A Comparison of Korean Cellulose Insulation with Cellulose Insulation Manufactured in the United States of America

Abstract

Thermal resistivity data are reported for loose-fill cellulose manufactured in Korea and the United States over the temperature range 40 to 100 F. A representative thickness of 1.1 in. for thermal test specimens was determined for cellulose insulation in the density range that was studied. Measurements for insulations with known amounts of fire retardant chemical showed a negligible effect of the fire retardant on the thermal resistivity of the insulation. The test data show that the U.S.-made loose-fill cellulose that was studied had a 5% greater thermal resistivity than the Korean-made product. This difference in thermal resistivity could be due to differences in the re-cycled paper being used in the two countries to produce cellulose insulation
