Abstract
A solar-control transparent substrate composition is presented having a transparent substrate, a multi-layer stack and a low emissivity layer thereon. The multi-layer stack comprises at least three sub-layers with at least one sub-layer being a near infrared solar absorbing layer and at least one sub-layer being a low refractive index layer. Also provided is a method of producing the improved, coated, solar-controlled transparent substrate. The solar-control transparent substrate composition provides an improved solar control glass with reduced haze, improved visible transmission and a more neutral reflective color.
Claims36
A coated solar control transparent substrate composition comprising the following layers:
- a) a transparent substrate;
- b) a multi-layer stack comprising at least three sub-layers, said sub-layers including at least one near infrared absorbing sub-layer having a relatively high refractive index, and at least one sub-layer having a relatively low refractive index;
- and
- c) a low emissivity layer.
A process for producing a coated solar control transparent substrate composition comprising sequentially depositing on a transparent substrate:
- a) a multi-layer stack comprising at least three sub-layers, said sub-layers including at least one solar heat absorbing sub-layer having a relatively high refractive index, and at least one sub-layer having a relatively low refractive index;
- and
- b) a low emissivity layer.
