Nano-silica cryogels and ATO composite dispersion were coated on PET film, and then the coated film was pasted on the glass to prepare filmed glass. The optical and thermal insulation properties of the filmed glass were investigated. The results showed that the filmed glass with dispersion of 10%SiO2 + 10%ATO had better spectral selectivity. The visible light transmittance, near-infrared shielding wavelength (with transmittance less than 10%) and shading coefficient of the filmed glass were 77.2%, 1500 nm and 0.69 respectively. It also showed good heat-insulating performance. The air temperature inside the test box with filmed glass was 8oC lower than that with blank glass.
