These upgraded Glass Doors are designed exclusively for the gen 2 POWER+ pergola to deliver refined privacy, weather protection, and year-round insulation. The enclosed sliding glass door system uses 10mm tempered glass and a seamless gasket design to improve sealing and reduce exposure to wind, rain, and insects. A 100% aluminum rail system resists rust and corrosion while the smooth sliding system enables effortless daily operation. The White 20' Side configuration integrates cleanly with existing Flexpatio pergola installations and provides improved comfort and privacy.
