The folding door, known in our language as an "접이문" (Jeopimun), functions like an accordion, folding and unfolding to easily control lighting and ventilation as needed. Its curtain-like operation allows for convenient opening and closing.

Beyond serving as a window that connects and separates the interior and exterior, it plays a crucial role in blocking or allowing passage. In addition to its practical functions, it has become an essential item in interior design, adding a sophisticated and stylish atmosphere to otherwise dull spaces.
