Haha, your denim insulation story made me chuckle—been there, done that, got the moldy t-shirt. 😅
A few years ago, I got super excited about hemp insulation (because, you know, sustainability and all that jazz). It sounded amazing on paper—eco-friendly, breathable, and supposedly moisture-resistant. Well, turns out "moisture-resistant" doesn't mean "flood-proof." After one particularly rainy spring, my basement walls started smelling like a damp barnyard. Not exactly the cozy vibe I was going for...
Ended up tearing it all out and going back to good ol' rigid foam boards and vapor barriers. Not as exciting or Instagram-worthy, but hey, dry walls beat trendy walls any day.
Totally agree with you on mineral wool though—it's been a lifesaver on a few projects. It's pricier, sure, but it checks a lot of boxes: moisture-resistant, fireproof, and still eco-friendly enough to ease my guilty conscience. Plus, it's way easier to handle than fiberglass (no itchy arms for days afterward).
Anyway, just wanted to say you're definitely not alone in the eco-insulation fails club. Sometimes we have to learn these things the hard way... at least it makes for good stories later, right? 😉

Haha, I feel your pain on the hemp insulation. Had a similar experience with cork panels—great eco-cred, but after a wet winter, my basement smelled like old wine barrels. Mineral wool's been solid though, definitely worth the extra bucks.
That's interesting about the cork panels—I hadn't thought about that wet barrel smell issue, but it makes sense. Mineral wool is definitely reliable, but if you're still considering eco-friendly options, have you looked into rigid foam boards made from recycled materials? They're moisture-resistant and hold up pretty well in damp conditions. Might be a solid compromise between sustainability and practicality, especially if your basement tends to get damp regularly. Just something worth considering...
Rigid foam boards from recycled materials are definitely a solid suggestion—I've used them myself in a basement reno and they held up pretty well. One thing to keep in mind, though, is installation. If your basement walls aren't perfectly even (mine definitely weren't...), you'll need to spend extra time sealing gaps and seams with waterproof tape or caulking to prevent moisture infiltration. Otherwise, water can sneak behind the panels and cause hidden mold issues down the line.
Also, since we're talking eco-friendly options, has anyone tried hemp-based insulation panels? I've read they're naturally resistant to mold and pests, plus they're breathable enough to handle humidity fluctuations. Curious if they'd hold up in more extreme damp conditions like occasional flooding or heavy moisture buildup...
Rigid foam boards are great, but you're spot-on about uneven walls. I spent an entire weekend wrestling with caulk and waterproof tape—felt like I was sealing up the Titanic. As for hemp-based insulation, I haven't tried it personally, but a buddy of mine did in his cabin. He said it handled humidity pretty well, but after a minor flood, it took forever to dry out completely. Might be better suited for dampness rather than actual flooding scenarios...
