If you are living in a penthouse apartment, you might feel distressed because you would not have enough outdoor space. On the other hand, by virtue of the roof window system, you can still have the chance to turn any room in your apartment into a room full of sunlight and fresh air.
When you replace your old window with this window system, you will also have a small terrace or balcony where you use it. With this practical window system, you can turn your roof window into a balcony in less than 5 seconds. For this easy change, the only thing you have to do is to open the window as you see in the gif below.
