KF 520

KF 520


Internorm’s new UPVC and aluminium window KF 520 is the most attractive window in the range and offers reliable security with the unique hardware I-tec Secure. The glass sash design on the outside of the window, the narrow view widths and the narrow frame, resulting in a greater area of glass to capture more light due to 30% lower frame and sash elevations, meet the requirements of modern architecture. No visible glazing bead inside, also no visible hardware – the impression of fixed glazing, but still an openable window.

Statement of the jury

Thanks to the plain, slender construction of the frame system, the window optically emphasises the reduced stylistic language of modern architectural designs.
