WIPO Patent Application WO2003050056
Kind Code:
A8
Abstract:
A self-cleaning glazing sheet, preferably of glass, comprises a substrate, a hydrophilic coating on a surface of the substrate, and heating means for raising the temperature of the self-cleaning glazing sheet above the temperature of a self-cleaning glazing sheet having no heating means. Preferably, the hydrophilic coating is photocatalytically active, most preferably of titanium oxide. The preferred heating means comprises a tinted glass substrate which can use incident radiant energy to raise the temperature of the substrate. Multiple glazing units and laminates comprising a self-cleaning glazing sheet and heating means are also disclosed.
