Unbonded loosefill insulation

An improved unbonded loosefill insulation material comprising a multiplicity of tufts and a plurality of voids between the tufts, the tufts having a tuft density;

• wherein the tuft density of the tufts of the improved unbonded loosefill insulation material is less than the tuft density of the tufts in conventional unbonded loosefill insulation material, thereby providing the improved unbonded loosefill insulation material with a higher insulative value than conventional unbonded loosefill insulation material.

An improved unbonded loosefill insulation material comprising a multiplicity of tufts and a plurality of voids between the tufts, the tufts having an outer surface including a plurality of irregularly-shaped projections;

• wherein the tufts of the improved unbonded loosefill insulation material have more irregularly-shaped projections than the tufts in conventional unbonded loosefill insulation material, thereby providing the improved unbonded loosefill insulation material with a higher insulative value than conventional unbonded loosefill insulation material.

An improved unbonded loosefill insulation material comprising a multiplicity of tufts and a plurality of voids between the tufts, the tufts having an outer surface formed from a plurality of irregularly-shaped projections, the irregularly-shaped projections having a plurality of hairs extending therefrom;

• wherein the tufts of the improved unbonded loosefill insulation material have more hairs extending from irregularly-shaped projections than the tufts in conventional unbonded loosefill insulation material, thereby providing the improved unbonded loosefill insulation material with a higher insulative value than conventional unbonded loosefill insulation material.

An improved unbonded loosefill insulation material comprising a multiplicity of tufts and a plurality of voids between the tufts, the tufts having tuft gaps within the tufts, the tuft gaps having a size;

• wherein the size of the tuft gaps within the tufts of the improved unbonded loosefill insulation material are larger than the size of the tuft gaps within the tufts of conventional unbonded loosefill insulation material, thereby providing the improved unbonded loosefill insulation material with a higher insulative value than conventional unbonded loosefill insulation material.

An improved unbonded loosefill insulation material comprising a multiplicity of tufts and a plurality of voids between the tufts, the tufts having tuft gaps within the tufts, the tuft gaps having a gap frequency of occurrence;

• wherein the gap frequency of occurrence of the tuft gaps within the tufts of the improved unbonded loosefill insulation material is greater than the gap frequency of occurrence of the tuft gaps within the tufts in conventional unbonded loosefill insulation material, thereby providing the improved unbonded loosefill insulation material with a higher insulative value than conventional unbonded loosefill insulation material.

An improved unbonded loosefill insulation material comprising a multiplicity of tufts and a plurality of voids between the tufts, the tufts having tuft gaps within the tufts, the tuft gaps having a gap distribution;

• wherein the distribution of the tuft gaps within the tufts of the improved unbonded loosefill insulation material is more even than the distribution of the tuft gaps within the tufts in conventional unbonded loosefill insulation material, thereby providing the improved unbonded loosefill insulation material with a higher insulative value than conventional unbonded loosefill insulation material.

An improved unbonded loosefill insulation material comprising a multiplicity of tufts and a plurality of voids between the tufts, the tufts having tuft gaps within the tufts, the tuft gaps having a gap distribution;

• wherein the distribution of the tuft gaps within the tufts of the improved unbonded loosefill insulation material is more even than the distribution of the tuft gaps within the tufts in conventional unbonded loosefill insulation material, thereby providing the improved unbonded loosefill insulation material with a higher insulative value than conventional unbonded loosefill insulation material.

An improved unbonded loosefill insulation material comprising a multiplicity of tufts and a plurality of voids between the tufts, the tufts having fibers, the fibers having a diameter;

• wherein the improved unbonded loosefill insulation material has a higher insulative value than conventional unbonded loosefill insulation material at the same fiber diameter.
