On the show I watched last night Mike was doing blown-in cellulose insulation. I've done it a couple times but only on horizontal (attic/over garage) applications. This crew was blowing it onto walls pre-drywall, then shaving off the excess flush to the studs. Is there some sort of binder/additive that is added to make it stick?

The water makes it stick. wet paper is naturally sticky, think spit wads.

Water makes it stick, water and air make it "fluid" to wrap around pipes, cable, boxes, etc. It's mainly recycled newspaper with flame retardants added. Supposed to be a very environmentally friendly option as opposed to fiberglass.- Chris.Comment

My w/w friend did some remodeling in his 150 yr old house last summer. The stuff you are talking about is 10 times more efficient than fiber glass. It fills all the cracks and voids that f/g has to be packed around. Its a hoot to watch them; spray it on, over the tops of the studs and all, then use an electric roller/shaver to bring it level to the studs. He had some blown lose in the attic, about 15"'s worth. Great stuff! What would have taken a couple of days was done in one morning.RuffSawn

There is a company here doing the same sort of thing with ground up denim (yeah, levi's et. al.). Same process, same concept. Fire retardent, fills the voids, they sweep up the stuff they trim off and reuse it. They buy a lot of the material from denim factories as waste and recycle it.
Do any of you watch Holmes on Homes. They use a lot of foam insulation, blue in color that they spray on. I cant find any information about it in this part of the country, but it looks like a **** of a good productDennis K Howard

I've used the denim batts and they are very good. it insulates sound very well, is somewhat easy to install, environmentally friendly, and most importantly NO ITCH!!
expanding foam is really good insulation because it creates a complete seal in the wall cavity.Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas EdisonComment

Foam insulation
I have a friend who has a motorcycle shop. He is quite tight in the pockets.Took packing peanuts from shipping boxes put them in attic over garage. year or two later they were all blown into one corner.saved a doller made a mess.The bitterness of poor quality lingers long after the sweetness of low cost is forgotten!Comment

How does this stuff compare in price to fiberglass batts? I need to do my garage shop ceiling in the next couple of weeks and am trying to decide what to put up there.GaryComment

Fiberglass batts are the cheapest option but have the minimum performance of what has been mentioned.
anything that is sprayed in is better then batts because it fills every crevice so you get less air intrusion. you also don't have the paper backing to feed mold. the denim material is similar performance to fiberglass batts, costs twice as much, but has no itch and has significantly better sound deadening.Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas EdisonComment
