Exterior sheathing panel with integrated air/water barrier membrane

In a method of attaching a membrane to a composite structure, a base portion of a fastener is affixed to a membrane such that a body portion of the fastener extends from a rear surface of the membrane. The body portion of the fastener is assembled with a retaining structure to secure the rear surface of the membrane against an exterior surface of the retaining structure. A curable composite is deposited against a front surface of the membrane, with the curable composite curing to form a composite structure attached to the front surface of the membrane. A detachment mechanism is operated to separate the body portion of the fastener from the base portion of the fastener, thereby detaching the membrane from the retaining structure.
