Burglary protection for windows
The fundamental requirement to feel safe and secure in your own four walls is optimum protection from burglars as well as maximum security for children. Windows contribute to this considerably.
Therefore, all Internorm windows are equipped with standard security. I-tec glazing also contributes to burglary protection. The glass pane can no longer be pushed out due to the patented all around bonding of the pane with the window sash.
I-tec secure offers maximum protection and is installed in each KF 520 UPVC window. This locking technology is unique on the window market and absolutely unrivalled in the branch.
