- Old Solution-Tinted
Glass
-Altered glass chemistry and color absorbs heat
-No U-factor (insulating) benefit
-Reduces Solar Heat Gain
-But also blocks Visible Light
-Reduces glare
- New Solution -
Low Solar Low Emissivity Glass
-Blocks solar heat gain better than residential tint
-Lowers U-factor to improve insulating effect
-Transmits 90% as much visible light as clear glass
-Nationally, about 40% of all windows use low-E
