Insulation formed by blowing nodules of inorganic fiber insulation coated with a water or other liquid activated binder in intimate contact and having a low moisture content in the just installed insulation of less than about 20 wt. percent is disclosed. The majority of the nodules have a maximum dimension of about 0.5 inch and have particles or a fiber web of a water or other liquid activated adhesive on their outer surface producing a high tack value with a very low moisture content. The insulation can be used to insulate building structures, including vertical wall cavities of buildings, without having to use any insulation securing means. The high tack value permits the sprayed-on insulation to stick to even the most stick-resistant sheathing product. The low moisture content of less than 20 wt. percent and a density of less than about 3 lbs. per cubic foot permits rapid drying of the installed installation and a lower elapsed time before the wallboard can be installed, and the insulation has a low density to produce conventional R values of at least R 13. Methods of making dry nodules coated with the reactivatable adhesive are disclosed as are methods of using the dry nodules to insulate building cavities.
