This is how insulated windows work. Low-E Glass refers to the glass itself and more specifically to the outer layer of that glass. More accurately, it measures the amount of thermal energy that the outer layer of the glass puts out. We are talking "radiant thermal energy" here. People love to install low-e glass in both their places of business and in their homes primarily because of it's ability to resist ultraviolet light. Low-E windows resists UV rays which ends up protecting the valuable furnishings in homes and businesses.
Then, we consider glass that wears the "Energy Star" label. Let's break this category down into 2 sub-categories, specifically U-value glass and R-value glass. Why 2 different values? Well, it depends on the manufacturer of the glass in question. U value glass is focused on heat gain and loss as compared to the difference in outdoor or indooor temperature. However, R Value glass is all about the overall opposition to heat transference.
