If you want to cut down on your heating and cooling costs, then there are a few different upgrades you can make to your home to help with energy efficiency. Replacing your windows is one of these things. There are a wide variety of energy efficiency windows that you can choose from, and some are created with a gas between the two window panes. However, you may not quite understand how the windows work and you might believe some myths about them. Keep reading to learn about the truth behind gas filled windows so you can make the right choice when considering windows for your home.

Myth—Gas Can Leak & Cause Health Problems

There are many types of gasses that can cause health problems if they are breathed into the lungs. Chlorine, nitrogen dioxide, carbon monoxide, and ammonia are a few examples. 

However, not all gasses are bad or harmful. In fact, we breathe in several different gasses each and every day. These gasses are the ones that make up the atmosphere: carbon dioxide, argon, oxygen, and nitrogen. Argon is the type of gas that is placed in most gas filled windows. Since you breathe in this gas every day, it is not harmful and it will cause no health problems if it leaks out of your windows. 

Argon is not the only gas that is used to create gas filled windows. Both krypton and xenon gas can fill the space between window panes as well. Sometimes krypton and xenon are mixed together to create the windows, or they are mixed with argon. These gasses are just as safe as argon. 

Myth - Windows Are Ruined When Gas Leaks Out

All windows are made with seals that help to encourage energy efficiency and the reduction of thermal gain. Double pane windows with gas inserts are sealed by the vinyl or wooden frame. Silicone is then spread around the inside edge of the frame to help keep the gas contained in the window. However, seals will deteriorate over time and frames contract when the weather changes. This can lead to the formation of leaks around the frame. 

Argon gas is a dense material that is heavier than the air in the atmosphere. The properties of the gas mean that it wants to escape and sink below some of the lighter gasses that make up the air. The gas places pressure on the window and seeps out wherever it can.

When argon gas escapes, air will enter the window and bring water vapor with it. The vapor clings to the inside of the window, and you will see the condensation on the glass. While the condensation may appear unsightly, it does not ruin the window or indicate that you need to invest in a replacement right away. 

Myth - Gas Cannot Be Replaced

If you notice that gas has leaked from one of your windows, then you may think that the gas cannot be replaced. This is simply not true. Make an appointment with your window specialist so that new gas can be inserted into the window. The professional will use a tool to see how much gas is left in the window and a probe will be inserted through the window seal to add gas to the space between the window frames. 

You will need to repair seals and frames before more gas is added to your windows. Make sure to replace sealant and to tighten any fasteners or screws around the frame. This will help to reduce future leaks and the formation of condensation. For more information, contact energy efficient window installers.
