Internorm’s I-tec Secure renders levering of windows practically impossible. The specially designed lay-out of flaps instead of pegs which press towards the inside of the frame when locking, facilitates this and therefore works much better as security protection when compared with conventional locking systems.
Nowadays, an excellent standard of security in for windows and doors is essential, whatever the commercial project or application. We have integrated the innovative I-tec Secure already as standard in part of our commercial uPVC-aluminium product range.
There are several differentiated window security levels: in basic security, the window is locked with a peg. In class RC1N, windows are locked on all four corners. In the highest security class RC2N, which includes our I-tec Secure windows, security is ensured with all around locking flaps and these windows therefore are the best protected! As a result, as standard, Internorm windows and doors adhere to PAS 24 and Secured by Design regulations for UK security.
Our uPVC aluminium windows feature I-Tec Secure. Browse our range below for more information.
