Our Serene Window Screens also come in privacy and blockout fabrics, so they can be used in lieu of curtains. Blockout Serene Screens are becoming increasingly popular for night shift workers as the side tracks mean that a room can be completely blacked out during the day. The housing protects the fabric when retracted up out of sight. Like all of our products, Serene Screens can be installed inside or outside. Our Double Legacy Screens suit a variety of door types, including Double French Doors and Double Sliding Doors as seen in these pics. They allow you to open up your home and let the fresh air in without compromising your view or letting flies and mosquitoes in!
