Insulation Behind Water Damage Walls Will Not Dry Out

Insulation is like a sponge and once it gets wet it will take a really long time to fully dry. The wet insulation will cause mold and foul odors even when the exterior wall has dried. Wall drying techniques are generally ineffective at drying insulation. Insulation abutting an exterior wall can absorb excess moisture and then transfer this moisture to the wall causing black mold.
