We are building a new house, and we are looking into Cellulose. We are trying to find people who have it, and what they think of it.

What everyone is saying about the settling is absolutely true! Not only does it settle in ceilings but also when blown into walls. I've seen it first hand, when a builder waits a day or so to sheetrock and I've been in a house after its been blown w/ cellulose....half of the cellulose in between the studs has slid down, leaving HUGE gaps.
Some other points to consider:
Cellulose is mixed w/ water. It takes a very experienced installer to get the mixture right, otherwise you've got a soggy mess in your walls.
Also, over time the chemicals used to make cellulose (fire retardant stuff) break down and just don't do their job......
I would use a half inch of polyurethane foam on exterior walls w/ a batt on top of that.....blow fiberglass in your attic...

Cellulose does work. The only problem is after a couple years, it settles and loses R-value. Insulation works due to air space in it. Thats why you do not compress batts. When it settles, the air is gone. On new construction, I would advise batts. For use after the home is built, cellulose is much easier to install.

I have owned homes with cellulose and have installed it in other homes. I prefer fiberglass insulation because it does not sag or settle like cellulose.

I agree with sensible. We bought our 14 yr old house two years ago and there is no way the insulation is still 18" deep like it supposedly was when installed, probably closer to a foot. I have also heard that it can make your house dusty if the ceiling/attic interface is not well sealed. Our house does seem dusty, but it may just be the power of suggestion.

I have had cellulose insulation in my home and have used it in home I have built. Honestly if you plan to stay in your new home for years I would not use it. It does settle dramaticly and if you live in a high humid area it will settle even faster. I just used Icynene spray foam insulation in my last home I built for myself. I live in vermont and the house was amazingly draft free and warm.

I would NEVER have that crap in any house of mine. Other than that it settles and the breeze coming in from the soffit/eave vents will blow it around, like snowdrifts, and its powdery fine dust will end up in every room below it, it is HELL to work in if you have to fix or install anything in the attic. Bite the bullet, go with 'batts' of rolled insulation; don't cover up any electrical junction boxes or the tops of any light fixtures, exhaust fan, etc....much easier to accomplish than with blown-in insulation.

We like it. We built our house ourself and it's nicer to have somebody come blow in the insulation rather than to deal with fiberglass batts. Our house is cozy warm without the cold spots you can get with rolled insulation.

We blew it in to add to the pink stuff, We've had dust problems ever since. Will never use again.
