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

- Honestly, I’m not convinced the fancy gases are worth the extra bucks unless you live somewhere that gets crazy cold or hot. My house is from the 80s, and when we swapped out the old windows a couple years back, I went with basic argon double panes. Installer said unless you’re in Alaska or Arizona, you probably won’t notice much difference in your energy bill with krypton.

- Frames - yeah, that’s a whole thing. Vinyl can warp if your house shifts (which mine totally did after a wet spring), and then poof… there goes your seal. Fiberglass is supposed to be more stable, but it’s pricier and still depends on how well everything’s put together. I’ve seen both types fog up in my neighborhood, so honestly, I think the installer matters more than the material.

- Sealant quality is huge, but even then, nothing lasts forever. I had a neighbor who paid top dollar for triple pane krypton windows - looked great for three years, then started getting that cloudy look. He was not happy.

- For me, the “fancy gas” feels like buying premium gas for a Honda Civic…it’ll run fine either way unless you’re really pushing it.

- If you’re planning to stay in your house forever and want bragging rights at block parties (“Check out my krypton gas retention!”), maybe it’s worth it. Otherwise? I’d just focus on good installation and decent materials.

I guess if you like gadgets and features for their own sake, go wild - but for most of us, basic does the job just fine.

Yeah, I’m with you on this. I went basic argon when we redid our windows too, and honestly, I haven’t noticed any crazy difference in comfort or bills compared to my neighbor’s “premium” setup. The installer actually warned me that unless you’re dealing with extreme temps, the extra spend on fancy gases just doesn’t pay off.

What’s made the biggest difference for me is who did the work - my friend went with a cheaper crew and ended up with drafts and foggy panes in less than two years. Materials matter, but install quality seems to matter more. If I ever upgrade again, I’m putting most of my budget toward getting someone reputable to do the job right.

- I get where you’re coming from, but I actually went with krypton for the north-facing windows in my place - mostly because we get brutal winters here.
- Cost was higher, but honestly, I noticed a bigger difference than I expected. Upstairs rooms felt less drafty and the furnace didn’t have to work as hard.
- Agree that install is huge. But in some climates, the “fancy” gas can be worth it… just maybe not for every window.
- If your weather’s milder, argon probably does the job fine. For me, a mix made sense.

I get the appeal of krypton, especially with tough winters, but honestly, I went a different route. My place is older - insulation isn’t perfect - so I focused more on tightening up the frames and adding storm windows.

“But in some climates, the ‘fancy’ gas can be worth it… just maybe not for every window.”

Totally get where you’re coming from. I’ve got an old house too and honestly,

“most of the drafts came from the install or the frame itself, not the glass.”

Funny enough, I’ve actually had folks ask about swapping to krypton or whatever fancy gas, thinking it’ll solve all their draft problems. But like you said, in most of the older homes I work on, the real culprit is almost always the frame or the way the window was installed. I’ve seen 100-year-old sashes with single-pane glass that felt cozier than some brand new double panes - just because someone took the time to insulate and seal everything up tight.

I did a job last winter where we used basic argon-filled units, but spent a chunk of time adjusting the fit, adding weatherstripping, and sealing gaps. The homeowner was honestly shocked at how much warmer the place felt. Upgrading to a pricier gas wouldn’t have made half the difference. Unless you’re in some extreme climate or building a super high-efficiency house, I’d say focus on the basics first. Fancy gases are cool on paper, but they don’t fix a crooked frame or an air gap around the sash…

- Nailed it with this:

Fancy gases are cool on paper, but they don’t fix a crooked frame or an air gap around the sash…

- Seen way too many folks get sold on "premium" gas fills, then call back because their brand new windows still leak cold air.
- Honestly, I'd rather have a well-installed basic unit than a high-end one slapped into a wavy opening.
- Weatherstripping and caulk do more for comfort than most people realize.
- Krypton’s neat if you’re chasing that last 1% of performance, but for most homes? Not worth the upcharge.
- Glad to hear others focusing on fundamentals first. That’s what actually keeps folks warm.

