Internorm I-tec Insulation: A Game-changer in Window Technology

In the industry of windows and doors, innovation plays a vital role in delivering superior performance. Internorm, a leading name in this field, has once again set new standards with its I-tec Insulation system. This ground-breaking technology offers a host of benefits, from enhanced thermal insulation to environmental sustainability, redefining the way we view window technology.

Unveiling the I-tec Insulation Innovation

Internorm’s I-tec Insulation is a pioneering solution that ensures optimal thermal insulation for your home. Unlike traditional methods that use foam to fill the cavities of windows, I-tec Insulation employs granulate. This innovative approach results in significantly lower U-value, implying excellent thermal insulation properties1.

The Green Approach: HCFC-, HFC-, and FC-free Insulation Materials

Internorm is not just committed to providing high-quality products but also to minimizing environmental damage. The I-tec Insulation uses insulation materials that are free from HCFCs (Hydrochlorofluorocarbons), HFCs (Hydrofluorocarbons), and FCs (Fluorocarbons). These substances are known to contribute to global warming and ozone layer depletion2. By choosing environmentally friendly materials, Internorm is taking a significant step towards sustainable practices.

Lower Heating Costs and Improved Thermal Insulation

By achieving a lower U-value, windows with I-tec Insulation offer excellent thermal insulation3. This means less heat escapes from your home during the colder months, reducing your heating costs. Conversely, during the warmer months, the insulation helps keep your home cool by reducing the amount of heat entering from outside.


The continual filling of cavities with granulate ensures there are no gaps in the insulation4. This improves the overall insulation performance, offering you a more comfortable and energy-efficient home.


The Internorm I-tec Insulation system represents a significant leap forward in window technology. It combines enhanced thermal insulation with a commitment to environmental sustainability. With I-tec Insulation, homeowners can enjoy the comfort of a well-insulated home while also contributing to the preservation of our environment. This unique blend of innovation and responsibility is what sets Internorm apart in the industry.
