Thermal insulation helps reduce exterior temperatures affect the interior temperature. In tests it showed a difference between 10C-20C the thermal insulation prevents heat/cold from transferring inside and outside the unit. It is placed on the aluminium panels of the roof and doors. The thermal insulation is a must if you choose to go for dark panels as they tend to attract more heat than the lighter panels. It is great for people that intend to put 2nd battery systems or chargers in the rear of the load box as it allows the systems to run more efficiently or those who run a camping fridge allowing cooler air pulled through the compressor.
