Argon gas makes up less than 1 per cent of the earth’s atmosphere.
That might seem like a little, but it’s actually quite a lot. And there’s plenty to spare for your windows! This non-toxic odourless gas transforms your regular glazed windows into something a little more efficient.
Argon Gas filled windows feature a double or triple glazed unit that is filled with gas between the panes of glass to increase energy efficiency and soundproofing.
Argon Gas increases the windows ability to insulate by reducing the heat transfer. Argon Gas does not conduct heat as readily as air, so it helps keep heat in during the winter and out in the summer at the same time as an advantage in decibel reduction.
Argon Gas Windows & Heat Conduction Properties
Argon is a less conductive gas than the ones present in regular air. The panes between the windows are filled with argon gas. This layer of gas acts as a thermal blanket, reducing the heat transfer between the inner and outer window pane.
This makes heat loss from the inside of your home is lower during the winter, and heat gain from the outside is also lower during the summer. It’s an all-climate solution, that works great during every season of the year.
WHAT DOES ARGON GAS LOOK LIKE? WILL I SEE IT IN MY WINDOWS?
No, Argon Gas is clear, colourless and odourless. Even if installed side by side, you cannot see the difference between a window filled with gas and one without.
HOW LONG WILL THE GAS STAY IN THE WINDOW?
Numerous studies show that gas typically leaks out at less than 1% per year. Over twenty years the window still has at least 80% of the gas still trapped inside it.
IS ARGON GAS DANGEROUS?
An emphatic NO! Argon Gas exists naturally in the air you breathe – it is both non-toxic and inert.
WILL MY HOUSE PLANTS GROW?
Argon does not block any portion of the suns light. House plants will not be affected.
WILL ARGON GAS GIVE ME AN A-ENERGY RATED WINDOW?
No. Filling the glass sealed unit with Argon Gas alone will not give you an A-energy rated window. Whilst it will improve the thermal efficiency of the window, other measures need to be taken.
Sealed units used to have aluminium spacer bars separating the two panes of glass – these were conductors of heat and cold. Now spacer bars are made of an insulating plastic composite material that becomes a barrier to heat loss. We use the Warm Edge Spacer which does exactly as it ‘says on the tin’ – keeping the edge of the sealed unit warm. At the same time, the window frame needs to be manufactured in a way that meets a standard of thermal efficiency as well as be certified with a Window Energy Rating (WER) to confirm the whole window in its entirety has been correctly produced.
IS IT ONLY FOR ENERGY SAVINGS?
Whilst energy savings are important, the real “comfort” benefit of gas filling the sealed unit is the increase in the inner glazing temperature. Raising the inner glass temperature acclimatises or substantially reduces condensation on the glass. A “warmer” surface is also more comfortable to be near.
There is also a soundproofing element.
DO ALL WINDOWS HAVE ARGON GAS?
Unfortunately not! Gas-filled windows are manufactured using specialised equipment and not all manufacturers have these facilities. So when buying new windows make sure your supplier can offer the benefits of Argon Gas for that extra insulation.
Additional Benefits Of Argon In Windows
Normal air contains moisture that causes cloudiness and condensation on window panes. As one of the more affordable non-toxic gases, it comes with a variety of additional benefits.
- It improves the thermal performance of your windows
- Lower possibility of condensation, frost and the build-up of moisture
- Pairs well with low-E coatings
- It is inexpensive, odourless and non-toxic
- Assists with room insulation
- Works well under all climatic conditions
- Fits in well with most window designs
- It is a non-corrosive substance that is safe for both, your windows and the environment
- Can help to soundproof your home
Argon vs Krypton Gas For Your Windows
While argon gas is the more popular choice for windows, krypton is another alternative that is sometimes used. How do you determine which one is right for you?
Krypton gas is a relatively denser gas. It also tends to be more expensive, and harder to obtain. Generally, argon is the preferred option because it is more easily available, gives reliable results, and is also extremely affordable in comparison.
While krypton gas is also odourless and non-toxic, you get better value for your money with argon. If you’ve got double-paned windows, with a wider space, argon gas is definitely your best option.
How Long Does Argon Gas Last In Your Windows?
Argon gas windows that are installed correctly, can last you more than twenty years. Of course, over time it is natural for very small amounts of gas to leak, but this will not affect the efficiency of the windows during that time.
If you notice condensation or moisture on your window panes, it’s probably a good indicator of a gas leak or similar problem. If you feel like your windows are no longer functioning like they used to, you should get in touch with a window repair service to investigate the issue.
