IF YOU COULD UPGRADE YOUR WINDOWS TO A DIFFERENT GAS, WOULD YOU GO FANCY OR STICK WITH BASIC?

Totally get the logic behind focusing on air sealing and insulation first. I’ve had a similar experience - did a bunch of caulking and put in new attic insulation before even touching the windows, and right away noticed the house just felt less drafty. Like you said,

“Heating bill dropped more from the insulation than the windows.”

“Heating bill dropped more from the insulation than the windows.”

You nailed it - air sealing and insulation usually give you the fastest bang for your buck. I’ve seen so many folks jump straight to fancy triple-pane krypton-filled windows, only to realize their attic is basically a sieve. That said, if your house already has solid insulation and you’re still feeling drafts or seeing condensation, then higher-end windows (with argon or even krypton) can make sense, especially in harsher climates. But honestly, unless your windows are ancient or single-pane, the ROI on “fancy gas” is often more modest than the marketing suggests. Sometimes I think window companies just like saying “krypton” because it sounds like Superman’s involved...

I’m with you - insulation and air sealing made a bigger dent in my bills than any window swap ever did. When I got quotes for krypton windows, the price jump over argon was wild, and honestly, I couldn’t justify it for my 1960s ranch. Here’s what worked best for me: 1) Seal up the attic and rim joists, 2) beef up insulation, 3) only THEN look at windows if drafts or condensation stick around. If your windows aren’t falling apart, argon’s usually plenty. Marketing’s great at making you think you need more... but sometimes “basic” is just fine.

Krypton always sounds impressive on paper, but the cost-to-benefit ratio just isn’t there for most homes - especially older ones. Argon’s thermal performance is solid for the price, and unless you’ve got super high-end windows or live somewhere with brutal winters, it’s hard to justify the upgrade. I’ve seen better returns from tightening up the building envelope and adding insulation, like you said. Windows are flashy, but the basics usually win out.

You nailed it - argon usually gives you the best bang for your buck. I've swapped out a lot of old windows, and unless the house is super tight and already has top-tier insulation, krypton just doesn't move the needle enough to justify the cost. Honestly, most drafts I see are from poor seals or gaps, not the gas itself. If you really want to boost efficiency, start with air sealing and attic insulation... then look at window upgrades if you still need more.

I’ve looked into krypton, but honestly, like you said, unless your house is already sealed up tight, it’s overkill. Most of my energy savings came from fixing leaky door frames and adding more attic insulation. Windows were way down the list for me.

You’re spot on - addressing leaks and insulation usually gives the highest return. I’ve seen a lot of people jump to “fancy” window upgrades, but unless, as you said,

“your house is already sealed up tight, it’s overkill.”

Yeah, I kinda wondered about this too. Like, all the ads make it sound like getting the “fancy” gas-filled windows is the magic fix, but honestly, my old place was drafty as heck and I could literally feel the wind coming in around the frames. Didn’t matter what was inside the glass at that point. I ended up just doing a bunch of caulking and adding insulation in the attic, and my bills dropped way more than when I swapped out a couple windows.

I mean, I get the appeal of new windows - they look slick and all - but if your house is still leaking air everywhere else, it’s like putting a band-aid on a leaky boat. Not saying the upgrades aren’t cool if you’ve already done everything else, but for most folks, seems like the basics go further. Props for not falling for the hype right away.

Yeah, totally agree with the “band-aid on a leaky boat” vibe. I’ve seen folks drop big bucks on triple-pane, argon-filled windows and still wonder why their house feels drafty. Truth is, if you’ve got gaps around the frames or your attic’s basically an icebox, that fancy gas isn’t doing much. I always tell people - air sealing and insulation first, then worry about the bells and whistles. Windows are cool, but they’re not magic on their own.

Funny thing, I’ve actually had customers who wanted krypton gas windows because they read somewhere it’s “the next level” for insulation. But honestly, unless you’re building a super-tight new house or you live somewhere with wild temperature swings, I’ve never seen the payoff. Like, yeah, on paper krypton’s better than argon, but the difference is so marginal in most homes that you’d be hard pressed to notice it - especially if the rest of the house is leaking like a sieve.

One time I swapped out all the windows in a 1950s ranch for high-end stuff, but the real game changer was when we sealed up the rim joists and blew more insulation into the attic. That’s what actually made the place feel cozy.

Curious if anyone here has tried those fancy gasses and actually noticed a difference? Or does it mostly come down to how tight your house is overall?

I’ve wondered about this too. I mean, the numbers look great on paper, but in my last place (built in the 60s), I went with argon and focused more on fixing drafts and adding attic insulation. That made a way bigger difference than the windows themselves. I guess if you’re already at “airtight fortress” level, maybe the fancy gas is worth it, but for most houses, it seems like overkill. Your story about sealing up the rim joists totally lines up with my experience - sometimes it’s the boring fixes that make things actually comfortable.

