I’ve always wondered about fiberglass mesh in high-sun spots. Mine started to get brittle after a year, but it was the cheap stuff from the hardware store, so maybe that’s on me. Stainless is pricey, but I get why folks want the peace of mind. With ducting, I did something similar—used leftover foam pipe wrap and it’s held up fine so far, though I’m in a pretty humid area. Ever had issues with critters chewing through the mesh? That’s been my main headache, especially in spring when everything’s looking for a way in...

- Fiberglass mesh in direct sun is basically a countdown to disappointment. Even the “good” stuff gets brittle after a couple seasons, especially if you’re anywhere with real UV. I’ve seen it crumble just from being looked at funny.
- Stainless is expensive, yeah, but you’re paying for not having to redo it every year. I’ve tried the “middle ground” aluminum mesh too—lasted longer than fiberglass but still got chewed up by squirrels. They treat it like an appetizer.
- Critters are relentless. Mice and chipmunks will chew through almost anything that isn’t metal. I’ve even seen them gnaw through foam pipe wrap like it’s a snack bar. If you’re in a humid area, watch for mold on that foam too—had a customer call me out once because their “insulation” turned into a science experiment.
- For ducting, I’m skeptical about foam wraps holding up long-term if there’s any chance of condensation or leaks. Once water gets in, it’s game over—mold city and then the critters move in for the buffet.
- If you want peace of mind and less maintenance, stainless mesh is the way to go. Pricey up front, but you’ll forget about it after install (unless you like climbing ladders every spring).
- One trick: double up on mesh at entry points—stainless outside, cheap stuff inside as a backup. Not foolproof, but slows down the determined ones.
Honestly, nothing’s 100% critter-proof if they’re motivated enough...but stainless at least makes them work for it. And yeah, springtime is always when they get creative—had one raccoon rip off an entire vent cover once just to see what was inside.
Yeah, critters are just on another level when they want in. I’ve seen mice squeeze through gaps I didn’t even know existed, and squirrels will chew through almost anything if they’re determined. Stainless mesh really is the only thing I’ve seen hold up long-term, even if it stings a bit at checkout. The double mesh trick is smart—gives you a little more time before they break through.
I get what you mean about foam pipe wrap too. Once it gets wet, it’s basically a buffet for mold and critters. Had to pull out a bunch of soggy insulation last year—nasty job. Honestly, you’re doing the right thing thinking ahead about all this. It’s a pain now, but way less hassle down the road. Spring’s always the worst for surprises... seems like every year there’s a new “creative” entry point to deal with. Hang in there, you’re not alone in the battle!
Had a possum chew through my vent stack once—never thought I’d see the day. Stainless mesh saved me a second round, but yeah, that stuff’s not cheap. I’ve found even the tiniest gap behind a pipe can turn into a critter highway if you’re not careful. Foam wrap’s just asking for trouble in damp spots, especially under a rig. Every spring, I brace myself for what I’ll find under the floor... sometimes it’s just a mess of shredded insulation and sometimes it’s worse. Wouldn’t trade the dry loo setup, though—less plumbing, fewer leaks, and way less to attract the wildlife.
That possum story made me wince—I had a squirrel chew through a flex duct once and it was a whole ordeal. You’re spot on about foam wrap; it’s basically critter bait if there’s any moisture. Stainless mesh is pricey, but honestly, I’d rather pay upfront than deal with another infestation. The dry loo’s been a game changer for me too—less plumbing means less stress. Spring inspections are always a gamble, but at least there’s less to go wrong now.
