WIPO Patent Application WO/2019/112320

A1

Provided is a functional building material for windows and doors, the material comprising a transparent substrate and a low-emissivity coating formed on one side of the transparent substrate, wherein: the low-emissivity coating comprises a first dielectric layer, a second dielectric layer, a lower barrier layer, a third dielectric layer, a first low-emissivity protection layer, a low-emissivity layer, a second low-emissivity protection layer, a fourth dielectric layer, a fifth dielectric layer, an upper barrier layer, and a sixth dielectric layer which are laminated in that order on the transparent substrate; the refractive index of the first dielectric layer and the refractive index of the third dielectric layer are each smaller than the refractive index of the second dielectric layer; and the refractive index of the fourth dielectric layer and the refractive index of the sixth dielectric layer are each smaller than the refractive index of the fifth dielectric layer.
