Fair points, but have you looked into cellulose insulation? It's eco-friendly too, and usually cheaper than spray foam. Curious if anyone's had long-term experience with it—does it hold up as well over time?
I've been looking into cellulose myself lately. On paper, it sounds great—eco-friendly, budget-friendly—but I'm still a bit skeptical about moisture issues long-term. A buddy of mine had it installed about five years ago, and he hasn't complained yet... but then again, he's not exactly the type to crawl around checking insulation regularly. I'd love to hear from someone who's had it for 10+ years before I fully commit.
I've used cellulose insulation on a couple of my builds over the years, and honestly, it's been a mixed bag. Had one client from about 12 years back who swears by it—no complaints about moisture or settling. But another project around the same time had some dampness creep in after about 8 years, and we ended up pulling sections out. Could've been installation quality or ventilation issues rather than the cellulose itself... but I'd say it's worth being cautious and keeping an eye on things periodically.
Interesting points—do you think the dampness issue might've been more about ventilation than the cellulose itself? I've seen similar issues pop up even with pricier insulation options when airflow wasn't properly managed. Curious if you've noticed any patterns there...
Had a similar issue last year when we renovated our attic. Initially blamed the insulation too, but turns out it was mostly ventilation. We switched to pricier foam thinking it'd solve everything—nope, still had moisture buildup. Eventually, adding a couple extra vents and improving airflow made all the difference. So yeah, from my experience, ventilation seems to be the bigger culprit than insulation type...
