With Balco’s unique Twin window, you get two systems in one, including maximum flexibility and the ability to open the whole balcony. This elegantly designed glass window can be opened as a standard sliding window and folded in like a folding window.
The Twin window is also easy to operate; all it takes is a light grip on the frame to slide the window to the side. When you want to fold it in, you simply lower the discreet handle in the window frame to fold each individual pane until you have a completely open balcony. Convenient when you want to clean the exterior of the glass panes.
