A vent (100) suitable for a tiled roof and including a vent member (102, 234, 242, 254) and a sealing member (104), the sealing member including a pleated, malleable material. The sealing member conforms to the uneven surface of the roof and seals the vent and roof from ingress of precipitation, particulates, and insects, while allowing the building to be ventilated.
A heat exchanger core is fabricated, from plastic sheets with a flat side and a corrugated side. The plastic sheets are stacked so that the corrugated sheets define two flow paths. The plastic sheets are held in a stacked position by a retaining member.

An air vent for tiled roofs (50) is installed for air exchange occurs through a slit (64) near the roof apex (62). The vent has a plurality of layers of corrugated materials defining a plurality of airways for air exchange. In one embodiment, a baffle is attached to a vent member. In another embodiment, a plurality of vent members (104) is attached to a top panel, which may be made from the corrugated material, optionally with a route exposing airways for additional air exchange. A membrane may be present on the embodiments to prevent ingress of water, particulates, and insects into the roof interior. A covering member and/or a layer of cementous material may be used to further prevent undesired ingress of water, particulates, or insects. If present, the covering member is adhered to a lower panel of one embodiment and disposed below the baffle in another embodiment.
