Revolutionary Technologies at Internorm

In order to meet the rising demands on design, technology, quality and comfort, Internorm has developed a series of revolutionary technologies – I-tec.

I-tec Ventilation

  • A ventilator is completely integrated into the frame so even when your windows are closed; fresh air can circulate 24/7

I-tec Locking

  • Maximum burglar protection
  • Invisible locking and closing elements make cleaning windows easier than ever

I-tec Shading

  • Integrated blinds for sun and privacy protection
  • Day/night recognition allows for automatic opening and closing of the blinds at sunrise and sunset

I-tec Glazing

  • Unlike most other window panes that are connected to the frame in only a few positions, Internorm uses FIX-O-ROUND technology meaning there is a continuous connection of the glass pane to the frame, improving stability, thermal performance and sound insulation.

I-tec SmartWindow

  • Home or away, adjust your blinds and much more using the free smartphone app
