Transparent thermal insulation coatings for energy efficient glass windows and curtain walls
Highlights The transparent heat insulation coatings have a high visible light transmittance. The coatings have a high near infrared absorptance and a low far infrared emittance. The coatings are electrical insulators and do not shield radio waves. The coatings have good artificial accelerated weathering resistance.
Abstract Single layer, waterborne, transparent heat insulation coatings for use in energy efficient glazing products were prepared, and their optical, thermal, electrical and artificial accelerated weathering properties were systematically investigated. The coatings combine a high transmittance in the visible region, a low transmittance (a high absorptance) in the near infrared region, a low emittance in the far infrared region, low haze and a high transmission of radio waves. While the coatings’ spectral and overall transmittances and reflectances decrease with increasing weight content of antimony doped tin oxides (ATO), their near infrared absorption, and consequently their thermal insulation, increases with increasing ATO concentration. The transparent thermal insulation coatings are electrical insulators and thus have a high transmission of radio waves. The transparent thermal insulation coatings possess good artificial accelerated weathering resistance.
