Batten elements are made of plastic or metal, such as galvanized steel, galvalume, or aluminum. Several alternate embodiments of battens are shown, along with a schematic illustration of a punch process for making the metal battens of the present invention. The batten elements all include holes or tunnels for the drainage of water through the batten elements. The alternate embodiments are shown in cross section or end view.

Ultrasonic welding apparatus is used for making roof flashing units. The roof flashing unites typically include a generally flat aluminum plate and a cylindrical aluminum element joined to the generally flat plate. Two ultrasonic welders are used to make the roof flashing unit, including a horizontally disposed ultrasonic welder for the cylindrical element and a horizontally disposed ultrasonic welder for joining the cylindrical unit to the generally flat plate.

Barometric damper apparatus is usable for both horizontal air flow and vertical air flow and thus comprises a universal barometric damper apparatus without a structural change. The barometric damper apparatus includes a plurality of louvers or damper blades pivotly secured to a frame and which pivot to the closed position under gravity when air stops flowing. Each louver includes a relatively short upstream portion and a relatively long downstream portion, with the relatively short upstream portion including a counterweight which causes the relatively short upstream portion to be heavier than the relatively long downstream portion so that the louver apparatus pivots to the closed position with the relatively short upstream portion always moving downwardly. A bend in the relatively long downstream portion allows the louver to contact the adjacent louver in the closed position so as to provide a seal to prevent air from leaking back through the damper apparatus.
