The invention claimed is: 1. A method of forming a nodular insulation material suitable for installation in a cavity, comprising: propelling fibrous nodules at a substrate, wherein the fibrous nodules are formed from inorganic fibers, wherein a majority of the nodules has a maximum dimension of about one-half inch, and contacting the nodules while the nodules are being propelled, with a solution comprising water and a water soluble binder to produce coated nodules, wherein the coated nodules form a just installed insulation on the substrate, the just installed insulation having a moisture content of less than about 2 pounds per standard wall cavity and and comprising an additive effective for increasing the thermal insulation performance of the insulation, the additive including an infrared radiation blocking agent. 2. The method of claim 1, wherein when the just-installed moisture content of the insulation is less than about 1.5 pounds. 3. The method of claim 1, wherein the additive is present in an amount of at least about 8 wt. percent. 4. The method of claim 2, wherein the nodules are propelled at a cavity to form the insulation in the cavity and wherein the additive is present in an amount of at least about 8 wt. percent. 5. The method of claim 4, wherein some of the nodules contact and adhere to at least one wall of the cavity, and some of the nodules contact and adhere to other nodules, to form the insulation. 6. The method of claim 1, wherein the insulation has an R value from about 12 to about 16 after drying. 7. The method of claim 1, wherein the insulation has a density of about 3 PCF or less after drying. 8. The method of claim 1, wherein the inorganic fibers comprise glass fibers. 9. The method of claim 1, wherein the nodules comprise glass fibers bonded together with a cured resin at one or more locations where two or more of the glass fibers cross one another. 10. The method of claim 1, wherein at least about 70 percent of the coated nodules have a maximum dimension of one-quarter inch. 11. The method of claim 1, wherein at least about 80 percent of the coated nodules have a maximum dimension of one-half inch. 12. The method of claim 11, wherein at least about 90 percent of the coated nodules have a maximum dimension of one-half inch. 13. The method of claim 1, wherein the water soluble binder comprises a partially hydrolyzed polyester oligomer. 14. The method of claim 1, wherein the binder is present in the insulation in an amount of less than about 6 wt. percent, on a dry solids basis. 15. The method of claim 1, wherein the binder is present in the insulation in an amount of less than about 4 wt. percent, on a dry solids basis. 16. The method of claim 10, wherein the inorganic fibers have an average fiber diameter of 3 microns or less. 17. The method of claim 1, wherein the substrate at which the fibrous nodules are propelled comprises a surface of a wall, floor or ceiling cavity. 18. The method of claim 17, wherein the wall, floor or ceiling cavity is an open cavity. 19. The method of claim 1, wherein the distance the nodules are propelled is selected to achieve a predetermined density of the nodular insulation material. 20. The method of claim 1, wherein the nodules are propelled from a nozzle, and the distance between the nozzle and the substrate is selected to achieve a predetermined density of the nodular insulation material. 21. The method of claim 1, wherein the flow rate of the fibrous nodules propelled at the substrate is from about 10 to about 50 lbs/mm. 22. The method of claim 16, wherein the flow rate of the fibrous nodules propelled at the substrate is from about 20 to about 30 lbs/min. 23. The method of claim 1, wherein the fibrous nodules comprise the additive effective for increasing the thermal insulation performance. 24. The method of claim 2, wherein the insulation has a density of about 3 PCF or less after drying. 25. The method of claim 23, wherein the additive effective for increasing thermal insulation comprises an infrared radiation blocking agent in an amount of at feast about 8%. 26. The method of claim 25, wherein the infrared radiation blocking agent comprises B2O3. 27. The method of claim 1, wherein the fibrous nodules comprise a fire retardant. 28. The method of claim 1, wherein the insulation formed on the substrate comprises a fire retardant.
