Abstract
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 the majority of the nodules have 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 an insulation on the substrate.

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.
