You nailed it with the fit and seal making more of a difference than just adding another pane. I’ve seen the same thing on a few projects—poor installation can really undermine even the fanciest window specs. Triple glazing gets a lot of hype, but unless you’re in a super cold climate or dealing with serious noise, I’m not convinced it’s worth the premium. And yeah, condensation’s always seemed to be more about airflow and humidity than the glass itself... sometimes people overlook that.
Comparing window insulation: double vs triple glazing
I’ve run into the same thing—spent extra on triple glazing for a north-facing room, thinking it’d be a game changer. Honestly, the difference was barely noticeable compared to the double-glazed units I put in elsewhere, but the install on those was way tighter. If the frame’s not sealed right or there’s a gap, you’re just leaking money no matter how many panes you’ve got. Condensation’s always been more about how you manage indoor humidity, at least in my experience. Sometimes feels like marketing gets ahead of the real-world results...
Honestly, I’ve always wondered if triple glazing is worth the extra cash unless you’re in some crazy cold climate. I went with double glazing all around and just made sure the installers didn’t cut corners. Haven’t noticed any wild drafts or bills going up. Maybe it’s more about who does the work than the glass itself...
I hear you on the installer thing—honestly, you can have the fanciest windows in the world, but if someone leaves a gap the size of a pencil, you’ll feel it every winter. I went double glazing too and just spent extra time sealing up around the frames myself. Not glamorous work, but it made a difference. Triple glazing seems like overkill unless you’re in the Arctic or just really hate outside noise... For most homes, good double glazing and careful fitting does the trick.

I get where you’re coming from, but I’ve actually noticed a pretty big difference with triple glazing, even in a regular climate. My last place had it and the drafts were basically non-existent, plus the street noise dropped way down. Double glazing’s solid, but if you’re already doing a big reno or building new, triple might be worth the extra up front. Just my two cents—guess it depends how picky you are about comfort.
