That doesn't mean that the material is harmful. The material is totally safe and what they say it is. I'm pretty sure you wouldn't want to choke on the dust either you dummy! he’s wearing a mask because green fiber is the blow in type insulation so obviously there will be dust particle in the air no matter what material you are using.

Bowers Sat, 11 Dec 2010 21:38:13 +0000 http://www.metaefficient.com/?p=3374#comment-141798 I'm about to have blown-in insulation added to my attic, and have reviewed pros and cons of cellulose vs. fiberglass. By logic, it seems either could infiltrate particulates, although fiberglass itself isn't dusty. (My house is on a slab foundation, with wiring and duct work in the attic.) Any future changes or maintenance will require someone to wade through the insulation. For that reason, I'll probably add more cellulose. Fiberglass contact with skin or carried on clothing presents its own problems. I have been diligent in sealing all parts of my duct and vent system to increase efficiency, and to reduce wear and tear on the system. I found that my home (built in 1977 and occupied by 2 prior families) had a lot of issues missed by my structural inspector. For instance, the plumbing chase (access to pipes between 2 bathrooms) was never enclosed...open from the attic to the foundation! Also, the soffits above my kitchen were open, leaving gaps to spaces between studs. Some of the old duct tape had dried and loosened, all of the electric boxes for ceiling lighting had small open spaces, and one duct had completely come loose from the vent. In checking where all the vents were mounted in the attic, I discovered gaps under the metal edge flanges. There were also voids along the edges of the sheet metal enclosing the cold air returns! While I have some existing cellulose insulation (not enough) , and a whole house air cleaner attached to my furnace/air-handler, I also have lots of dust. I suspect when all of these flaws are corrected prior to adding more insulation, it will greatly reduce any dust. Obviously I'll also have much improved efficiency overall. I urge you to put on a mask, use adequate light, and inspect all your duct & vent connections, as well as any other possible places for leaks. Be sure there is some fiberglass batting around your wall outlets and receptacles (behind/surrounding the boxes), and use the thin foam insulating sheets behind the wall covers of your receptacles and switchplates. While I've completed some of the "repairs" myself, I am having my insulation contractor tackle a good deal of it. He has commercial products which will perform better for some of the applications. If your ducts are in a basement, the task becomes easier. Of course a crawl space has its own challenges. Hope this helps. Possibly an energy audit might help pinpoint some problem areas. Good luck.

Is that true? Does the R-value of the paper-based product change given the humidity level of the outdoor air? or given the acquired humidity level of the product over time?

We blew in the green Cocoon type when we bought the house 6 years ago. It has cut energy bills and made us feel warmer alltogether. Now, it's wet......It sounds like it is fine on the mold resistance, from what I can tell. However I'm worried about the RU factor of what is now a considerably denser pack of what was originally a fluffy blanket of insulation.

Yes, you must wear a mask when installing this product. It is very dusty. We only placed it in our attic, used rolled fiberglass for our walls.....My concern is in the fact that we have a VERY dusty house. My computer overheated last summer and the computer expert stated that the dust build up in the computer was "gray" a dust he had never seen before. Around the light sockets, and light fixtures, a fine gray dust exists. If it can build up in my return air vent filter so that I change it sometimes 2 times a month, then it is filling my home with dust, and my family's lungs with gray dust..Any suggestions for how to keep this dust from "drifting" down from the attic into our home? I would be interested in any suggestions you may have. We used cocoon blow-in insulation when we built our home 5 years ago. Yes, you must wear a mask when installing this product. It is very dusty.
