New 3-layer near-infrared reflective glasses were prepared by coating clear float soda-lime glass with nanostructured TiO2 and SiO2 films using a dip coating technique. Reflective interference filters at NIR region (800-1000 nm) were designed by simulation and prepared onto 4 mm clear glass. Optical, microstructural and mechanical properties were determined for the coated glasses. 3-layer sol-gel glasses show high visible transmittance >70% combined with high solar reflectance about 30% (with reflectivity up to 60% at region from 800 to 950 nm) and high UV blockage (transmittance <35%). Due to good abrasion resistance of the filters, application for monolithic windows in automotive and architectural areas is promising. © 2011 Elsevier B.V. All rights reserved.
