Final answer:
The minimum stagger between insulation and Protectoboard in roofing applications varies and is specified by the manufacturer, typically ranging from 6 inches to 2 feet to prevent water leakage or thermal bridging.
Step-by-step explanation:
The minimum stagger between insulation and Protectoboard installed in roofing applications typically refers to the intentional misalignment of their joints to avoid continuous seams, which can serve as paths for water leakage or thermal bridging. Usually, the manufacturer specifies the minimum stagger, and it commonly varies from 6 inches (15 cm) to 2 feet (61 cm), depending greatly on the particular system and application. It is crucial to refer to specific product documentation or standards for the exact requirements.
