Beautiful views are best enjoyed standing upright.

There is minimal obtrusive sash protruding into your living space, blocking the view or creating an obstacle course on your way to the open window. True to the Roto principle: “More freedom. More comfort.“ Use all the top-third pivot roof window‘s functions easily with one handle – positioned at the bottom for better accessibility.
