A bi-fold is a type of door or window that consists of two panels that fold in half when opened. This design allows for a wide opening, making it ideal for connecting indoor and outdoor spaces. Bi-fold doors are commonly used in homes and commercial buildings to enhance natural light and provide easy access to patios or gardens. Bi-folds can be made from various materials, including wood, aluminum, and vinyl. They are often chosen for their aesthetic appeal and functionality. Many homeowners appreciate the seamless transition they create between rooms or between the inside and outside of a property, enhancing the overall living experience.
