Abstract
Low emissivity panels can include a separation layer of Zn2SnOx between multiple infrared reflective stacks. The low emissivity panels can also include NiNbTiOx as barrier layer. The low emissivity panels have high light to solar gain, color neutral, together with similar observable color before and after a heat treatment process.
