A gas fill is an important feature of any energy-efficient window. This component is used in double glazing technology, a window design that uses two panes instead of one. A gas fill also complements the thermal performance of Low-E coatings, ultra-thin metallic layers that reduce heat transfer.
Manufacturers have used different gas fills over the years, but one of the more popular ones is argon. Today, Stittsville Windows and Doors explains why the best replacement windows use argon gas fills.
1. Energy Efficiency
As an inert gas, argon is an excellent insulator. Compared to air, argon is six times heavier. Its superior density makes it hard for thermal energy to pass through it, resulting in a significant reduction in heat loss.
2. Condensation Resistance
Argon contributes to a window’s condensation resistance, too. This gas’s effectiveness at preventing the heat inside a home from escaping allows it to keep the window glass temperature constant. If a pane is warm enough, it may not reach the dew point, which is the level of temperature where water vapor turns into liquid. This is why you don’t see a cup of coffee sweat like a bottle of cold water in the summer.
3. Noise Abatement
As an insulator, this gas dramatically reduces the transfer of not only heat but also sound. When closed, argon-filled vinyl and wood replacement windows block the noise pollution from the outside, making your home much quieter.
4. Cost Effectiveness
Many manufacturers use argon to reconcile affordability with performance to drive down window costs without sacrificing energy efficiency.
Another practical advantage of argon is it doesn’t compromise the structural integrity of the rest of the unit. It doesn’t accelerate the corrosion of any window material like oxygen does. Freon and carbon dioxide were also used for fill but proved to cause discoloration in the event of seal failure.
Most importantly, argon is a non-toxic gas, making it safe to breathe in the event of leakage. While it could be a health concern when inhaled in an enclosed space, the small amount of this gas used in dual-pane window production shouldn’t cause any harm.
