These Aluminium Folding Windows use the same tried and trusted system that we use for our excellent continental Folding Doors. With widths up to 6 metres, when open they can leave around a 90% clear opening. There are lots of opening styles such as all panels folding one way, some folding one way and the rest sliding the other.
