I-Tec Innovations

Our internal research department is continually developing new products and technologies to be able to offer you even more comfort and security. Under the melodious title of “I-tec”, a range of revolutionary innovations, unrivalled on the market, has been created.


 I-TEC Core

With the new I-tec core we are processing thin glued timber layers in the core of the timber/aluminium window HF 410 which is only commonly known from highly stable roof beams and supports .

Your advantages:

  • Glued timber layers ensure very good load bearing and allow larger sizes
  • Considerably more humidity-resistant, more durable and extremely strong
  • Adapt the colours of your timber/aluminium window HF 410 to your living areas due to colour and timber variety
  • Narrow view widths for more light

I-TEC Locking

I-tec locking renders levering of windows impossible. This patent is unrivalled in the window brand and is already integrated in UPVC or UPVC/aluminium window KF 500. Integrated flaps press on to the inside of the frame from all sides when locking and therefore offer maximum burglary protection.

Your advantages:

  • Security class RC2 already as standard
  • Locking elements are almost completely integrated in the frame; this makes for easy cleaning
  • Low viewing height of UPVC and UPVC/aluminium window KF 500 ensures more light

I-TEC Ventilation

I-tec ventilation ensures comfortable and energy-efficient airing according to demands. The ventilation is already integrated in the window and can therefore easily be installed in refurbishments.

Your advantages:

  • Fresh air without great heat loss or draughts
  • Fresh air without dust or mould
  • Each room can be aired individually and according to demands
  • Ventilation is already integrated in the window – no need of opening windows for airing and increased security
  • Convenient operation via intelligent building control I-tec SmartWindow

I-TEC Shading

All Internorm window systems with integrated blinds can be equipped with I-tec shading. This sun protection without external power source works with photovoltaic module and batteries.

Your advantages:

  • Intelligent automatic mode facilitates automatic opening/closing of blinds through day/night recognition
  • Measuring solar irradiation and temperature reduces overheating of rooms
  • Several blinds, Venetian blinds or Duette blinds® can be controlled in combination
  • There are no energy costs
  • There is no extra installation or chiselling work required
  • The shading is situated directly between the panes

I-TEC SmartWindow

I-tec SmartWindow, the intelligent building control, enables you to easily and conveniently operate your ventilation and shading via Smartphone or tablet, no matter if you are at home or on the way.

Your advantages:

  • Convenient control via free App
  • Mobile control of I-tec ventilation, I-tec shading, sun protection and fan light opener
  • Opening control of your windows
  • Individual adjustments, exactly according to your requirements and options
  • Can be easily extended

I-TEC Glazing

Many window panes are only connected to the frame at a few points. As standard we are offering I-tec glazing, continuous all around fixing.

Your advantages:

  • Perfect stability
  • Optimum thermal insulation and sound reduction
  • Increased burglary protection
  • Efficient functioning of the window

I-TEC Insulation

I-tec insulation is inserted with pressure as granulate into the inside of the frames of UPVC/aluminium window KF 410 and KV 440.

Your advantages:

  • Gapless filling of chambers due to granulate
  • Increased thermal insulation
