Double vs triple glazing for energy efficiency - worth the upgrade?

We just did triple glazing last fall and, honestly, I was surprised how much warmer the living room felt right away. Our old double panes weren’t terrible but you could still feel the chill sitting near them. Not cheap, but comfort-wise, I’d do it again.

That matches my experience too. We did triple glazing in our bedroom two winters ago and it made a noticeable difference - no more drafty corners at night. The price stung a bit, but I’d say the comfort is worth it, especially during cold snaps.

Triple glazing definitely sounds tempting, especially when you mention the drafty corners disappearing. I’m curious though - did you notice any change in your heating bills, or was it more just about comfort? I’ve got double glazing throughout and it helped a ton with noise, but our old Victorian place still feels chilly in spots. Sometimes I wonder if the extra pane is worth the extra pain (in the wallet, I mean).

Did you have to do anything special with the frames or was it a straight swap? I keep hearing horror stories about older windows needing extra work. And honestly, did you notice any difference in summer, or is it mainly a winter thing? My partner thinks I’m just looking for an excuse to avoid another DIY project...
