What is another word for folding door?
Pronunciation: [fˈə͡ʊldɪŋ dˈɔː] (IPA) 
A Folding door, also known as bi-fold doors, are a popular choice for home interiors, patios, and balconies as they are space-saving and provide a modern look. However, there are alternative names for these doors, such as accordion doors, concertina doors, and folding patio doors. These names refer to the way the doors fold and retract to create an open, spacious feel. Additionally, retractable doors, sliding doors, and pocket doors are also popular synonyms for folding doors. The key difference between these synonyms is their mechanism and the direction in which they open; a sliding door slides to the side, a pocket door retracts into the wall, and a retractable door folds away like an accordion.
