Folding Doors
A Book-Like Opening

Redefine Your Space
The sashes overlap and pack one on top of the other to create the widest possible opening without interruptions. Thus obtaining a large window that completely opens the house to the outside.
​A system that allows you to make the most of and merge the environments together. Creating a unique space without any element that interrupts the continuity.
Glass surfaces for large openings
The window sashes close on themselves, reducing the space they occupy in the room to a minimum. The book-style sliding allows for multiple sashes that overlap, sliding smoothly on the lower frame.
