Dealing with itchy pink nightmare in my attic

Good points about balancing intake and exhaust. When we built our place, I spent way too many weekends researching attic ventilation (fun times, right?). Ended up going with a powered fan on a humidistat because our attic was always damp - lots of shade trees around the house, and passive vents just weren't cutting it.

One thing I'd add from experience: placement matters a lot. Initially, ours was installed too close to the ridge vent, and it ended up pulling air mostly from there instead of the soffits. Once we moved it lower down the roofline, airflow improved dramatically. Also, totally agree on sealing recessed lights and attic hatches - made a noticeable difference in comfort downstairs.

Still, powered fans aren't magic bullets. If your insulation is thin or patchy (like ours was at first), you'll still have issues. We beefed up insulation after installing the fan, and that combo finally got things under control. Like you said, it's all about figuring out what your attic specifically needs... trial and error sometimes.

"placement matters a lot. Initially, ours was installed too close to the ridge vent"

Good catch on placement - I learned that lesson the hard way too. Had a client's attic fan pulling air straight from the ridge vent...didn't help at all until we shifted it down. Definitely a trial-and-error kinda thing.

Definitely been there with attic fan placement - it's surprising how much a small shift can change the airflow. I had a similar issue with a client's attic remodel. We initially placed the fan thinking it'd be most effective right near the ridge vent, but it just ended up pulling air from outside instead of circulating properly. After moving it lower and adding some well-placed insulation baffles, things improved dramatically. While you're dealing with that itchy pink stuff anyway, might as well double-check your insulation channels and make sure they're guiding airflow correctly from soffits to ridge. It's one of those subtle details that really pays off in comfort (and energy bills) down the line...

Good points on the insulation channels - those baffles really do make a difference. One thing I'd add from experience: when you're adjusting fan placement, it's worth doing a quick smoke test to visualize airflow. Just grab one of those cheap smoke pencils or even incense sticks, and hold it near your soffit vents and fan intake. You'll see exactly how air moves through the attic space, and it can save you from guessing or having to redo things later.

Also, if you're already knee-deep in itchy fiberglass (been there, done that...ugh), consider wearing disposable coveralls and taping your sleeves and ankles shut. It sounds overkill, but trust me, you'll thank yourself later when you're not itching for days afterward. And don't forget a good respirator mask - not just a dust mask - to keep those tiny fibers out of your lungs.

Small comfort tip: baby powder helps get rid of fiberglass itchiness after you're done working. Sounds weird, but it actually works pretty well.

"Small comfort tip: baby powder helps get rid of fiberglass itchiness after you're done working. Sounds weird, but it actually works pretty well."

Wish I'd known about the baby powder trick sooner... spent way too many evenings scratching like crazy after attic work. Another thing that helped me was taking a cold shower first - hot water opens your pores and makes the itch worse. Cold water isn't fun, but it beats itching all night. Also, seconding the respirator advice; those cheap dust masks just don't cut it with fiberglass.

Wish I'd seen this thread before my insulation project last summer. I spent days itching and trying all kinds of weird remedies (vinegar, anyone?). Funny enough, I found duct tape actually helped by gently dabbing the itchy spots - sounds kinda sketchy, but it lifted off some fibers.

"Cold water isn't fun, but it beats itching all night."

Totally agree on cold showers though...painful, but worth it. Maybe next time I'll brave the baby powder route, lol.

I feel your pain on the vinegar thing...tried that once myself and just ended up smelling like a salad for days. Honestly, duct tape isn't the worst idea I've heard - fiberglass fibers are tiny and clingy, so it makes sense that something sticky might lift them off. Still, I'd be careful not to irritate the skin even more.

As for baby powder, I'm skeptical. It might soothe temporarily, but I doubt it'll actually remove the fibers. If you ever have to do this again (hopefully not anytime soon), I've found that wearing long sleeves taped at the wrists and ankles helps a ton. Sure, you look ridiculous, but it beats itching for days afterward. Also, rinsing off with cold water right after exposure is definitely your best bet - warm water opens pores and lets those nasty fibers dig in deeper.

Anyway, live and learn, right? At least now you've got some battle-tested strategies for next time...if there ever is one.

"Honestly, duct tape isn't the worst idea I've heard - fiberglass fibers are tiny and clingy, so it makes sense that something sticky might lift them off."

Duct tape, huh? Can't say I've tried that one myself, but I can see the logic behind it. Fiberglass is nasty stuff, and once it's on you, it's like glitter - just keeps showing up everywhere for days. I've had my fair share of attic adventures, and honestly, the cold water rinse is probably the best advice here. Learned that one the hard way after a hot shower turned me into a walking itch-fest for a week.

Baby powder...yeah, I'm with you on being skeptical there. Seems like it'd just mask the problem temporarily. I've heard some folks swear by using lint rollers - same sticky logic as duct tape, but maybe gentler on the skin? Haven't tried it myself though, so can't vouch for it.

