Thermal bridging occurs when heat transfers through conductive materials like metal van walls. Closed-cell spray foam provides the highest R-value per inch (R-6 to R-7) and acts as a vapor barrier, preventing condensation. Thinsulate offers good insulation without taking up space and provides excellent sound deadening. Havelock wool is natural, breathable, and handles moisture well but requires careful installation to prevent settling over time.
