Abstract
A glazing unit permitting collection of an increased amount of incident solar energy and composed of a substrate of a composition such that its total solar radiation energy transmittance is greater than that of a similarly dimensioned substrate of ordinary soda-lime glass, and a coating at least partially covering at least one face of the substrate and being at least partially reflective of infrared radiation having a wavelength greater than 3.mu..
Claims18
A glazing unit comprising, in combination:
- a soda-lime glass substrate having a composition such that its total energy transmittance for solar radiation is greater than that of a similarly dimensioned substrate of ordinary soda-lime glass which contains ferrous oxide, said substrate having a composition which contains iron oxide with substantially all of said iron oxide being ferric oxide, and a metal oxide coating of a composition which transmits solar radiation and at least partially reflects infrared radiation having wavelengths greater than 3.mu. at least partially covering at least one face of said substrate.
