Method of installing insulation with dry adhesive and/ or cold dye, and reduced amount of anti-static material

A method of spraying or blowing loose-fill fiberglass insulation into a vertically extending open cavity, the method comprising the steps of:

• providing the vertically extending open cavity to be insulated;
• providing a dry mixture of loose-fill fiberglass and polymeric redispersible powder adhesive, said mixture being substantially free of anti-static material;
• and
• spraying or blowing said loose-fill insulation mixture together with an adhesive-activating liquid into the vertically extending open cavity so that the mixture is retained in the cavity in order to insulate the open cavity with insulation having a density of less than or equal to about 2.5 lbs./ft.sup.3.

A method of spraying or blowing a mixture into an area to be insulated, said mixture including an effective amount of:

• a) loose-fill fiberglass insulation,
• b) a dry powdered liquid activated adhesive,
• c) a liquid activated, dry powdered color dye, and
• d) a liquid capable of activating said adhesive and said color dye,
• wherein, said dry powdered color dye has a color which becomes more colorful and viewable when activated by said activating liquid, the method comprising the steps of:
• providing the area to be insulated;
• providing an unactivated admixture which includes said effective amount of said loose-fill fiberglass insulation, said dry powdered liquid activated adhesive, and said dry powdered color dye;
• and
• spraying or blowing said admixture together with said effective amount of said adhesive and color dye activating liquid into said area to be insulated, thereby
• activating said adhesive and said color dye such that said activated mixture forms in said area a layer of fiberglass insulation having a density of less than or equal to about 2.5 lbs./ft..sup.3 and an R value of at least about 2.7 per inch thickness and an observable color caused by activation of said color dye, and wherein
• the formation of said observable color caused by activation of said color dye indicates that said adhesive activating liquid was present in said admixture during said spraying or blowing of said admixture into said area.
