You probably know that you can reduce the cost of heating and cooling your home by replacing the “regular” windows in your home with windows that have been engineered to be more energy efficient. But did you know that one of the most important “parts” that makes a window energy efficient is a colorless, odorless gas?
Older windows were usually made with a single layer of glass. But today’s high performance replacement windows are designed with at least two, and sometimes three panes in a glass “sandwich.” It is this sandwich effect that helps to significantly slow down heat transfer, keeping your home warmer in winter and cooler in summer.
But the glass alone can’t do the job. The narrow spaces between the panes of glass do their part, too. If these slim pockets were filled with regular air they would not help to slow down heat transfer. So window designers fill the gaps between glass panes with inert gas, usually either krypton or argon.
Inert gases like argon and krypton are used because they are non-toxic, clear, odorless and chemically non-reactive. These gases have a higher density than air. This gives them insulation properties that, added to the additional pane or panes of glass, greatly enhance the thermal performance of a window.
There is one more important component to consider. The glass panels are kept separated by a “spacer” that is traditionally made of metal, such as aluminum. But metal spacers defeat the purpose of window insulation by serving as a conductor of heat. So the best replacement windows now use “warm spacers” made of materials that do not conduct heat like a metal spacer.
While this may all seem like weird science, these are the specific features you should look for in order to ensure that the replacement windows you purchase will do the best job of keeping your home and family safe and warm this winter.
