This sliding glass panel can be used as a substructure system for practically any type of roofing. Thanks to its free-standing design, there are no extra costs for the structural adaptation of the patio roof or pergola awning when retrofitting. Not only suitable for patios and balconies, the w17 easy can also be used for indoor spaces. Every w17 easy is equipped with the new Soft-Closing System, which enables the glass elements to be moved quietly and effortlessly.
