Final Answer:
When installing a cap sheet corner detail, it should wrap around the inside corner in the opposite direction as the base sheet.
Step-by-step explanation:
The proper installation of a cap sheet corner detail involves a strategic consideration of water shedding and seam integrity. In roofing systems, cap sheets are used as protective layers to prevent water infiltration. When wrapping around an inside corner, it is essential to ensure that the cap sheet is positioned in the opposite direction as the base sheet. This is because the opposing orientation facilitates a seamless overlap, directing water away from the vulnerable corner joint.
By wrapping the cap sheet in the opposite direction, any potential water runoff is effectively channeled away from the corner, reducing the risk of leaks and enhancing the overall waterproofing performance. This technique creates a more robust and resilient seal, safeguarding the building structure against moisture damage. Adhering to this installation practice aligns with best practices in roofing, where meticulous attention to detail is paramount for long-term durability and weather resistance.
