Abstract
Dual coated glass sheets comprise a photocatalytically active self cleaning coating on one surface and heat reflecting coating on the second surface selected so that its single surface reflectivity is either at least three times or less than one third that of the self cleaning coating. The selection of the heat reflecting coating provides a sheet having an improved appearance. Such dual coated sheets combine self cleaning properties with solar control or low emissivity properties and are useful as building glasses.
