1. Multiple Panels: Bifold doors consist of two or more door panels that are hinged together. These panels can vary in number, but common configurations include two, three, or four panels.
2. Folding Design: When opened, the panels of a bifold door fold and stack neatly to one side, creating a wide opening. This folding action allows for maximum flexibility in terms of how much of the doorway can be opened or closed.
3. Tracks and Rollers: Bifold doors are equipped with top and bottom tracks and rollers that facilitate smooth and easy operation. The rollers allow the panels to slide along the tracks when opening and closing.
4. Glass Panels: Bifold doors often feature large glass panels that provide unobstructed views of the outdoor space. These glass panels can be single-glazed or double-glazed for insulation and to make the room they're in more energy efficient.
5. Materials: Bifold doors can be constructed from various materials, including aluminium, timber, uPVC (unplasticised polyvinyl chloride), and composite materials. The choice of material can impact the door's appearance, durability, and maintenance requirements.
6. Security Features: Many bifold doors come with multi-point locking systems and other security features to ensure the safety of the property.
7. Indoor and Outdoor Use: Bifold doors are commonly used to create expansive openings in exterior walls, leading to patios, decks, gardens, or other outdoor areas. They can also be used as interior doors to divide spaces within a home, such as between a living room and a dining room.
8. Customisable: Bifold doors can be customised in terms of size, colour, and design to match the aesthetic and functional requirements of a particular space.