I hear you on the “boring” fixes making the biggest impact. Years ago, I blew a bunch of money on triple-pane windows with krypton gas for our old ranch, thinking it’d be a game changer. In reality, it was plugging up the leaky crawlspace vents and adding some basic weatherstripping that finally stopped those cold drafts. Makes me wonder - has anyone actually felt a difference between argon and the pricier gases, or is it mostly just numbers on a spec sheet?

- Tried the “fancy gas” route once (krypton, felt very James Bond at the time). Honestly, couldn’t tell a difference from the cheaper argon windows in our old place.
- Like you, sealing up the weird little gaps and slapping on some weatherstripping made a way bigger impact than the gas inside the glass.
- If you’re in a super cold climate, maybe it matters more... but for most of us, I think it’s just marketing hype and numbers that look good on paper.
- My wallet still remembers the krypton upgrade, though.

- Kind of surprised to hear krypton didn’t make a difference for you. I always thought the fancier gases would be a game changer.
- My neighbor swears by his triple-pane krypton windows, but he’s up in northern Minnesota where it gets brutal. He claims his heating bill dropped a lot.
- Maybe it’s just not worth it unless you’re somewhere with extreme temps? I’m in a pretty mild area, so maybe argon’s fine here.
- Weatherstripping definitely seems like the best bang for your buck, though. Did that last winter and noticed way less draft.

Maybe it’s just not worth it unless you’re somewhere with extreme temps? I’m in a pretty mild area, so maybe argon’s fine here.

I kind of wrestled with this exact question when I replaced my windows a couple years ago. I live in the Pacific Northwest, so we get some chilly days but nothing like Minnesota. The window guy tried to upsell me on krypton, but honestly, the price jump was wild. I ended up sticking with double-pane argon, and I don’t feel like I’m missing out. The house feels way less drafty, but I think that’s mostly because I finally sealed up the gaps and replaced the ancient weatherstripping.

Triple-pane with krypton sounds cool on paper, but I’m not convinced it’s worth the extra cash unless you’re fighting off subzero temps for months. I’d rather put that money into attic insulation or even a better thermostat. Sometimes the “fancy” stuff just doesn’t move the needle unless your climate really demands it.

I do wonder if the marketing around these gases makes us think they’re more important than they are... Anyone else feel like that?

I get what you mean about the marketing hype. When I looked at window options for our place, the salesperson made krypton sound like some sci-fi upgrade, but the cost just didn’t make sense for our climate. I’m in a mild zone too, and honestly, after swapping to argon and fixing some leaks, the difference was night and day - mostly because of air sealing, not the gas itself. Makes me wonder if the real value is just basic upgrades and maintenance rather than chasing the fanciest tech every time. Anyone else notice that with other “upgrades” around the house?

I’ve definitely run into the same thing with other “upgrades” around the house. We did a kitchen reno a couple years ago, and the contractor kept pushing these ultra-premium drawer slides - supposedly smoother, quieter, all that. But honestly, after installing some solid mid-range hardware and just making sure everything was level and adjusted right, I haven’t noticed any difference in day-to-day use. It’s like with windows: the basics done well seem to matter more than the fanciest features.

With windows specifically, I went with argon for our 90s-era place. The installer said unless you’re in extreme climates or have super thick glass units, krypton doesn’t really add much for the price. What really made a difference was tracking down drafts around the frames and sealing those up. It’s not flashy, but it’s where the comfort (and savings) actually show up.

Sometimes I wonder if half these “advanced” options are more about marketing than real-world results, especially in average homes. Maybe there’s a place for them in high-end builds or tough climates, but for most of us... basic maintenance and smart choices go further.

I get where you’re coming from, but I think there’s a bit more nuance with the gas fills in windows. Argon is definitely the go-to for most standard double panes, but I’ve seen measurable differences with krypton in certain setups - especially triple-pane units where the space between glass is narrower. It’s true that

“unless you’re in extreme climates or have super thick glass units, krypton doesn’t really add much for the price.”

I get the appeal of krypton, but honestly, most folks I work with don’t see enough of a difference to justify the extra cost unless they’re in deep freeze territory. Argon’s been solid for my clients - even in some pretty drafty old houses. Sometimes the basics just do the trick, especially if your budget’s tight.

I keep hearing that argon is the go-to for most situations, but I’m curious - does anyone notice a difference in noise reduction between argon and krypton-filled windows? I get that

“most folks I work with don’t see enough of a difference to justify the extra cost unless they’re in deep freeze territory.”