I get where you’re coming from about fundamentals - no question, a poor install ruins any fancy glass. But I’ve actually seen cases where a good low-e argon setup made a noticeable difference, even in an older house after we tightened things up. Sometimes it’s not just about the last 1% - in colder zones, that “premium” fill can bump comfort more than folks expect. I guess it depends how drafty the rest of the place is, but I wouldn’t write off gas upgrades entirely. Anyone else notice that, or am I just seeing outliers?

I’ve wondered about this myself, especially after we swapped out our old aluminum windows for double-pane with argon a couple winters ago. I was pretty skeptical - my wife joked that the only thing that would change was the balance in our checking account. But honestly, there was a real difference. The living room used to have this weird cold “drift” every night, and it mostly disappeared after the upgrade. Could be partly psychological, but I don’t think so.

That said, I also get what folks say about the basics mattering more. If your weatherstripping is shot or you’ve got gaps around the frames, no fancy gas is gonna save you from drafts. We learned that the hard way in our upstairs bedroom; even with good glass, you could feel air sneaking in until we finally sealed up some cracks.

I do wonder if some of the “premium” gases like krypton are worth it unless you live somewhere Arctic-level cold or have money to burn. Argon seemed like a reasonable middle ground for us - noticeable bump in comfort without feeling like we were paying for magic beans. I guess if I had an unlimited budget (and maybe a house that wasn’t built in the ‘60s), I’d consider going fancier just out of curiosity.

Anyone else notice their utility bills shift after upgrading? Ours dipped a bit, but not enough to make me want to replace every window in the house all at once. Maybe it’s one of those “nice to have” upgrades if you’re already planning bigger renos... or if you just really hate wearing socks indoors all winter.

We swapped to argon-filled double panes a few years back, and I noticed the same thing - less of that cold drafty feeling, especially in the rooms that used to be the worst. Our heating bill dropped maybe 8-10% over the winter, which isn’t earth-shattering but was enough to notice. I’ve looked into krypton and even xenon, but honestly, unless you’re in a super cold climate or building new, it feels like diminishing returns for the price. Like you said, fixing air leaks and insulation gave us more bang for our buck than any “premium” gas ever could.

Honestly, I get the hype around “premium” gases, but unless you’re living in the Arctic or building a passive house from scratch, argon seems like the sweet spot. I did a ton of research before swapping mine out - krypton just didn’t seem worth the price jump for a few percent more efficiency. Plus, sealing up those weird gaps around my old windows made a bigger difference than any fancy gas could. Sometimes I wonder if the window companies just want to sell us on the next shiny thing...

“krypton just didn’t seem worth the price jump for a few percent more efficiency. Plus, sealing up those weird gaps around my old windows made a bigger difference than any fancy gas could.”

Couldn’t agree more. I swapped out my panes last summer and went with argon too - couldn’t justify paying double for krypton when, honestly, drafty frames were the real problem. Plugged those up with some cheap weatherstripping and felt the difference right away. Sometimes it feels like window companies are selling snake oil with all these “premium” upgrades... unless you’re living in a science lab or something, argon’s plenty good.

- Argon’s usually the sweet spot for most homes. Cost-effective, solid performance.
- Krypton only makes sense in ultra-thin triple panes or extreme climates - otherwise, you’re paying a premium for minimal gains.
- Air leaks and poor seals are the real energy killers. Upgrading the gas won’t fix those.
- Seen plenty of people surprised by how much weatherstripping alone helps. Fancy gases can’t compete with stopping drafts.
- Honestly, unless your windows are already top-notch, upgrading to krypton is like putting race fuel in an old sedan... just not worth it for most folks.

I hear what you’re saying about argon being the go-to, and I mostly agree - it’s what I have in my own windows, and it’s worked fine for years. But I do think there are situations where krypton can actually make sense, even outside of super cold climates or ultra-thin panes.

Krypton only makes sense in ultra-thin triple panes or extreme climates - otherwise, you’re paying a premium for minimal gains.

