As a result of a comparative test of moisture sustaining power, moisture-controlled building materials produced by other companies reached an equilibrium of no more moisture absorbance in two days. In contrast, COOL JAPAN continued absorbing moisture until about the 20th day, reaching to over 2.5 times of absorbance volume that of other hygroscopic building materials at equilibrium point.
Maximum absorption volume of COOL JAPAN boarder type (1㎡)
Test method: Measure the weight changes of test products after absorbing moisture to the limit of the product under the environment keeping constant humidity.
Suppression of dew condensation by COOL JAPAN border type
When the COOL JAPAN border type was put in a desiccator (moisture-proof box) to produce dew condensation artificially, the condensation almost disappeared after 3 hours, an effect of which continued even after 24 hours.
