That’s a good point, but I’ve always wondered—how much difference does the gas actually make if you’ve already got double or triple panes? I mean, is the jump from argon to krypton really noticeable in day-to-day comfort, or is it more of a “numbers on paper” thing? I’ve sealed up most of my leaks over the years, but I still get cold spots near the windows on windy days. Is that just the glass, or could it be something else? Sometimes I feel like there’s only so much you can do before you hit diminishing returns...
- Totally hear you on the diminishing returns. Once you’ve got double/triple panes and sealed leaks, the gas in the window is just one piece of the puzzle.

“Is the jump from argon to krypton really noticeable in day-to-day comfort, or is it more of a ‘numbers on paper’ thing?”
- For most homes, it’s mostly “numbers on paper.” Krypton does insulate better than argon, but unless you’re in a super cold climate or doing a deep energy retrofit, you probably won’t feel a dramatic difference.
- The U-value drop between argon and krypton is there, but it’s pretty incremental—like, tenths of a point. Not nothing, but not game-changing either.
- Cold spots by the windows could be:
- Air leaks (even tiny ones you can’t see)
- Poor insulation around the window frame (the wall itself)
- Convection currents—cold glass cools air, which drops to the floor and feels drafty even if there’s no leak
- I’ve got triple panes with argon in my place (built in the 80s) and still get that “chill” near the glass on windy days. Turns out, a lot of it was the wall insulation right under the window—once I beefed that up, it helped more than anything fancy inside the glass.
- Cost-wise, krypton is way pricier than argon. Unless you’re going for passive house standards or live somewhere like northern Minnesota, I’d stick with argon and focus on sealing/insulating around the frames.
- At some point, yeah, you hit that wall where more upgrades don’t pay off much in comfort or bills. Sometimes it’s just physics—glass will always lose more heat than a solid wall.
- If you’re chasing those last few degrees of comfort, heavy curtains or cellular shades can make a surprising difference too. Not as high-tech, but works.
Hope that helps someone else weighing the same stuff.
Honestly, I’ve seen a lot of folks get caught up in the “fancier gas” debate, but like you said,
I’d say the same—argon’s usually enough. I’ve swapped out dozens of windows for clients, and when someone complains about drafts it’s almost always a framing or seal issue, not the gas. Save your money for better insulation or maybe some solid window coverings. The numbers look nice on paper, but real-world comfort rarely matches the hype.“unless you’re in a super cold climate or doing a deep energy retrofit, you probably won’t feel a dramatic difference.”
Honestly, unless you’re trying to build a spaceship, I don’t see the point in going wild with the gas upgrades. I’ve lived through a few Canadian winters and argon’s always been fine. If your windows still feel drafty, it’s usually the install, not the gas.
- Argon’s honestly the workhorse for most homes. It’s cheap and does the job.
- Krypton’s technically better, but you’ll barely notice unless your windows are huge or you’re in extreme cold.
- Drafts almost always mean poor install or bad seals, not the gas itself.
- Seen fancy upgrades that didn’t make a dent because the frame was off... spend your money on a solid install first.
Had a bit of a “grass is greener” moment when I started looking at window upgrades. I read all about krypton and those triple-glazed, space-age options. Got excited, then realized my house is a 1960s ranch with windows that are more draft than glass some days.
I really liked this point:
Drafts almost always mean poor install or bad seals, not the gas itself.
That’s been 100% true for me. I was convinced my old windows were leaking because they weren’t fancy enough, but turns out the seals were just shot. After I replaced the weatherstripping (and did a very questionable DIY caulking job), it made more difference than any gas upgrade would have.
I did talk to one installer who tried to sell me on krypton for “maximum efficiency.” It sounded cool—who doesn’t want their house filled with noble gases? But once he gave me the price, I had to laugh. For my average-sized windows and pretty mild winters, it felt like putting racing tires on a Corolla. Maybe if I lived in Minnesota or had some giant picture windows, but for now, argon’s doing fine.
Honestly, the best money I spent was on making sure the frames were square and the install was solid. My neighbor splurged on high-end glass but skipped proper install, and now she’s got condensation between panes and regrets.
If you’re like me and just want something that works without breaking the bank, basic argon’s hard to beat. The real magic seems to be in the details—tight seals, good frames, and maybe some patience with a caulking gun...
Tried the “fancy” route once, back when we replaced the front windows. The installer made krypton sound like some kind of miracle, but the price tag just didn’t make sense for our climate or budget. Ended up going with basic argon, and honestly, the biggest difference came from fixing the warped frames and resealing everything. My brother-in-law spent a fortune on high-end options, but his install was sloppy—now he’s got drafts and regrets. Sometimes the simple fix really is the best.
Funny you mention the fancy gases—I've seen folks drop serious cash on krypton or even triple glazing, thinking it'll solve everything. But if your frames are crooked or seals are shot, even the fanciest glass won't help much. I once worked a job where a client had top-tier windows but skipped the prep work—ended up with condensation and drafts anyway. In my experience, getting the basics right (good install, tight seals) does more for comfort and bills than any exotic gas. Sometimes simple just works better, especially if you’re not in an extreme climate.
I get where you’re coming from—bad install definitely ruins any upgrade. But I do think there’s a case for the fancier gases in certain situations, even if your climate isn’t super harsh. I upgraded to argon-filled units a couple years back (with proper install, of course), and I noticed less outside noise and slightly better temp control. Not a night-and-day difference, but enough to matter when the street gets loud or the weather swings. Maybe not worth it for everyone, but sometimes those little gains add up over time.
Had a similar debate with myself when we did our reno last year. I’ll be honest, I was tempted to just stick with the basic double-pane because it felt like “good enough” and my wallet was already crying. But my partner talked me into the argon upgrade, and I gotta admit, there’s a difference. Not massive, but enough that I noticed the living room doesn’t roast in the afternoon sun like it used to. Also, street noise—still there, but more muffled now.
That said, I think the biggest improvement came from fixing all those weird little gaps and drafts around the frames. The fancy gas helps, sure, but if your install is sloppy or your old house leaks air like a sieve (mine did), you’re not going to get your money’s worth. If you’re already doing it right, the extra cost isn’t a total waste. But if you’re hoping for miracle insulation… probably not happening.
Honestly, sometimes it feels like we’re all just chasing those tiny 5% improvements...
