Where is the base flashing installed when using brick veneer for the outside finish over wood frame walls?

The correct answer regarding the installation location of base flashing in a brick veneer application over wood frame walls is indeed between the sheathing paper and the wood sheathing. This specific location is critical for ensuring that any water that penetrates the veneer or the exterior wall system is properly redirected to the exterior, preventing moisture from causing damage to the structural components of the wall.

Installing the flashing in this position creates a barrier that directs water away from the wall assembly. By placing it between the sheathing paper and the wood sheathing, it ensures that any moisture that breaches the brick veneer does not compromise the integrity of the wood framing or insulation, effectively protecting the building's structure from potential rot or mold growth.

This installation technique is essential in maintaining the longevity and performance of the wall assembly in a brick veneer application, emphasizing the importance of proper moisture management in construction practices.
