Sliders have earned a reputation as the most versatile and economical door type for access to deck and patio areas. Vantage sliding doors now feature the flush-line sill for sleek good looks. This comes bundled with easy-glide sliding door panels that move effortlessly, an important benefit in these days of heavier double-glazed doors. Also available are multi sliders, which open to two-thirds of their width, and external sliding doors with a clean, minimalist sill section. View video.
