How does PU Foam Board perform in high humidity environments?

PU foam excels in humid conditions due to its closed-cell structure and low water vapor transmission. In tropical climates or high-humidity applications, it maintains thermal performance where other materials might degrade. However, proper vapor barrier installation is crucial to prevent interstitial condensation. The facing material selection becomes particularly important, with aluminum facers providing the best protection against moisture vapor drive in high-humidity conditions.
