Why are windows filled with argon gas/ krypton gas?

These gases include krypton, xenon, nitrogen or oxygen. The newest addition to this roster, however, is argon, which window manufacturers prefer to krypton nowadays. The reason for this is because argon is a cost-effective alternative to krypton without sacrificing energy efficiency.

How to repair argon windows?

Professional defogging contractors follow a simple procedure:

  • The technician drills tiny holes in the glass to expel the moisture from between the glass panes.
  • An anti-fog solution is applied to the inside of the IGU.
  • A liquid sealant is added to the bottom of the glass.
  • A seal is installed in the drilled hole.


Can argon gas windows be fixed?

Argon gas windows can be repaired, and gas can be re-added to the pane if the seals can be replaced. Otherwise, it can be a difficult process that is by no means a long-lasting fix. If your argon gas windows were poorly installed or damaged, gas will continue to seep out whether more is added or not.

Can double-pane windows be refilled?

Yes. If you send out a window professional for an inspection, he or she can gauge the current level of argon gas in your double-pane windows. If a substantial amount has been lost then there is a method to replace the gas between the panes of glass. However, it may only be a short term solution.

Does argon leak out of windows?

While argon gas fills don't expand or contract, the glass it fills does. Once the glass expands, however, the seals that contain the gas between the panes are broken, allowing the argon gas to leak out. In fact, it even leaks from the window even when the seals are intact; the leakage rate is 1% per year.

How do you get rid of moisture between double-pane windows?

How long does argon last in windows?

20 yearsThe National Glass Association states that an argon-filled window won't experience any performance losses so long as it retains at least 80 percent of its gas. That means that, even at the maximum leakage rate, an argon window could last you 20 years before needing to be refilled.

Can argon gas windows explode?

One rare yet shocking consequence of argon leakage is the sudden implosion of the window. Due to molecular differences between argon and the principal components of air, nitrogen and oxygen, argon under pressure to escape a window unit may exit the seal faster than it can be replaced with air.

Hi all. Frequent ex-user of these forums looking for a quick gut-check. My contractor just installed a Ply Gem vinyl picture window, 52x56, double pane, Low-E, Argon filled, and they cracked the exterior pane. The supervisor said someone was coming tomorrow to repair it.

Hey Codnuggets. They are probably going to reglaze the frame. They should bring out another piece of insulated glass (with Lo E, with Argon gas) and take the old cracked piece of insulated glass out. You can't replace just one sheet of the insulated glass. I have a feeling that must be what he was referring to.

If it happens within the window's warranty period, however, your first option should be to contact the window manufacturer to discuss replacement under the conditions of the product warranty.

Why do windows have IGUs?

In these dense gases, the molecules move very much slower under the impact of thermal energy, which means windows with IGUs filled with such gas will create a much better barrier against heat loss. For this reason, nearly all insulated thermal windows now use one of the inert gases to fill the space between panes.

What is an IGU window?

Understanding IGUs (Thermal Windows) Nearly all windows today, whether for new construction or replacement, have, at their heart, an insulated glass unit, or IGU. This means two or sometimes three panes of glass that are factory-sealed together to form a single unit; they cannot be separated. Single pane windows are difficult to find ...

Is an IGU better than a single pane window?

Thus, while an IGU filled with air is much better than a single-pane window at forming a thermal break, there are other options that can do a much better job. The better solution is to fill the space between panes of glass in the IGU with a heavy, inert gas such as argon or krypton.

Can you fix a foggy window?

Foggy windows can be repaired using a defogging procedure. Still a fledgling niche industry, window defogging is capable of producing cosmetic results that help improve visibility in your windows. On the downside, defogging does nothing to restore the window's insulating ability (R-value) to its original level.

Does IGU glass condense?

In the summer, when outdoor temperatures keep the glass warm, the moisture inside the IGU generally does not condense into visible condensation, but as the weather cools, the moist air touching the cold outer glass causes moisture to con dense into visible water droplets.

Argon Gas in Windows: The Pros and Cons

A window’s purpose is not solely ventilation and lighting, so manufacturers offer many choices. Sometimes a choice is made based only on style or color, but there are other features that serve a specific purpose.

What is an argon glass window?

Argon glass windows are those in which the double-pane in a window is filled with argon gas. Argon is a noble, dense, and colorless gas. These properties make it capable of providing thermal insulation for your home.

Benefits of argon glass windows

Be it a residential or a commercial window, energy efficiency is sought after by the owners to reduce their bills. And when we talk about argon windows, one major advantage offered is energy efficiency. This fact accounts for many of those homeowners who choose argon glass for their replacement windows.

Disadvantages of argon-filled glass windows

Due to the expansion or contraction of window materials, esp. the glass, the gas starts leaking. Even if the window materials and weather seals are intact, leakage can happen in argon-filled windows.

Cost of argon-filled windows

The cost of a replacement window is always an important consideration. The initial investment in installing argon-filled windows is rather higher, around $40-$50 per square foot. Nevertheless, these windows contribute to long-term energy savings and reduce your energy costs overall.

Can you get air out of glass?

You won't get all the air out by just trying to displace it with Argon. You would have to pull a vacuum on the space between the panes of glass first like they did at the factory. If you do this you will also find out how hard it is to make a perfect seal using wood.

What happens if a window is not equipped with a glazing bead?

A seal failure, though, will "oxidize" the low-E coating and argon gas, making the glass appear streaky or foggy. Technically, yes, gas could be added to the window. However, from a practical standpoint, it might not be the best solution. The process to add the low-E coating and argon gas is an involved process typically done at the factory.

Can you replace a window with argon glass?

A better option might be replacing the entire window with a newer window that is airtight and already equipped with the low-E/argon glass combination. If you're set against changing out the entire window, adding a new insulated pane of glass might be the most economical and practical way to go.
