Moisture Diffusivity of Cellulose Insulation

open access: yesJournal of Thermal Insulation and Building Envelopes, 1994
Test specimens of blown cellulose insulation were placed in contact with water to initiate an isothermal moisture intake process in which liquid water was allowed to enter freely against gravity into the specimens. The transient moisture distribution in the specimens was determined using the gamma-ray attenuation method over a period of 10 days.
