 How can LoE² Glass Glazing Technology make me more comfortable? First, you need to understand what is meant by U-value and R-value, the primary terms the industry uses to describe the energy performance of windows. U-VALUE is the rate at which heat flows through a window from indoors to outdoors...call it heat loss. R-VALUE is the thermal resistance of the glass to that heat loss. The higher the R-Value, the higher the energy savings. Comfort is related to indoor glass surface temperature. The closer the glass surface temperature is to normal room conditions (70°F), the more comfortable a person will feel. So both indoor glass surface temperature and personal comfort are dependent upon the U-Value of the glass. Winter nighttime conditions with no sun shining on the window are considered worst case conditions for heat loss, so this situation is used as a benchmark for performance.  The lower the U-Value, the higher the energy savings. LoE² GLASS IS BENEFICIAL BECAUSE IT PROVIDES HIGHER WINTER NIGHTIME GLASS TEMPERATURES. Add the fact that our LoE² GLASS INCREASES R-VALUE BY 96% and you have a window that is warmer both at the edges and across the entire glass area.LoE² glass can help you save as much as $577 a year on energy costs.* The map below outlines the average potential savings possible in zones across the United States. |
