Window Profile Style
KF 520
The new KF 520 combines innovative design with technical know-how. The window sash is not visible from outside due to its glass appearance and can optically not be distinguished from fixed glazing. This sash also contains the revolutionary locking I-tec Secure which renders levering of the window impossible – unrivalled in the branch. Integrated flaps press on all sides into the frame interior when locking and thus ensure maximum burglary protection.

Key Features
Energy Efficient Design
Our uPVC-Aluminum windows come with six internal chambers, engineered into two of the most insulating materials available. When supported by Internorm’s triple glazed units, U-values can be as low as just 0.62 W/(m²K). This is among the best that any window on the market can achieve.
Acoustic Insulation
Internorm uPVC-Aluminum windows are unique in that they are engineered with triple layer gaskets as standard. These three layers of perimeter sealing, alongside triple glazing and other innovations, contribute to outstanding levels of acoustic reduction in the home. Noise reduction offered can be as high as 47dB in this product range.
Secure, Concealed Locking
Only the most robust locking mechanisms are fitted to Internorm windows. Doing so ensures we are supplying our Distribution Partners with PAS 24 certified uPVC-Aluminum windows for their installations. These locks are discretely installed, concealed from eye to ensure sleek and modern sightlines.
