⸻ uPVC Windows

KF 520

The KF 520 seamlessly blends innovative design with advanced technology. Its window sash is concealed from the outside, creating a sleek, glass-like appearance that is indistinguishable from fixed glazing. This sash features the ground-breaking I-tec Secure locking system, which prevents the window from being forced open – a feature unmatched in the industry. Integrated flaps press firmly into the frame when locked, providing exceptional security and maximum protection against break-ins.
