The BOLOGNA Hurricane Impact Thermal Break Aluminum Bi-fold Door by Rolansini combines thermal break aluminum framing with hurricane-rated impact glass for maximum energy efficiency and storm protection. This heavy-duty folding door system features low-maintenance finishes, multi-point security locks, and superior weather sealing. Ideal for residential and commercial applications requiring expansive openings, high wind-load resistance, and seamless indoor-outdoor transitions.

Product Advantages

One of the standout advantages of the BOLOGNA Folding doors is their ability to provide a full, unobstructed opening by folding to one side. This effectively solves the problem of reduced open space that is common with regular sliding doors. It is particularly ideal for balconies and courtyards, as it offers a large, clear view, bringing the outside scenery into the interior seamlessly.


In terms of safety design, the door's middle gap is specially crafted to prevent finger pinching. When closed, a rubber strip fills the space, ensuring the safety of users, especially children. Additionally, the upper rail features an anti-slip design, which guarantees that the door remains secure even in strong winds and heavy rain, significantly enhancing its safety and wind resistance.
