Krypton Vs Argon
Windows don’t just provide light and air into your home, they’re also an integral part of your heating and cooling system. Keeping the cold out in the winter and stopping your home getting too warm in the summer, it’s essential that your windows have good levels of insulation.
But have you ever stopped to wonder exactly what’s in a double-glazed window pane? It may look just like air between the two layers of glass but it’s actually a gas. Many double-glazed windows use Krypton or Argon gas to achieve the very best insulation possible.
In the technical specification of the windows you’re buying, you should be able to find out which gas is used. Here’s what you need to know about Krypton and Argon gas, including the benefits and drawbacks of each.
Why choose a gas-filled window?
Double-glazing has come a long way since it was first created, and now has a range of options to improve insulation. Having simple layer of glass between your home and the outside isn’t sufficient to provide the maximum possible insulation.
Pumping gases such as Krypton and Argon in the space between the panes provides far superior insulation. Heavier than air, the gases help to maintain a constant temperature in the home as well as offering better soundproofing too.
Gas can also help to prevent the annoying condensation from appearing on your double-paned windows, providing protection against corrosion.
Krypton and Argon are both noble gases, previously known as inert gases. This means that if the seal on your window somehow breaks, there’s no risk of a dangerous chemical reaction or explosion. Noble gas is completely harmless and won’t hurt you or damage your property in any way.
There’s no question that having gas in your double-glazing provides excellent benefits but which one should you choose?
Argon is a gas that’s particularly abundant which means it’s economical to use and easy to acquire. As it’s heavier than air it can prevent the corroding actions of oxygen as well as keeping drafts out more effectively.
Although it works in a similar way to Krypton it’s a far cheaper gas which makes the balance of investment and savings far more favourable to the customer. For this reason, Argon is typically used for standard gaps of 12-16mm between the panes.
Thermal performance could improve by almost a third compared to air-filled double-glazing but much depends on the thickness of the panes of glass.
No, this has nothing to do with Superman! Krypton is another noble gas that performs in a very similar way to Argon. Slightly higher in quality and more dense, it’s an extremely effective form of insulation for double or triple pane windows.
Krypton is typically used for thinner windows, where the gap between the panes is much smaller, such as heritage windows. This preserves the authentic aesthetic without compromising on thermal performance.
The only real drawback of Krypton is that it’s a much rarer gas, existing in quantities in the atmosphere of one part per million. This makes it a more expensive option and why it’s primarily used in smaller quantities.
