Bi-fold doors are a type of door system that consists of multiple panels that fold back against themselves when opened. They are often used to create a seamless transition between indoor and outdoor spaces, making them popular for patios and gardens. When fully opened, bi-fold doors can provide a wide, unobstructed view and allow plenty of natural light into a room. These doors are typically made from materials like aluminum, wood, or uPVC, offering various styles to match different home designs. Bi-fold doors are not only functional but also enhance the aesthetic appeal of a space, making them a stylish choice for modern homes.
