Abstract
A repulpable insulation material includes a batt formed of a mixture of thermoplastic binder fibers and cellulose fibers bound together by the thermoplastic binder fibers. The thermoplastic binder fibers make up about 0.5% to 25% by weight of the batt. The repulpable insulation material have a weight within a range from 1000 GSM to 1600 GSM. Subjecting the repulpable insulation material to a repulpability test produces greater than 85% fiber yield.
