2021

90 Years Anniversary

From the one man company to the largest international window brand in Europe! This long and successful development and Internorm's tradition and innovation makes the third generation - Anette Klinger, Christian Klinger and Stephan Kubinger really proud of.

2020

I-tec Secure

The non-comparable locking mechanism I-tec Secure is standard in the UPVC or UPVC/aluminium window KF520 . Security class RC2N is standard (with lockable handle) - up to RC3 upon request.

2016

I-tec Core

Another I-tec innovation is put on the market: Glued timber layers ensure more stability and strength in the window core. This timber is considerably more humidity-resistant, more resilient and extremely strong.

2015

500,000 Entrance doors

In 1998, Internorm put the first aluminium entrance door with foam insulation core on the market. Next to four aluminium door systems, Internorm also offers two timber/aluminium door systems today. Our customers value the high-quality processing and individual design possibilities. In 2015 therefore, the 500,000th entrance door was produced.

2012

I-tec Innovations

Internorm develops the first three revolutionary I-tec innovations:

I-tec secure: unrivalled, fully integrated locking
I-tec ventilation: ventilation system integrated into the window frame
I-tec shading: first photovoltaic blind in the window with integrated blinds

2002

Introduction of FIX-O-ROUND Technology

For the first time glass panes are glued to the sash at Internorm. This considerably improves stability, thermal insulation, sound reduction, burglary protection and functioning of the window for its entire lifetime.

2001

Start of Timber/Aluminium window production

Internorm develops a completely new type of timber/aluminium window system and meets customers' demands for maintenance-free "timber windows".

Third generation

The second generation withdraws from the operative business to the supervisory board of directors and delegates one of their children respectively – Anette Klinger, Christian Klinger and Stephan Kubinger – to the management board.

1986

Windows with integrated blinds

Internorm develops the window with integrated blinds, a window with integrated sun and privacy protection between the panes.

1983

Export campaign

Internorm is starting to export to Germany, Italy and Switzerland. In Turkey, shares in the company Campen A. S., Bursa are acquired.

1979

Internorm3

The revolutionary system "Internorm3“ - 3 panes and 3 gaskets - is introduced to the market with great success.

Second generation

Eduard Klinger sen. involves his three children Eleonore, Eduard and Helmut in the company with 25% stakes each.

Factory Traun / The Internorm brand
