"Definitely worth considering breathable insulation options like cellulose or mineral wool if you're working with an older structure."
Good advice overall, but I wouldn't completely rule out spray foam. Had similar issues initially, but realized later the condensation was more about inadequate ventilation than the foam itself. Once I added proper vents and improved airflow, things balanced out nicely. Older homes do need to breathe, sure...but sometimes it's about tweaking ventilation rather than ditching airtight insulation altogether. Just my two cents from wrestling with my own historic fixer-upper.
Interesting perspective on ventilation—I hadn't thought about that angle much. I'm currently knee-deep in my first renovation (a charming but drafty 1920s bungalow), and I've been leaning toward mineral wool after hearing a few horror stories about moisture issues with spray foam. But your experience makes me reconsider a bit...maybe it's less about the insulation itself and more about how air moves through the house?
Did you find it tricky or expensive to retrofit better ventilation into your older home? My biggest concern is getting it right without busting my budget or losing too much of the original character. Seems like balancing modern efficiency with historical charm is always a tightrope walk, haha.
Retrofitting ventilation doesn't have to break the bank—I found it manageable by tackling one room at a time. Installed discreet vents behind crown molding, kept original charm intact. Curious if you've looked into heat recovery ventilators (HRVs)...might strike that balance you're after.

Definitely agree on the HRV suggestion—installed one last year and noticed a solid improvement in air quality without losing much heat. Bit pricier upfront, but energy savings add up over time. Worth considering.
HRVs sound great, and I totally get why people swear by them, but honestly, from my experience, they're not always the silver bullet solution. I'm in the middle of renovating my first home (built in the 70s, drafty as heck), and we debated forever about HRVs vs. insulation upgrades. Ended up going heavy on insulation instead—spray foam in the attic, sealing gaps around windows and doors, that sorta thing—and it's been a total game changer.
I'm not knocking HRVs completely, because yeah, fresh air without losing heat sounds awesome. But if your house is already leaking air like mine was, installing an HRV feels kinda like trying to fill a leaky bucket. Sure, you're recovering some heat, but you're still losing a ton through all those tiny gaps and cracks. For us, sealing and insulating made way more sense financially and practically. Plus, once we tightened things up, our heating bills dropped noticeably—even without adding an HRV into the mix.
Another thing to consider: maintenance. My neighbor put in an HRV unit last winter and says it's great but admits it's a bit of a pain cleaning filters regularly and dealing with occasional mechanical hiccups. Maybe that's no biggie for some folks, but personally, I'm all about low-maintenance solutions whenever possible.
Anyway, just my two cents from someone who's right in the thick of it—your mileage may vary depending on your home's age and condition. But don't overlook good old-fashioned insulation and sealing before jumping straight into pricier tech solutions...might save yourself some headaches (and cash) in the long run.
