ABSTRACT:
A insulation device includes an enclosure defining a cavity which is filled with a binderless, loose, discrete, divided insulation material. An uncured binder is homogeneously dispersed through the insulation filling material prior to installing the insulation material in the enclosure. The binder is cured after the insulation material is installed in the cavity to prevent the shifting or settling of the insulation material within the cavity. The insulation device can be made by forming an opening into the cavity of the enclosure, injecting binderless, loose, discrete, divided insulation material into the enclosure cavity and concurrently applying an uncured binder on the insulation material as it is being injected into the enclosure cavity to homogeneously distribute the uncured binder throughout the insulation material being injected into the enclosure cavity, and closing the opening of the enclosure. Alternatively, the uncured binder is mixed with the insulation material before the insulation material is injected into the enclosure cavity.
