Modern outdoor screen fabrics are designed to lessen the effects of the wind, let in light without blocking the view. Semi-translucent fabric allows you to see through lowered drop-down screens from the inside, but block out prying eyes from the outside.
Sidetracks are fitted onto the support legs/beams which encapsulate the edges of drop-down screens; this holds the screens firmly in place and also helps guide the screen for effortless opening and closure.
Optional wind sensors are available that detect potentially damaging winds and automatically roll the drop-down screens away. Like the louvre roof, the motorised operation of the drop-down screens is programmed into the one remote control.
