Part 2/3:
The cooler middle is indicative of how insulation tends to retain a more stable temperature, effectively minimizing heat transfer compared to the surrounding warmer extremes. These extremes may correspond to areas where heat readily escapes or enters, potentially due to inefficiencies in the insulation.
Evidence of Insulation Inefficiency
Further analysis reveals a particular spot where the insulation appears to have "fizzled out," a clear sign of compromised structure or material fatigue. This area, characterized by a brief fizzing sound followed by cessation of insulation effectiveness, signifies a critical failure point where thermal insulation no longer performs as required.
