Right – two-thirds of the blue butyl flashing tape is above the sheathing seam; the top edge of the butyl flashing tape is covered with clear sheathing tape that is also offset so two-thirds is above the top edge of the butyl flashing.
Image
Right: All joints in the rigid foam are taped to keep stucco out of joints for even drying. Mesh tape (shown here) is used with expanded polystyrene (EPS); acrylic sheathing tape or self-adhered membrane is used with XPS
