A sliding door is commonly used nowadays and it refers to a door that can be opened by sliding the door leaves back and forth. Sliding doors usually consist of two door leaves and they are fitted to runners which allow smooth operation.
Unlike traditional swing doors, sliding doors don’t take up much space for the door to swing open but compared to bi-fold doors, sliding doors have a smaller entrance way as only one of the door leaves moves. When opened, the moving door leaf will slide in front of the stationary leaf, resulting in half the entrance way being blocked.
However, sliding doors are still functional for space maximization. With the development of technology and the diversification of decoration methods, the materials of sliding doors range from traditional wooden materials, to glass and aluminium materials. In architectural design, sliding doors are commonly being used as bathroom door or kitchen door.
Besides, sliding doors are also frequently used as exterior doors such as villa doors, patio doors, living room doors, balcony doors, store doors, studio doors, garage doors and so on.
