Glazing for transmitting solar radiation

摘要

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 .
