A glass balustrade was selected for the straight flight to allow light to flow freely into the living area and to create an uncluttered space (defined by the clean lines of the grooved top hand rail and wide bottom stringer). The invisible barrier works beautifully with the 2" squared-off oak treads, matching oak risers and strong-routed poplar stringers; it definitively improves the modern feel of the home.
