Abstract
A vent for venting a building enclosure having a perimeter flange having a nailing means being made of a material with a low coefficient of thermal expansion, such as for example sheet aluminum. The vent further includes a grill structure and a cap. The cap is made from dent resistant plastic to facilitate mass production and low return rates. In a preferred form of the invention the grill structure is also plastic and is molded onto the low coefficient of thermal expansion nailing means. A method of molding the grill structure onto the nailing means is also shown.
