KF 520 UPVC-ALUMINUM WINDOW

The Internorm KF520 model is truly a window like no other. This award-winning window has earned both the German Design and German Innovation awards in 2021 and 2020, respectively. What makes this particular model so special is its sashless profile. With this innovative feature, it's impossible to distinguish between operable and fixed windows from the outside, which creates a beautifully uniform appearance for any new build. With slim and modern profile, this model is both innovative and elegant.

The Internorm KF520 model is a game-changer in home security, thanks to its unrivalled I-tec systems that offer superior safety measures as standard. The I-tec Secure locking mechanism is a standout feature that is virtually impossible to lever out, and it's available up to security class RC3. With hidden locking parts, the window frame has an aesthetic appearance that complements any home's design, which makes it easy to clean and maintain. The I-tec glazing technology ensures maximum security with all-round bonding of the insulating pane, providing a perfect seal against any attempts to break in. With slim frame and a higher proportion of glass, there's also more natural daylight, making your home brighter and more inviting. The premium ECLAZ® glass coating as standard provides added durability and long-lasting UV protection.
