VELUX CABRIO Windows System turns a roof window into an instant balcony in seconds and is a great way to add value to your home. The VELUX CABRIO balcony comes with safety glass as standard which combines a toughened outer pane and a laminated inner pane which means in the unlikely event that the glass does break it won’t shatter. It has a Clear and Clean coating on the pane too which will keep your window cleaner for longer. The upper Top-Hung Window opens outwards, can rotate 180 degrees and locks in place for easy cleaning of the outer pane. The bottom section unfolds into a glazed balcony with side railing. Can be used as an emergency exit. Comes with a VELUX 10 year guarantee.
