· Solar-Control Tinted Glass
Solar-control tinted glass can be used in a single-pane application or an insulating glass unit application. All tinted glasses provide some degree of glare control and provide a faint color appearance. Tinted glasses typically block the solar energy by absorbing the solar heat and re-radiating it outside as well as inside. When used in an insulating glass unit (with the tinted glass glazed to the outside), most of the heat re-radiated towards the inside is captured in the airspace and not transmitted to the interior of the home.
Tinted glasses available from PPG in residential thicknesses include Solarbronze ®, Solargray ®, Graylite ®, Solexia™ (formerly Solex ®), Azuria™ (formerly Azurlite ®), and Atlantica™ (formerly Solargreen ®). All of these tinted glasses can be combined with a PPG Low-E glass product to construct a higher performance insulating glass unit.
· Solar-Control Low-E Glass
Solar-control low-e glass must be used in an insulating glass unit. In addition to blocking more of the direct solar energy, it also improves thermal insulation (lower insulating glass unit u-values), which helps keep cool air inside and hot air outside.
Solarban ® 60 is a solar control low-e glass from PPG.
