Benefits of Argon Replacement Windows

replacement windows in Carlsbad, CA

Insulated glazing units (IGUs) are either double-paned or triple-paned. And sealed between each pane of glass is a special gas fill. Argon gas is commonly used for replacement windows in Del Mar, CA to increase energy efficiency and thermal performance. Argon helps slow heat transfer through the window. This keeps the inside of the home cool on hot days, and warm on cold days. Read more to find out if argon replacement windows are the best for your home.

The Problem with Old Windows

Old windows were generally double-paned, air-filled glazing units. But unfortunately, air often contains moisture and is much more reactive. It expands and contracts with temperature changes, which would cause the seals on these windows to break down much faster. This would eventually lead to higher energy losses through the glass.

Why do Window Manufacturers Use Argon?

Argon is a noble gas, which signifies it as a member of a certain group of gases on the period table. They are known as inert or noble gases because it was long believed that these elements were completely unreactive. More study has proven this false, but still, they are highly stable with extremely low reaction rates. What does this mean for replacement windows? Argon is colorless, odorless, and completely non-toxic. But it has more density than normal air and does not react to temperature fluctuations. This means heat doesn’t readily transfer through it.

Benefits of Argon Replacement Windows

Here are some of the advantages of argon gas fills on replacement windows:

Cost Savings

Upfront, the cost of argon is lower than some of the other gas fills. This is because argon makes up a higher percentage of the atmosphere. It is more abundant in the atmosphere than xenon and krypton—the two other noble gasses used as gas fills. And because it is more readily available, that makes it easier to access and more affordable.

Energy Savings

With argon windows, you not only get upfront savings but also long-term savings. Argon-filled windows will help reduce the amount of solar radiation passing through the glass. This will keep indoor temperatures cooler without as much reliance on the HVAC system. The same can be said for radiant heat escaping the home in the winter. In short, argon replacement windows will save money on your monthly heating and cooling costs. And year after year those savings can add up.

Frost Reduction

Because argon windows are more efficient, they help insulate the interior surface of the glass. This reduces the risk of condensation and frost on those really cold days.

Noise Reduction

Argon gas fills, because they have more density, can also help with the reduction of sound pollution. You will notice a marked difference in noise reduction if you are going from single-paned windows to double-paned windows. And if you are looking for even more advanced soundproofing then you can check out special laminated coatings specifically designed to reduce vibrations.


As stated before, argon gas is a natural part of the atmosphere. It is non-toxic and completely safe. Even if the glazing unit breaks and the gas leaks out, there is no danger from it.
