    Abstract

    Transient tests of fiberglass insulation were examined theoretically to determine effects of radiation heat transfer. It was found that radiation dominates the heat flow process during the first several minutes, and that waiting times on the order of 20 to 30 min are necessary to achieve results consistent with steady-state tests. This time could be reduced if samples are oven-dried before testing.
