I-Tec Core Logo Latest

I-Tec Features
Include:

  • Individual combination of colours and timber types
  • Use environmentally friendly and sustainable materials
  • Suitable for larger commercial window solutions
  • Fantastic durability
  • Extensively reliable

The I-tec Core consists of thin, laminated timber layers located inside a range of our Internorm timber-aluminium windows. Highly weather resistant aluminium is attached to the outside of the window which protects the core and the timber. The colour as well as the timber type can be adapted to the requirements of your commercial project and for any application with our timber-aluminium solutions. Our woodgrains include oak, ash, walnut, larch and spruce, for the inside of the window.

I-tec Core renders these windows (or doors) especially tough and reliable, which facilitates the option for larger window solutions. Furthermore, in contrast to other timber windows, I-tec Core technology is particularly humidity resistant. A further special feature of this innovation is that only timber of sustainable forestry with PEFC quality seal is processed. This means we can guarantee you sustainable products with resource-saving manufacturing and flawless design.

Change from technology to sentiment

Bring the outside into your home! Our commercial timber-aluminium solutions combine technology and excellence with innovative technology, highest stability, extensive colour choices. The video shows its history, starting from the product idea to sales in the showroom of our Internorm distribution partners.
