protective overcoat over the second dielectric layer, wherein the first protective overcoat comprises silica and alumina. A back surface of the glass substrate can be coated with a scattering layer and a second protective overcoat. The architectural glass can be a monolithic glass or a component in an insulated glass unit. A method of increasing photosynthesis efficiencies in an insulated glass unit to greater than 88%, greater than 90%, or greater than 93% is also disclosed.

An architectural glass for use in a greenhouse comprising a substrate having a coating, the coating comprising a first dielectric layer, a metal layer over the first dielectric layer, a second dielectric layer over the metal layer, and a first protective overcoat over the second dielectric layer, wherein the first protective overcoat comprises silica and alumina.
An architectural insulated glass unit comprising:
- a first substrate having a No. 1 surface and a No. 2 surface;
- a second substrate having a No. 3 surface and a No. 4 surface, wherein the second substrate is spaced from the first substrate, and wherein the first and second substrate are associated with each other to define gap therebetween, wherein the No. 2 surface and the No. 3 surface are oppositely disposed from each other and define the gap between the first substrate and the second substrate;
- a coating located on the No. 2 surface, the No. 3 surface, or the No. 4 surface, the coating comprising a first dielectric layer, a metal layer over the first dielectric layer, a second dielectric layer over the metal layer, and a first protective overcoat over the second dielectric layer, wherein the first protective overcoat comprises silica and alumina.
A method of increasing photosynthesis efficiencies in an insulated glass unit for use in a greenhouse comprising;
- passing sunlight through an architectural glass comprising a substrate and a coating over at least a portion of the substrate, wherein the coating comprises a first dielectric layer, a metal layer over the first dielectric layer, a second dielectric layer over the metal layer, and a protective overcoat over the second dielectric layer, wherein the first protective overcoat comprises silica and alumina.
