ClimaTech® Your solution performance.

The optional ClimaTech Insulated Glass Package combines PPG's Solarban® 60 multi-layered Low-E Glass with the Intercept™ Warm Edge Spacer System and argon gas. The ClimaTech glass package is up to 40% more energy efficient than most other low-E or mid-E glass systems, and provides more than twice the energy efficiency of clear glass units. Excalibur Windows with ClimaTech far exceed the performance requirements set forth by the US Department of Energy in conjunction with the National Fenestration Rating Council (NFRC) test criteria. One of the most critical NFRC tests measures the rate of heat loss through a window or door (U-Value). The lower the U-Value, the better the product is at resist­ing heat flow, which results m a product with a greater insulating value.

Another critical NFRC test is for Solar Heat Gain Coefficient (SHGC). This procedure measures how well a product blocks heat caused by sunlight. Again, the lower the number, the less solar heat the window transmits into the home. Both charts clearly show how the performance of Excalibur Windows can be enhanced with the addition of the ClimaTech Insulated Glass Package.
