If you’re shopping for energy-efficient windows, you’ve probably heard about argon and krypton gas. These gases are used between the glass panes to make your windows better at keeping heat inside during winter and outside during summer.
Both options help lower energy bills, reduce drafts, and make your home more comfortable, but which one is better? And is it worth paying extra for krypton?
Let’s break it all down in simple terms so you can make the best choice for your home.
What Are Argon and Krypton Gas Windows?
Regular windows have air between the glass panes, but air doesn’t insulate well—it lets heat pass through easily.
Argon and krypton gas are used instead of air because they’re denser and slow down heat transfer. This means your home stays warmer in winter and cooler in summer, reducing the strain on your heating and cooling system.
- Argon gas is a common, affordable option that improves insulation.
- Krypton gas is even denser, providing better insulation but at a higher price.
Both gases are completely safe, non-toxic, and invisible—you won’t see or smell them inside your windows.
Which One Insulates Better?
Both gases improve energy efficiency, but krypton is more effective because it’s denser.
- Argon gas: Reduces heat loss better than air, making it a great budget-friendly upgrade.
- Krypton gas: Slows down heat transfer even more, which means even better insulation.
If you live in a mild climate, argon gas is usually good enough to improve insulation. But if you live somewhere very cold or hot, krypton gas can make a big difference in keeping temperatures stable inside your home.
Which One Works Best for Different Window Types?
The gas type you choose depends on the size of the gap between the glass panes.
- Argon gas works best in double-pane windows because it needs a wider space (about ½ inch) to be effective.
- Krypton gas is better for triple-pane windows because it works in narrower spaces (¼ inch or less).
If you’re installing triple-pane windows, krypton is the better choice. But if you’re sticking with double-pane windows, argon is more practical and cost-effective.
Which One Saves More Money on Energy Bills?
Both gases help reduce heating and cooling costs, but krypton offers slightly better savings.
- Argon gas: Lowers energy bills by about 20% to 30% compared to regular windows.
- Krypton gas: Can reduce energy costs by 30% to 40%, especially in extreme climates.
While krypton saves a bit more money over time, the difference might not be huge enough to justify the extra cost unless you live in an area with harsh winters or hot summers.
Which One is More Affordable?
Argon gas is the cheaper option, while krypton is more expensive due to its superior insulation.
- Argon gas windows: Cost about $40 to $50 more per window than standard double-pane windows.
- Krypton gas windows: Cost $100 to $150 more per window, making them more of an investment.
If you’re upgrading multiple windows, the price difference adds up fast. If you’re on a budget, argon is the best value. But if you want the most energy savings possible, krypton might be worth it.
Which One Works Better for Noise Reduction?
If you live on a busy street or near loud neighbors, gas-filled windows help reduce noise.
- Argon gas: Offers good soundproofing, blocking moderate noise like traffic or barking dogs.
- Krypton gas: Because it’s denser, it blocks even more noise, making it a great option for high-traffic areas or cities.
If you want a quieter home, krypton gas-filled windows will block more outside noise than argon.
Which One Lasts Longer?
Both gases will eventually leak out over time, but this happens very slowly—usually at a rate of less than 1% per year.
- Argon gas windows last about 20 years before the gas escapes enough to reduce insulation.
- Krypton gas windows can last over 25 years, thanks to its higher density.
Both options will keep your home energy-efficient for decades, especially if you choose high-quality windows with good seals.
What Happens If the Gas Leaks Out?
If your window seal fails, the gas inside will slowly escape, reducing insulation. But don’t worry—this won’t harm your health or damage your home.
Signs your window might be leaking gas:
- Condensation between the panes (foggy or cloudy glass).
- A noticeable draft near the window.
- Your energy bills start rising without another explanation.
To prevent leaks, make sure your windows have strong, high-quality seals and consider getting professional installation.
Which One is Better for the Environment?
Both gases are eco-friendly because they reduce the amount of energy needed to heat and cool your home.
- Argon gas is more common and requires less energy to produce.
- Krypton gas is rarer and takes more resources to extract, making it less environmentally friendly.
If you’re looking for a greener choice, argon gas is the more sustainable option.
FAQ: Argon vs. Krypton Gas Windows
1. Is krypton gas worth the extra cost?
Krypton is better for insulation, but it’s more expensive. It’s worth the price if you live in an extreme climate or want the best energy savings.
2. Can I mix argon and krypton gas in windows?
Yes! Some high-end windows use a mix of both gases to balance cost and performance.
3. How long do argon and krypton gas windows last?
Both gases last 20-25 years before they start leaking out. Proper sealing and installation help them last longer.
4. Can I refill my windows with gas if it leaks out?
No, once the gas escapes, you can’t refill it. The best solution is to replace the window or the glass unit.
5. Do all energy-efficient windows use gas?
No, but most modern double-pane and triple-pane windows are filled with argon or krypton gas to improve insulation.
