UNBONDED LOOSEFILL INSULATION

摘要

An improved unbonded loosefill insulation material having a multiplicity of tufts (12) and a plurality of voids (14,16) between the tufts is provided. The tufts have an average major tuft dimension (MTD). The average major tuft dimension of the tufts of the improved unbonded loosefill insulation material is shorter than an average major tuft dimension of 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.
