A marine windshield frame for curved or straight windshield glass having a top frame rail mounted inward of the windshield glass and substantially flush with frontal surface of the windshield glass. The top frame rail is mounted onto the windshield glass edge by adhesive. The windshield frame may also include a pair of vertically oriented corner posts. The corner posts are preferably manufactured by die-cast molding. An alternate manufacturing method is to stretch-form an aluminum alloy extrusion, matching vent holes therein, and machined a taper thereon an edge.
