Claim 9:
10. A method for forming a pourable insulating material, the method comprising steps of:
disposing glass spheres within a rotating drum;
disposing a binding material within the rotating drum;
mixing the glass spheres and the binding material during a first mixing stage to define an adhering base material, wherein a plurality of interstitial spaces defined between the glass spheres are partially occupied by the binding material;
disposing a first insulating material within the rotating drum;
mixing the adhering base material with the first insulating material to define an aggregate material;
crushing the aggregate material during a crushing stage to define an insulating base;
disposing a second insulating material within the rotating drum; and
mixing the second insulating material with the insulating base to define a homogenous form of a super-insulating material, wherein the first and second insulating materials occupy substantially all of an interstitial volume defined by the plurality of interstitial spaces.
