We Have Gas Filled Windows
Our windows have gas. Insert joke after joke … I did. And I found myself giggling like my 9 year old boy. I was having so much pun with gas innuendos. Then my editors armed with red pens and a ridiculous propensity for the appropriate, expeditiously “axed” my eloquent exploitation. So now that the gas jokes Argon. Let’s delve into another component of our high performing European windows.
Gas Filled Windows
To assist in obtaining higher levels of performance, our insulated glazing units or IGU’s are filled with inert gas. Our gas filled windows typically use Argon gas because it is heavier than air, improving the performance over simple air fills. This viscous, slow-moving gas allows for less convection than ordinary air, minimizing convective currents within the IGU and reducing heat transfer through the window. This improves energy efficiency and performance of the window.
Argon is a chemical element with the symbol Ar and its atomic number is 18. It is the 3rd most common gas in the atmosphere. A noble gas, Argon which comprises less than 1% of the Earth’s atmosphere, is non-toxic, inert, clear and odorless. Its thermal conductivity is roughly 67% that of air and it is not expensive, making it an attractive gas fill. Argon tends to be more effective in spaces about ½” gap.
Occasionally when the application calls for it we use another viscous, slow moving gas – Krypton. Krypton is a chemical element with the symbol Kr and its atomic number is 36. Krypton shares many qualities with Argon, except it is an even better insulator. Krypton occurs in trace amounts within the earth’s atmosphere making it more expensive than Argon. Krypton tends to be more effective in narrower spaces ¼”-3/8” gap.
These gases and warm edge spacers, thermal breaks, low iron glass and low-e coatings are some of the components of our energy efficient windows and doors. Our gas filled windows provide comfort and humor throughout the year.
Ps. I had a gas writing this blog post.
