What you should know about window gas fills with windows
Help plug those thermal holes in your home.
Need to fill those thermal holes in your heating or cooling bill? Read on and hopefully we can convey our expert knowledge in this area to you!
What is it?:
So, someone may ask. "What are gas fills?" To improve thermal insulation gas is pumped in-between the panes of a window unit that has 2 or 3 glass panes. These gasses are usually argon and krypton and are used to displace the air that is inside the window panes. These gases both act as insulators. Argon itself is odorless and inexpensive to make. Krypton is more expensive to produce and yes, is a much better insulator and no, this krypton is not the same krypton that can defeat Super Man. In some windows both these gases are applied at once to help increase performance of insulation. Here is the official description... "Argon and krypton are odorless, colorless, non-toxic inert gases that can be used instead of air between panes of glass to increase insulation and energy efficiency.Argon is the cheaper, more readily available gas, but Krypton is a better insulator."
Benefits of using gas filled windows:
The cost savings of heat or cooling in your home as the gases keep energy from escaping from the inside and help to repel negative energy from the outside that will affect the internal temperature of your home.
Drawbacks of using gas filled windows:
All these window types will leak over time at 1 percent a year although that may still be efficient for 20 years. Here is one quote about sudden implosions of these types of windows, however this is very rare and usually with inferior types of window brands.
"One rare yet shocking consequence of argon leakage is the sudden implosion of the window. Due to molecular differences between argon and the principal components of air, nitrogen and oxygen, argon under pressure to escape a window unit may exit the seal faster than it can be replaced with air. Under this circumstance, the glass will bend inward to accommodate the gradual reduction in pressure within the window. If conditions are right, according to US Glass Magazine, “units have been reported to shatter with a bang, sometimes described as loud as a gunshot."
Do not be afraid. The above is one of the most rare occurrences of all. The chances of that happening to someone is very, very rare.
The end game:
Decreasing convection and improving energy efficiency is the game plan for argon and krypton filled windows. There are other process or methods to achieve this like films etc.. but the most efficient way once more is gas. So the choice is "do I choose argon or krypton gas for my windows?"
Well, personally I feel like this. To live in an area where summers are much hotter then krypton is the way to go. There is less energy transfer and since the suns brilliance can effect more energy transfer the more resistance the better (therefor krypton). In areas or landscapes that are more neutral or have less extreme seasons argon is the more cost effective way to go.
More energy transfer effects more gas or a stronger gas. Understanding your environment and weather for your homes area is key to this decision. Another recommended idea is to contact your local window supplier and cross reference this write up with what they know for your neighborhood.