One thing I've always wondered about is those disposable painter's suits. They're cheap enough, and you could just toss them afterward. Anyone here ever given those a shot for fiberglass work? Seems like they'd be breathable enough to avoid overheating, but still keep the fibers off your skin. Or would they tear too easily crawling around tight attic spaces?

Either way, definitely agree on the taped sleeves and ankles. Might look goofy, but I'll take goofy over itchy any day.

Or would they tear too easily crawling around tight attic spaces?

I've tried those disposable painter suits before - honestly, they're decent for quick jobs, but crawling around tight attic spaces usually leaves me with tears and gaps anyway. I'd stick with taped sleeves and ankles like you mentioned... goofy look beats itchy misery every single time.

I've been down that road... those disposable suits are great in theory, but one sharp nail or splinter and you're toast. Agree with this:

"goofy look beats itchy misery every single time."

Better to look like a duct tape mummy than scratch fiberglass bits off yourself for days.

Totally get the duct tape mummy vibe - been there, done that. Disposable suits are decent for quick jobs, but yeah, one snag and you're itching like crazy. Here's a trick I've learned the hard way: layer up. Thin long-sleeved shirt underneath, disposable suit on top, then duct tape cuffs and ankles. Sounds like overkill until you've spent an evening pulling fiberglass shards out of your skin with packing tape (ask me how I know).

Also, goggles and a respirator are non-negotiable. Fiberglass in your lungs or eyes is no joke... trust me on this one.

But honestly, if you're up in the attic regularly, why not consider upgrading to something less miserable? Spray foam insulation or cellulose might cost more upfront but saves you from the pink nightmare down the line. Plus, better energy savings and fewer itchy evenings make it worth every penny.

Good points, but spray foam isn't always budget-friendly - quotes I got were pretty steep. Instead, I stapled up some breathable fabric as a barrier. Not perfect, but way less itching and didn't break the bank. Just throwing that out there...

Breathable fabric helps with the itch factor, but keep an eye on moisture buildup behind it. If humidity gets trapped, you might run into mold issues down the line... Maybe consider adding some venting if you haven't already?

Breathable fabric can help, sure, but honestly I'd be cautious about relying too heavily on it as a moisture barrier. In my experience, fabric alone - even breathable types - won't adequately handle attic humidity. Proper insulation paired with a dedicated vapor barrier is usually more effective at preventing moisture buildup. Venting's good advice, but sometimes it's not enough on its own. Might be worth checking your attic's airflow and insulation setup to tackle the root cause rather than just symptoms...

Good points here. I've seen plenty of cases where people thought breathable fabric would solve moisture issues, only to find mold or dampness creeping back in after a season or two. Usually, it's because the underlying airflow isn't properly addressed. Have you checked if your soffit vents are clear and actually pulling air through the attic space? Sometimes insulation gets stuffed too close and blocks them without anyone noticing...

"Sometimes insulation gets stuffed too close and blocks them without anyone noticing..."

Exactly what happened in my attic. Previous owner crammed insulation right up against the soffit vents - took me forever to figure out why moisture kept returning. Clearing that space made a huge difference. Worth checking out.

Had the same issue when I first moved in - previous owner had insulation jammed right up against the soffit vents. Took me a while to realize why the attic was always damp. Ended up installing those foam baffles between the rafters to keep insulation clear of the vents. They're cheap, easy to put in, and solved the moisture problem completely. Might be worth looking into if you haven't already...

"Ended up installing those foam baffles between the rafters to keep insulation clear of the vents."

Yeah, those foam baffles are a lifesaver. I put them in last summer after noticing condensation building up on the attic ceiling. Honestly, I was skeptical at first - seemed too simple to actually work - but it made a huge difference. Did you notice any improvement in your home's overall temperature regulation after installing them? I'm curious if others found it helped with heating and cooling bills too...

Foam baffles definitely help with ventilation, but honestly, I haven't seen them make a huge dent in heating or cooling costs. In my experience, they're more about preventing moisture buildup and protecting insulation from mold or damage. If you're really looking to improve temperature regulation, you might want to check your attic insulation depth or consider sealing air leaks around recessed lights and attic hatches - those small gaps can add up surprisingly fast...

Totally agree about the foam baffles - definitely more about moisture than temperature. When I moved into my place, the attic was a mess of old insulation and random gaps everywhere. First thing I did was seal up around the attic hatch and recessed lights with some caulk and weatherstripping. Took maybe an afternoon, tops. After that, I added another layer of blown-in insulation to get it up to recommended depth (around 15-18 inches in my area). Honestly, that made a noticeable difference in comfort, especially upstairs.

One thing I'd add: check around your chimney or vent pipes too. I found a pretty big gap around my chimney flashing that was letting in drafts and moisture. Sealed it up with some high-temp caulk, and it helped a lot. It's those sneaky little spots you don't think about that really add up.
