A punched window is set before the sill flashing membrane is lapped into the rough opening. The WRB is already cut around the opening. What should the crew do?
Correct Answer

Window flashing must be installed in water-shedding sequence with the WRB so water drains outward, especially at the sill. Other choices rely on sealant or omit critical parts of the flashing sequence.
