The Breakers Resort Retractable Glass Wall, manufactured & designed by Roll-A-Cover, opens the restaurants indoor patio to the outdoors in moments by simply retractable the walls. So, instead of a conventional fixed room with fixed walls, a retractable glass wall gives the indoor space an outdoor ambiance even when the wall is closed. Unlike a bi-fold door, the bays of this sliding glass wall retracts into one another so there is no loss of space inside.
