Westlake Royal Building Products has expanded its Magnolia Collection with a new black frame option, bringing a bold, contemporary look to its classically inspired vinyl windows. Available across the 400/4000 Series and 450 Series in single hung, slider, and picture window styles, the black finish is featured on both the interior and exterior for a cohesive look. The windows also are engineered for lasting performance by combining multi-chambered vinyl construction, all-welded frames, aluminum sash reinforcement, and energy-efficient insulating glass.
