The way that fiberglass insulation is designed in the laboratory does not reflect the way it is installed in today’s homes. Real-time studies provide evidence that the R-values of fiberglass insulation decrease significantly during winter conditions. Two research studies stand out in particular: Brock University’s Determination of Thermal and Moisture Behavior of the Structural Insulated Panel and the Oak Ridge National Laboratory’s Attic Testing at the Roof Research Center. Let’s take a look at the conclusions found in the following two studies.
