I am building a new house and was considering using blown-in cellulose insulation in the walls... you know... the type that has an adhesion agent added to adhere to the wall. Several people have told me that over time (years?) that the insulation will settle. The manufacture of the cellulose insulation says it will not settle. Who's right?

Older methods of blowing cells led to a lot of settlement with loose fill. Using it wet and glue added will not allow that. Thje added moisture creates a time factor in construction schedule for drying though or it can cause a lot of trouble.

Blow dens packs cellulose dry or check chopped fibreglas out.

You could also look into Corbond sprayed foam for the best insulation package.

Thanks Piffin,

I will have full control over when the drywall will be installed after the insulation is installed. The insulation installer says to allow the insulation to dry about a day... what would you recommend? three days, a week, two weeks?
