BI-FOLD WINDOW

A bi-fold window consists of multiple panels hinged together that fold back accordion-style, creating a wide opening that connects indoor and outdoor spaces. This design is popular for kitchens, patios, and living areas where you want to blend interior living with gardens, decks, or balconies. When fully opened, bi-fold windows can remove up to 90% of the barrier, maximizing ventilation and natural light. They offer flexible configuration—fold all panels to one side or split them in the center. Modern bi-fold windows use thermal-break frames, double or triple glazing, and multi-point locking for energy efficiency and security. The downside is they require clear space for panels to stack and can be costlier than standard styles.
