A loose-fill insulation product having irregularly shaped glass fibers is provided. The loose-fill insulation product shows improved recovery, lower thermal conductivity and requires lower product densities than prior art loose-fill insulation at equivalent fiber diameters.

Loose-fill insulation having irregularly shaped fibers

A loose-fill insulation product is provided which may be poured or blown by a consumer. The insulation is comprised of irregularly-shaped glass fibers which are comprised of two distinct glass compositions. The loose-fill insulation product may be densely packaged in a small container for consumer use, and shows improved recovery, good thermal efficiency, and low dust upon blowing or pouring.

Pourable or blowable loose-fill insulation product

A loose-fill insulation product is provided which is formed from a blend of first and second insulating materials having three-dimensional groups of fibers of different sizes and densities. At least one of the insulating materials is comprised of irregularly-shaped glass fibers comprised of two distinct glass compositions. When blended with the fibers of a standard insulation or with other irregularly-shaped fibers of different sizes, the resulting loose-fill insulation product shows improved coverage and thermal efficiency.
