Low E Glass – Energy Savings Comparison

Savings Comparison Table

Check out these numbers below. They are going to make you a believer in Low-E Glass that has the magic heat film suspended between the panes of glass. The thing that is amazing is that the energy savings numbers represent an upgrade from standard insulating glass with argon! If you are buying new windows that have the heat film glass and are upgrading from traditional single pane glass with possibly storm windows, your savings will be even greater!

Note the interesting correlation between the highest savings and the geographic location. The highest savings appear to be in the southwest part of the nation. Keep in mind that these savings are also a function of what you have to pay to heat and cool your house. In other words, people with high electric and fuel costs will save more money on a percentage basis. So you know, these calculations were based upon a 2,100 square foot house that has a 24 percent window to floor area ratio. The calculations are courtesy of Southwall Technologies - a leader in heat film glass technology!
