The innovative SR6700 aluminum window system is designed to replicate the original steel windows used in many historic and commercial buildings. With its true “floating vent”, large sizes and minimal sightlines, the SR6700’s one-of-a-kind design has been approved for use on several National Park Service registered landmark projects.
