What do rope wicks in veneer walls typically replace?

Rope wicks in veneer walls are typically used in place of weep holes. This method allows for the management of moisture within the wall system. The wicks effectively draw moisture away from the wall cavity and allow it to evaporate, reducing the risk of water damage and mold growth. In contrast, weep holes serve a similar purpose but are more fixed openings that allow water to escape from the bottom of a wall. Rope wicks provide a more controlled and efficient method of moisture management, especially in certain designs where standard weep holes may not be as effective. This innovation reflects advancements in construction techniques, aimed at improving the durability and performance of veneer walls.
