Claims
- 1. A method of spraying or blowing a mixture of loose-fill fiberglass insulation and a polymeric redispersible powder adhesive into an open vertically extending wall cavity to be insulated, the method comprising the steps of:
- providing a said cavity to be insulated;
- providing said loose-fill fiberglass insulation;
- mixing said loose-fill fiberglass insulation together with dry said polymeric redispersible powder adhesive having a protective colloid in order to make up a loose-fill insulation mixture, said fiberglass and dry redispersible powder mixture having an amount of anti-static material less than or equal to about 0.10% by weight of the mixture; and
- spraying or blowing the loose-fill insulation mixture, including the polymeric redispersible powder having said protective colloid, together with an adhesive activating liquid into said cavity to be insulated so that the mixture is retained in said cavity in order to insulate same with insulation having a density less than or equal to about 2.5 lbs./ft..sup.3, and an R value of at least about 3.15 per inch thickness.
- 2. The method of claim 1, wherein said mixture is substantially free of said anti-static material.
- 3. The method of claim 1, wherein said mixture is totally free of said anti-static material, and said protective colloid includes polyvinyl alcohol.
- 4. The method of claim 1, wherein said redispersible powder includes a vinyl ester copolymer based resin.
- 5. The method of claim 1, wherein said redispersible powder is based on copolymers of vinyl acetate and ethylene.
- 6. The method of claim 1, wherein said mixture is from about 0.75 to 2.5% by weight said redispersible powder, and the LOI% of the installed mixture is no greater than about 3.0%.
- 7. The method of claim 1 wherein said mixture further includes an activatable color dye whose color becomes more colorful and viewable when activated by said adhesive activating liquid, said color dye being in an amount of about 0.02%-0.10% by weight of said mixture and wherein said method further includes the steps of activating said color dye with said adhesive activating liquid when said adhesive is activated by said liquid whereby said insulation when located in said wall cavity has an observable color caused by activation of said color dye.
- 8. 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.
- 9. The method of claim 8, wherein said mixture prior to said blowing is comprised of from about 97.4% to 99.40% by weight of said loose-fill fiberglass and from about 0.25% to 2.5% by weight of said redispersible powder adhesive.
- 10. A method of spraying a loose-fill fiberglass insulation mixture into a vertically extending open cavity to be insulated, the method comprising the steps of:
- providing a dry mixture of loose-fill fiber insulation and polymeric based redispersible powder adhesive, the mixture including less than or equal to about 0.10% by weight of anti-static material;
- providing an adhesive activating liquid;
- spraying the loose-fill insulation mixture together with the adhesive activating liquid into the vertically extending open cavity to be insulated so that the applied insulation is retained in the vertically extending open cavity and has a density of less than or equal to about 2.5 lbs./ft.sup.3.
- 11. The method of claim 10, wherein said redispersible powder is comprised of a protective colloid which includes a polyvinyl alcohol.
- 12. The method of claim 10, wherein said redispersible powder is comprised of copolymers of vinyl acetate and ethylene.
- 13. 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.
- 14. The method of claim 13, wherein said mixture also includes a redispersible powder having a protective colloid, and said color dye is provided in said mixture in an amount of from about 0.02% to 0.10% by weight of said mixture.
- 15. The method of claim 13, wherein said mixture includes less than or equal to about 0.10% by weight of anti-static material, so that static electricity helps to provide said mixture with a substantially uniform distribution of said color dye.
- 16. The method of claim 13 wherein said activating liquid for said adhesive and said color dye is comprised of water.
- 17. The method of claim 13 wherein said area to be insulated is an attic area.
- 18. The method of claim 7 wherein said liquid activated adhesive is a polymeric, liquid activated redispersible powder adhesive and wherein said admixture comprises from about 0.75-2.5% by weight of said polymeric, liquid activated redispersible powder adhesive and from about 97.4-99.25% by weight of said loose-fill fiberglass.
- 19. The method of claim 18 wherein said insulation when located and cured in said attic area has an LOI% no greater than about 3.0%.
- 20. The method of claim 19 wherein said LOI is from about 0.75-2.5%.
- 21. The method of claim 19 wherein said LOI is no greater than about 2%.
- 22. The method of claim 17 wherein said insulation when located and cured in said attic area has an R value of about R-19 up to R-45, a thickness of about 5-25 inches and a density from about 0.25 lbs./ft..sup.3 to about 1.5 lbs./ft..sup.3.
- 23. The method of claim 22 wherein said density is from about 0.75 lbs./ft..sup.3 -1.25 lbs./ft..sup.3.
- 24. The method of claim 13 wherein said area to be insulated is an open vertically extending wall cavity and wherein said R value is at least about 3.15 per inch thickness.
