Argon Gas-Filled Windows: Advantages and Applications

Argon Gas-filled Window

Reading time: 1 minute

Argon gas-filled windows consist of double or triple glass panes and argon gas that fills the space between them. The argon gas improves the durability and insulation capacity of the window. 

In addition, it does not conduct heat and prevents the buildup of frost at the bottom of the window during winters. Argon is an inexpensive, non-toxic, and odorless gaseous element that is found in the earth’s atmosphere.

What are Argon Gas-Filled Windows?

Argon gas-filled windows are manufactured from double or triple glass panes whose interface is filled with argon gas, see Figure-1 and Figure-2. The gas is driven into the window through a small hole, and air in the space is forced out through another hole, see Figure-3. These holes can be used as an indicator by which homeowners can recognize argon gas-filled windows.

Argon is denser than air; hence the argon gas-filled window is more energy-efficient than the air-filled double or triple-pane window. Moreover, the thermal conductivity of argon gas is 67% lower than that of air, hence minimizing heat transfer dramatically.

The initial cost of an argon gas-filled window is higher than an air-filled window, but the long-term energy reduction of the former will easily outweigh the latter.

The argon gas does not corrode window materials as oxygen does. As a result, the maintenance and repair costs are reduced. It is important that the argon gas-filled windows are sealed perfectly to prevent the loss of argon gas and avoid a subsequent reduction in the performance of the window.

Why do Builders Choose Argon Gas-Filled Windows?

The selection of argon gas-filled windows by builders is due to its insulation capabilities, which reduce the overall energy consumption of the house.

Argon gas does not pose any danger to the health of the occupants when it is released into the living space. It dissipates quickly in a well-ventilated space. If the quality of the window is good, the argon gas will remain in its space for a long time.

If an amount of argon escapes because of any reason, the remainder can still hold the insulation easily. Argon can be combined with low-E glass to produce well-insulated windows. The gas improves the sound insulation of the window considerably, so it is an excellent choice for houses located in loud areas.

Argon gas-filled windows are desirable for business owners since the gas is inexpensive, and these windows increase the value of a building. New building codes are increasingly imposing energy-stringent standards, so using argon gas-filled windows is an appropriate way to meet Building Code requirements.

FAQs
