"미닫이" refers to a traditional Korean sliding door, commonly used in homes and buildings. These doors are typically made of wood and feature a simple yet elegant design, often adorned with decorative paper or glass. They slide open and closed, allowing for efficient use of space in smaller rooms. The design of 미닫이 is not only practical but also reflects the aesthetic values of Korean architecture. They are often found in conjunction with other elements of traditional Korean interiors, such as 온돌 (ondol) heating systems and 한옥 (hanok) structures, creating a harmonious living environment.
