Abstract
A glass fiber insulation product comprises irregularly-shaped glass fibers of two different glasses having differing coefficients of thermal expansion, with the irregularly-shaped dual-glass fibers exhibiting a substantially uniform volume filling nature, and providing improved recovery and thermal conductivity abilities even in the absence of a binder material.

A glass fiber insulation product comprising irregularly-shaped glass fibers having a substantially uniform volume filling nature, wherein the irregularly-shaped glass fibers comprise two distinct glass compositions with different coefficients of thermal expansion.
A glass fiber insulation product comprising irregularly-shaped glass fibers having a baseline curvature due to a dual-glass nature with a twisting, irregular rotation of the plane of curvature due to the stochastic attenuation environment, wherein the irregularly-shaped glass fibers comprise two distinct glass compositions with different coefficients of thermal expansion.
A glass fiber insulation product comprising irregularly-shaped glass fibers, the irregularly-shaped fibers having changes in rotation from one direction to the opposite direction at an average frequency of at least 0.3 occurrences per centimeter along the length of the fiber, wherein the irregularly-shaped glass fibers comprise two distinct glass compositions with different coefficients of thermal expansion.
A glass fiber insulation product comprising irregularly-shaped glass fibers having been rotated during the fiber forming process, wherein the ratio of the standard deviation of the magnitude of the rotation to the average rotation magnitude is greater than about 0.75 and the irregularly-shaped glass fibers comprise two distinct glass compositions with different coefficients of thermal expansion.
