Europe's leading window brand

Internorm

We are a family company from Traun in Upper Austria with more than 80 years of tradition. Since the very beginning, we have been impressing our customers across Europe with the most modern windows and doors — "Made in Austria".

More than 1.900 employees and over 1.250 distribution partners in 21 countries guarantee a product quality with service expertise at the highest level. And not only with perfect quality, numerous innovations, excellent design, durable products and a highly developed manufacturing technology, but also with facts that speak for themselves. This is why we consider ourselves to be Europe's leading window brand.

No room, no house can do without them: windows and doors. And yet they are much more than just a matter of course. They fill a building with light, air and life.

At Internorm we develop and produce timber/aluminium, UPVC/aluminium and UPVC windows, as well as timber/aluminium and aluminium entrance doors to meet precisely this requirement: Open up rooms and buildings for living.

Product quality at Internorm

 

We practice a "total window and door system concept" — from research and development, in-house extrusion, the production of insulating glass, right through to the latest production technologies and logistics systems. Internorm therefore offers unique, industry-leading product quality.

Innovation at Internorm

 

Our expertise is based on more than 80 years of tradition but is nevertheless firmly focused on the future. Thus, in 1961, we were the first licence holders for the construction of UPVC windows in Austria. These days, Internorm is Europe's only window brand with multiple windows certified for installation in passive houses and is the market leader for high thermal insulation window and door systems.

With our innovative I-tec technologies, we have also been able to prove and consolidate our pioneering role in the development of forward-looking window systems.

To satisfy the high demands of product innovations, in recent years we have invested a total of EUR 180 million in research and development and in expanding our production plants.

Sustainability at Internorm

 

The high quality of our windows is expressed in their technical, functional, and design quality. Planned together with one of our architectural consultants, produced to a perfect fit and installed expertly by one of our distribution partners or our certified 1st window partners, they increase the value of the property.

As a responsible manufacturer of windows and doors, we know the relevance of our products for the energy requirements of a property — and the associated environmental aspects that must be considered. The thermal insulation properties of our products and technical equipment options are therefore particularly important to us.

And last but not least, we implement sustainable policies in-house too. Through continuous investments in environmental protection, ecologically improved production processes and more efficient manufacturing and distribution methods, we contribute to the preservation of valuable resources.
