R-Value Myth

To the average person the higher the R-value of your insulation, the warmer you should feel in the winter and cooler in the summer. The reality is something totally different because the R-value listed on insulation is not determined under real world conditions making them extremely misleading to the consumer. They do not account for air infiltration and exfiltration, air intrusion, solar heat or conduction.
