You may have heard people talking about argon and krypton gas when discussing replacement windows lately. When these mentions of gas and windows come up do you scratch your head and reply "I didn't windows had gas!"?
It's a fairly new feature that replacement windows have nowadays to include some kind of slow moving gas in the space between the two panes in a modern replacement window. And though now it has become common to find on almost any vinyl window these days, questions still arise as to why people are even talking about gas when referring to their windows.
Let's start with argon gas. Almost any double paned replacement window on the market will have this gas as a standard feature. Along with low-e, argon gas is pretty much a non-issue when selecting a vinyl replacement double hung window because every insulated window has it. But what is argon gas, what does it do, and why should you make sure your window have it?
Argon is a very dense, slow moving, inert gas. The reason it is pumped in between the panes of replacement windows is because of its unique ability to slow down heat from entering into your home. It works along with the low-e coating replacement windows have to keep a high insulation value in your home (measured by U-values and R-values). Typically, a replacement window with argon gas and low-e will have a U-value somewhere around .25 to .30 (remember, the lower the better!). Again, argon gas is standard in most replacement windows and if it's not included as part of the insulation package it's not worth looking into.
Now there's also Krypton gas. No, Superman has nothing to do with this one. Much like its cousin argon, Krypton is an odorless, tasteless, invisible gas that is used for its inert, dense qualities. However, Krypton is much denser and has better insulation qualities than argon. Krypton is not typically offered as a standard item in insulated glass packages and with most windows is an upgraded or added option. Many vinyl window manufacturers offer Krypton gas as an option or even a krypton and argon blend for a better insulation value.
Typically, adding Krypton or a Krypton/Argon blend will provide your glass with a .16 to .10 U value (don't forget less is more).
There you have it. A little crash course in krypton and argon gas and why you should be sure it's a part of any replacement window you install in your home.
