Low-E Glass
Features and Benefits of Triple-Pane IGU’s containing a Low-E coating:
Warmer in Winter
The winter nighttime U-Value (insulating value) of a Sungate 400 (5) triple-pane glass unit (IGU) is 38% better than a tripled-glazed IGU with standard clear glass. The winter nighttime U-Value (insulating value) of a Solarban 60 (2) triple-pane glass unit (IGU) insulates 42% better than a tripled-glazed IGU with standard clear glass.
Cooler in Summer
The total solar energy transmitted through a clear, triple-glazed IGU with Solarban 60 (2) glass is 47% less than that transmitted by a triple-glazed IGU with standard clear glass.
Transmits Daylight
Triple-glazed IGUs with Sungate 400 (5) transmit about 96% of visible light as standard clear insulating glass. Triple-glazed IGUs with Solarban 60 (2) glass transmit about 89% of the visible light transmitted by a triple-glazed IGU with standard clear glass.
Fading Factors
While Sungate 400 (5) glass blocks 73% of damaging UV energy, it also blocks other contributors to fading – in all, 12% better than standard clear insulating glass. While a triple-glazed IGU with Solarban 60 (2) glass blocks about 83% of damaging UV energy, it also blocks other contributors to fading – in all, about 24% better than a triple-glazed IGU with standard clear glass.
