Anyone tried those ultra-slim triple glass windows yet?

That “real air” thing gets me, too. I’ve seen folks get these ultra-slim triples and swear they’ll never crack a window again, but honestly, there’s just something about fresh air—even if it means the neighbor’s dog joins the party. The warmth difference is wild though, especially in older homes where drafts used to be the norm. Curious if you noticed any condensation issues on the inside? Sometimes clients mention that after upgrading, especially if the humidity’s up.

Yeah, the condensation thing caught me off guard the first winter after we swapped out the old single panes for triples. Our house is from the 60s, so it went from drafty to almost too airtight overnight. If we keep the humidity up (like when I forget to turn on the bathroom fan), I’ll get a bit of fog on the corners. Not a dealbreaker, but definitely something to watch if you’re used to just letting the breeze handle it. And yeah, I still crack a window now and then—nothing beats that real air, even if it means hearing the neighbor’s lawnmower at 7am…

That’s exactly what happened to us after our window upgrade—suddenly the house felt like a sealed box. Here’s what worked for us: first, I grabbed a cheap hygrometer to keep tabs on humidity (turns out showers and cooking really spike it). Second, we started running the bathroom fan a bit longer, and sometimes the kitchen vent too. If you forget, yeah, those corners fog up fast. Cracking a window here and there definitely helps, even if it means hearing the neighbor’s dog bark at squirrels all morning. It’s a tradeoff, but the energy savings are worth it.

Totally relate to the “sealed box” feeling after a window upgrade. When we swapped out our old single panes for triple glass (the ultra-slim ones, actually), I was honestly shocked how airtight the place got. It’s wild how much difference it makes—suddenly, every little thing you do inside shows up in the air quality and humidity.

That bit about the hygrometer is spot-on. I thought it was overkill at first, but tracking humidity is basically essential now. I’ve caught a couple spikes after running the dishwasher or even just boiling pasta. And yeah, those corners—especially on north-facing walls—are always where the condensation pops up first if I slack off on ventilation.

I will say, though, sometimes I wish there was a smarter way to handle airflow than just cracking a window and letting in every sound from outside (and in my case, way too much pollen some days). The fans help, but they don’t always keep up when everyone’s home and using showers back-to-back. Kind of makes me think about one of those HRV systems, but that’s a whole other expense.

Energy savings are real—I’ve actually been able to turn down the thermostat more than I expected, and the house holds heat way better in winter. But like you said, it’s a tradeoff. You solve one problem and create a new one you didn’t really expect. Still worth it for me, but definitely not as “set it and forget it” as some of the sales guys made it sound.

Anyway, glad someone else is seeing the same stuff. Makes me feel less like I missed something obvious during install.

That “sealed box” vibe is so real. When I put in ultra-slim triples last fall, it was like living in a thermos overnight. I used to think my old windows were just drafty, but wow, turns out they were basically air conditioning for the neighborhood. Now, if I forget to run the bathroom fan, it’s fog city on the mirrors and sometimes on the window corners too—especially when it’s cold out.

I hear you about the HRV systems. I looked into them but the price tag made my eyes water. For now, I’m just opening windows on opposite sides for a few minutes when I can, but yeah, pollen season is rough. The energy savings are legit though—my heating bill dropped more than I expected and the place actually stays warm even when I’m stingy with the thermostat.

Honestly, I wish someone had warned me about the humidity management side of things before install. The sales pitch made it sound like “just pop them in and forget about it,” but it’s definitely more hands-on. Still, I wouldn’t go back to single panes—no way.

- Had the same thing happen here—triple panes are airtight, but that means moisture’s got nowhere to go.
- I added a cheap humidity monitor in the main rooms. It’s helped me figure out when to crack a window vs. just running the fans longer.
- Noticed if I dry laundry inside or cook a lot, the windows fog up even faster.
- HRV is pricey, yeah, but I’m keeping an eye out for rebates—sometimes the local utility offers deals.
- Energy savings are real, though. My old single panes were basically wind tunnels in winter.
- Wouldn’t go back either, but yeah, it’s not a set-and-forget upgrade.

I totally get where you’re coming from. We just put in triple glass windows last fall, and the first thing I noticed was how much quieter and warmer it got inside. But yeah, the humidity thing caught me off guard. The windows started fogging up way more than with our old drafty ones—especially after a long shower or when we had a bunch of people over. I picked up a cheap humidity sensor too and it’s honestly been a game changer. Cracking a window for a bit usually does the trick, but it’s kind of funny how “airtight” can be both a blessing and a hassle. Still, wouldn’t trade back for single panes... not after last winter.

I get that the warmth and quiet are a big improvement, but honestly, the fogging would drive me nuts. Cracking a window works, sure, but doesn’t that kind of defeat the purpose of investing in super-sealed windows? I’ve heard some folks install small ventilation systems or trickle vents to handle humidity, but that’s more money and hassle. Makes me wonder if all that “airtight” hype is always worth it, especially in older houses where airflow was never really an issue before.

You’re not wrong—airtight windows are a double-edged sword. The insulation is great, but yeah, you end up trapping all the moisture from showers, cooking, even just breathing. In older homes, you’d get that “natural” draft (aka leaky frames) that kept things dry-ish. Now, with triple glass and tight seals, you pretty much have to think about ventilation as a separate project. I’ve seen folks go the trickle vent route—doesn’t look like much, but it helps. Still, it’s a bit ironic to spend all that money sealing up the house just to poke little holes in it for air, right?

That irony isn’t lost on me. I replaced my old, drafty wood windows with triple-glazed units a few years back, and the difference in comfort was huge... but the humidity spiked almost immediately. I ended up installing a small HRV (heat recovery ventilator) system. Not cheap, but it keeps air fresh without losing too much heat. Trickle vents help, but I found they’re not quite enough if you’ve got a busy kitchen or multiple showers running daily. There’s definitely a balancing act between efficiency and indoor air quality.
