What is Argon?

Published on

If you’re in the market for replacement windows, you’ve likely focused on selecting the style and material type that best fits your home. Another key feature to consider is which type of glass will help your home stay most comfortable in every season. Glass can impact the amount of heat or cold that gets inside your house and contribute to energy efficiency.

A key feature of our Low-E insulating glass is that it can include argon. But what is argon? We get that question a lot.

The simple answer is that argon is a colorless, nontoxic gas that’s denser than air. It’s an abundant atmospheric gas, and it doesn’t react with other elements. Argon also has low thermal conductivity, meaning heat does not easily transfer across it. This makes the gas perfect to use as a form of insulation in glass because it slows down the transfer of hot air into your home during the warmer months and slows down the transfer of heat out of your home in the winter.

The Benefits

We use insulating argon between panes of Low-E glass because it provides multiple benefits to our customers. Some results are shared below.

  • Depending on the glass type, Argon blocks 69% to 94% of the sun’s ultraviolet rays, guarding against harmful rays.
  • Argon helps keep your home warmer in the winter and cooler in the summer to help keep you comfortable.
  • Better insulating windows can help lower your energy bills.