In my case, I live in a 1960s split-level that we’ve been slowly updating. We installed triple-pane windows on the north side because that part of the house gets hammered by wind all winter (northern Minnesota - brutal). The installer offered krypton as an option for those windows. It wasn’t cheap, but after two winters, I have noticed less frosting and a more consistent temp in those rooms compared to the rest of the house with double-pane argon. I’m not saying it’s night-and-day, but the difference is real enough that I’d consider it again if I ever redo the south-facing side.

I do agree with you on air leaks and seals being a bigger deal than gas fills, though. Before we did any window upgrades, we spent a weekend with caulk and weatherstripping around every door and window frame. That made a huge difference right away - probably more than any fancy gas could.

But sometimes the “race fuel” analogy doesn’t quite fit if you’re already investing in good windows and live somewhere with rough winters. In milder climates or older homes with drafty frames, yeah, krypton’s probably overkill. But up here? It’s not just marketing hype.

Curious if anyone else in colder states has tried both gases - maybe my experience is just because our weather is so extreme.

That’s interesting to hear about your experience with krypton, especially in northern Minnesota. I get what you’re saying about it not being a night-and-day difference, but still noticeable. Sometimes those small changes really add up in comfort, especially when you’re dealing with brutal winters and wind like that.

This caught my eye:

I’m in upstate NY, so not quite as cold as Minnesota, but we get our share of nasty wind off the lake. I’ve only ever had argon in my windows, and honestly, it’s been fine for me. But I can see how, in your situation, the extra spend for krypton might be worth it. Especially with those north-facing rooms… there’s always that one side of the house that just gets hammered.

For me, price is a factor. If I was doing a full gut reno or building new, maybe I’d consider krypton for certain spots. But for most people, argon + good sealing does the trick. Still, it’s good to hear real-world feedback from someone actually living with krypton - sometimes you wonder if the numbers on paper actually translate to comfort.

Nice work sticking with the upgrades over time. Those older split-levels can be a pain to modernize, but sounds like you’re making smart calls.

Honestly, I’m with you on the basics making the biggest difference. I sealed up my 80s ranch before even thinking about window gases, and it was like night and day for drafts. Argon’s been fine for me, too - couldn’t justify the extra cost for krypton, especially since my windows aren’t all that new anyway. Sometimes it feels like the “premium” options are more about marketing than real-world impact, unless you’re in super extreme climates or doing a full rebuild.

Couldn’t agree more about the basics - air sealing and insulation always give you the biggest bang for your buck. I’ve swapped out a lot of windows, and honestly, unless you’re living in the Arctic, argon does the trick. Krypton’s like putting racing fuel in a minivan... neat, but kinda pointless for most folks.

That analogy nails it. Most of my clients are surprised how much difference just sealing up gaps and adding insulation makes before even touching the windows. Argon’s been solid in my own house - never felt the need to go fancier, especially when the price jumps pretty fast. If you’re not dealing with crazy temps, sticking with argon and focusing on tight seals is usually the sweet spot.

- Agree, argon’s the practical choice for most climates.
- In my experience, getting the window frame sealed right does more than swapping gases.
- Krypton’s cool tech, but unless you’ve got super thin triple panes or live somewhere like Fairbanks, it’s hard to justify the cost.
- Did one install with krypton as a test - honestly, couldn’t feel much difference day-to-day compared to argon.
- For most folks, spend your money on better installation and weatherstripping first... that’s where the comfort really comes from.

1. Figure out your budget first. Fancy gases like krypton sound cool but the price difference is real, especially if you’ve got a lot of windows.

2. Check your climate. I’m in a pretty average spot, not crazy cold or hot, and argon seems to do the job just fine. Haven’t noticed drafts or big temp swings since we got new windows.

3. Focus on the seals and frames. We had an installer who didn’t seal one window right - felt the cold air every time I walked by, no matter what gas was in there.

4. If you’re thinking about triple panes or specialty glass, maybe then look at krypton? But for most of us, I don’t see the point unless you’re chasing absolute max efficiency.

Has anyone actually seen their energy bills drop a lot after switching gas types, or is it mostly about how well everything’s installed?
