Moisture barriers play a critical role in fireproofing systems by preventing moisture ingress that can adversely affect the integrity and performance of fireproofing materials. Fireproofing materials are designed to resist high temperatures and maintain structural stability during a fire. However, exposure to moisture can lead to deterioration, such as weakening the bond between the fireproofing material and the structural element, compromising its fire resistance capabilities.

By serving as a protective layer, moisture barriers ensure that the fireproofing maintains its structural integrity and effectiveness over time. They help to extend the lifespan of the fireproofing materials and maintain their protective qualities, which is essential in safeguarding the structural components of a building during a fire event.

While the other options may seem relevant in different contexts, they do not align with the primary function of moisture barriers in the context of fireproofing. Proper moisture management is crucial for fireproofing performance, making the prevention of moisture-related deterioration the key function of moisture barriers.
