Any time you’re going to be around a large amount of particulates suspended in the air, it isn’t a bad idea to wear a mask. Even though the material itself isn’t toxic, exposing yourself to it in large amounts in a confined space for long periods of time can give you problems, causing fluid buildup in your lungs and other irritating and potentially dangerous conditions. Think about it like this: you can immerse yourself in pure water and it isn’t toxic at all, but without some method of breathing you’re not going to want to stay under very long or you’ll die.

We just blew this stuff into my attic and it does tend to end up getting all over the place, but it doesn’t seemn toxic (no weird smells, no dead animals or children).

I bought a house in Raleigh in Nov.2008 and they used this product in it. It has a great noise reduction quality as my townhouse has neighbors on both sides both with kids and one with a huge surround sound system and I rarely even hear anything from them. Green Fiber also has a website where they build test structures and then burn them to the ground. The first is one with no insulation and it burns to collapse very quickly, the second is one with bat insulation and takes mush longer to collapse, and the 3rd is one with green fiber which stays standing for quite a bit longer. Another advantage to this product over blown insullation is that it has been rated not to settle (a common problem with blown insulation in walls where over time the fibers compress leaving the upper portion of the wall uninsulated).

You should always wear a mask when blowing insulation; irregardless of what it is made from. Any airboarn particulates can cause irritation to the sinuses and lungs.
I’ve heard of people with respitory problems from working in cotton mills.
To make it fire resistant it is treated with a chemical; I don’t remember what but they have been doing this with blown in cellulose insulation for years.

LOL I agree w/ D Puetz. Also how can something derived from paper be fire resistant??

Good question D Puetz -

According the GreenFiber website:
GreenFiber Cocoon Insulation is listed/regulated by OSHA, Cal/OSHA, and ACGIH as “Particulates Not Otherwise Classified” or “Nuisance Dust.”

Therefore, installers may choose to wear a mask if the environment is generally dusty, but the insulation doesn’t contain any substances that require specific protective apparel.

Right below your statement: “Cocoon Insulation is non-toxic and contains no fiberglass or asbestos – which avoids exposing users to irritants, and requires no protective clothing or masks for installation.” is a picture of an installer wearing a protective mask…..so which do we believe ???? The statement or the picture?
