The upgraded sliding glass door system is engineered for the POWER+ gen 2 pergola to provide improved sealing, insulation and everyday usability in covered outdoor spaces. Panels use 10mm tempered glass to help control heat and cold while the enclosed sliding design protects against wind, rain and insects. A seamless gasket design improves privacy and weather sealing while a 100% aluminum rail system resists rust and corrosion for smooth, durable operation. The system is intended for year-round use on the Gen 2 pergola and is optimized for effortless daily sliding and improved comfort.
