Glazing systems for your home with resilient profiles, thermally-efficient glazing, excellent insulation, reliable security, superb shading, smart operation and outstanding ventilation.
I-tec Secure from Internorm is designed to resist modern burglary methods such as levering, helping reduce the risk of break-ins. Instead of conventional locking pegs, the system uses integrated flaps that securely lock the sash while keeping the entire mechanism concealed within the frame.
With fewer components, I-tec Secure hardware is also easy to clean and maintain. Because the locking elements are integrated into the sash and do not protrude like traditional systems, they remain discreet and simple to keep in good condition.
Window security systems are rated across different protection levels. Basic systems rely on peg locks, while windows that lock at all four corners can achieve the RC1N security class. I-tec Secure meets the higher RC2N classification, securing the sash continuously around the entire frame for enhanced protection.
As standard, all Internorm windows and doors meet the requirements ofPAS 24 and the police-backed Secured by Design scheme, giving homeowners confidence in long-term security and performance.
With advanced multi-layer glazing options and innovative frame technology, these windows help reduce heating demand, improve indoor comfort, and support sustainable building practices. Ideal for new builds and deep retrofits, Internorm’s Passivhaus-certified range provides reliable, high-performance solutions that contribute to a healthier and more efficient living environment.
