using open cell spray foam trimmings as loose-fill insulation any experience or data?

[Th3rmoPro]

So, I recently chatted with a spray foam contractor, and he gave me a few bags full of Demilec open cell spray foam trimmings. He suggested I might be able to just toss them out on my attic floor like loose-fill insulation. At first, it sounded kind of cool, but honestly, I haven't been able to find much solid info online to see if that would actually work

Has anyone out there tried using open cell trimmings for insulation this way? I'm curious abt how well it performs. Or does anyone have any reliable info about using leftover spray foam like it's loose-fill? I would really appreciate any tips or expereinces you might have

Yeah, no tossing open cell spray foam trimmings around like loose fill is a half baked idea at best, spray foam works because it seals. When it's shredded up and loose, it has lost most of what made it good insulation in the first place, you'll be better off using proper blown in cellulose or fiberglass

I ran into the same idea when renovating my garage, the contractor left me a pile of open-cell trimmings and suggested using them like loose-fill. I did some digging and found they don't perform the same way once cut, they lose a lot of their air-sealing properties and can absorb moisture if not properly contained. Might be okay in super dry attics, but I ended up using them in garden beds instead. Do check the local code before tossing them up there!

Wow, I'm amazed that contractors left you with a pile of garbage and claimed it would do something it doesn't. Here's some advice. Don't hire those contractors again, and find ones that can give you a proper way to insulate your attics.

yep, OP's better to get a proper product. Blown in fiberglass or cellulose is inexpensive, easy to install, and designed for exactly what you're trying to do. It's the only way to make sure you get a safe, effective, and code compliant insulation job
