- ItemProtection against heat, radiation and glare - New developments in automotive glazings(Offenbach : Verlag der Deutschen Glastechnischen Gesellschaft, 1994) Weigt, Paul; Schrey, HelmutTo maintain thermal comfort for driver and passengers in cars body-tinted, coated and insulated glasses were recently developed. Representative glasses of these categories and their thermal properties are presented. For assessment o f the sun-protective properties the spectrophotometric data are taken into account. The use of these glasses with respect to the legal Hght transmittance limits is discussed. The presentation of the heat protection function includes the determination of U values for different driving conditions. The determination of the spectrophotometric and heat engineering data with respect to the International Standard ISO/DIS 9050 is discussed. I t is shown, how far deviations from this standard can lead to misleading evaluations of the same glazings.
