KF 520 - THE NEW WINDOW GENERATION

Internorm‘s new UPVC and UPVC/aluminium window KF 520 is the most attractive window in the range and additionally offers reliable security with the unique hardware I-tec Secure. The glass sash version on the outside of the window, the narrow view widths and the narrow frame resulting in more glass and therefore more light, comply with the high aesthetic demands of modern architecture.

There is no visible glazing bead inside, also no visible hardware – the impression of fixed glazing, but still an openable window.

The KF 520 facilitates larger glass areas due to 30% less view heights of frame and sash. Internorm is now also offering the premium glass coating ECLAZ® for the KF 520 as standard and thereby ensures up to 10% more daylight.

The unrivalled hardware I-tec Secure achieves security class up to RC3 in the KF 520. The KF 520 offers next to clear/puristic design also considerably more comfort in cleaning due to the smooth surface (no mushroom pegs as with conventional windows). The new hardware achieves additionally more smooth opening and closing.

The perfect solution for modern and contemporary architecture:

- Impression of fixed glazing, but still an openable window

- More glass due to window sash in glass appearance

- Less frame and more glass also on inside of window

- Puristic, elegant window design meets modern architecture
