Final answer:
The placement of end dams on window and door flashings depends on the specific building code relevant to the construction project.
It is not determined by a fixed height. Builders must consult the local building code or manufacturer's instructions to ensure proper installation.
Therefore, the correct answer is: option d). It depends on the specific building code.
Step-by-step explanation:
The correct placement of end dams on windows and door flashings is not determined by a fixed height, such as 6 feet, 8 feet, or 10 feet. Instead, the placement depends on the specific building code or manufacturer's instructions that are applicable to the construction project.
In general, end dams are important components designed to prevent water from penetrating the building at the lintels, sills, and jambs of openings.
The building code and best construction practices dictate their design and placement, and this can be influenced by factors such as the geographic location, the exposure of the building to weather elements, and the overall design requirements of the structure.
It is crucial for builders and contractors to reference the local building code and follow the guidelines set forth to ensure proper installation.
