Bi-fold windows
Bi-fold windows consist of multiple panels that fold in on each other, creating a wide opening. They are often used in commercial buildings, restaurants, and homes with large outdoor areas.
Aluminium bi-fold windows are popular because they provide a large opening, allowing for plenty of natural light and ventilation. They are also energy-efficient and offer good insulation.
