What is the function of house wraps?

• A. Stop air infiltration
• B. Stop passage of vapor
• C. Allow water vapor to pass through
• D. Allow liquid water to pass through

Answer: (C)

House wraps play a crucial role in building envelopes, primarily designed to enhance the performance and durability of a structure. The primary function of house wraps is to allow water vapor to pass through while preventing liquid water and air infiltration. This characteristic is essential in managing moisture within the wall assembly, which helps to prevent mold growth and structural damage that can arise from trapped moisture. House wraps are typically made from breathable materials that can effectively manage moisture and help to maintain a balanced indoor environment. By allowing water vapor to escape while keeping water and air from entering, house wraps contribute to the overall energy efficiency and comfort of the home. This is why the function of allowing water vapor to pass through is a key aspect of their effectiveness in building construction.
