relatively minor, ranging between 0 to 3%. Additionally, when temperatures decline, the R-value of mineral wool ci increases substantially
due to a natural reduction in its thermal conductivity (due to reduction in radiation exchange within insulation materials). For example, as
the mean temperature drops from 75°F to 15°F, the R-value of mineral wool increases approximately 30% (from R-4.3 to R-5.5).
