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.

Manufacturing expertise and at the same time supplier independence was further extended with the erection of a plant to produce toughened security glass (ESG) on the Traun site.
The specially thermally insulating glass is characterised by increased impact strength and is resistant to large temperature differences.

I-tec ventilation and I-tec shading can be controlled via the intelligent home control. Controls for sun protection and fanlight opener as well as opening control are added later. Mobile control when you are on the way are possible through this, too.

Internorm develops the first three revolutionary I-tec innovations:

• I-tec secure: unrivalled, fully integrated locking

• I-tec shading: first photovoltaic blind in the window with integrated blinds

Founding of the international window network. Next to Internorm, independent, specialised companies develop with the aim to use knowledge transfer and innovations of common synergies.

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.

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

The 2. 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.

Direct distribution stops: Internorm products are exclusively available via qualified specialist traders - this is unique in the brand.

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

A UPVC window production plant is built at the Lannach site in Styria. In 1988 the first Internorm timber window are produced in this plant, nowadays the plant specialises in timber/aluminium products.

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

Internorm acquires a local window factory in Sarleinsbach/Upper Austria and converts this into a UPVC Competence Centre.  In 1979, in-house extrusion starts.

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

In Traun in Upper Austria, a UPVC window factory is being built. This is also the birth of the Internorm brand. Internorm's first brand appearance occurs at the exhibition stand of E. KLINGER.
