摘要:
A ventilating closure for an eave of a roof structure and a method for mounting a closure for an eave of a roof structure. The roof structure comprises an elongated support member positioned at and along the eave and plates or tiles positioned above the elongated support member and the elongated support member has an upper support surface facing the plates or tiles. The plates or tiles define an undulated lower side facing the upper support surface of the elongated support member. The ventilating closure comprises a mesh-type structure for allowing a flow of air to pass through it, and the mesh-type structure is a unitary structure which defines an elongated base portion for positioning along the elongated support member and for contacting its upper support surface. A first number of surface portions are positioned in sequence along the elongated base portion and protrude from said base portion for conforming to the undulated lower side.
