Today, many replacement windows include argon gas as an insulating material which is filled in between the panes of a window. Adding argon gas in replacement windows increases the overall efficiency of your home.
Technically speaking, argon gas is an odorless, colorless, invisible noble gas that occurs naturally in the atmosphere. It is non-toxic, nonflammable, and completely safe. This is an inert gas, meaning it doesn’t form true chemical compounds as opposed to other noble gasses (krypton, neon, xenon and helium).
In addition to improving the thermal performance of replacement windows by reducing heat transfer between the panes, argon is also used in radio tubes, gas-filled electric bulbs and in production of metals such as zirconium, uranium and titanium.
Originally, the space between the window panes was filled with dry air or nitrogen. The panes were airtight in the window sash. The double-panes or triple panes provided a form of insulation. Nevertheless, this method proved ineffective as air currents in the panes pushed any heat to the top of the unit, leaving cold air at the bottom. But argon gas is a slower-moving and less conductive gas. When pumped between the double or triple panes, it reduces conduction and lowers the convection currents through the glass.
Argon windows are super-efficient because it is a heavy gas (about 195% heavier than air). Thus, argon gas is better at retaining heat in your home during the long winter months and keeping cool air in during the warmer months.
Argon-filled filled are becoming a more and more popular choice for many homeowners due to several reasons. The following are a few benefits of installing argon-filled windows in your home. Number one, windows filled with argon gas will increase the thermal transmission or U-Value of your windows. The rate of heat transfer is usually measured by what is known as U-Value. The lower the U-Value of a window, the lower the rate of heat transfers through that window. Number two, argon gas can help in limiting condensation in your windows. Number three, it will improve the soundproofing features of your house as well as ensuring the working efficiency of your heating and cooling systems.
