RB Tehnika Ltd. was established in 1999. Initially, the primary business activity was the production of aluminium windows and doors. In addition to manufacturing, company started with the development of software for construction and development of aluminium and PVC windows and doors. The project was called STIJENE (eng. 'Walls'), because of the terminology "aluminium (or PVC) wall", which is often found in the descriptions of windows and doors. 

The development of the first version of the program was completed in early 2001, and at the end of 2001, with the beginning of license sale, the segment for the production of aluminium windows and doors was shut down, and the company continues to develop software exclusively.

Program STIJENE is currently actively used by more than 1100 manufacturers of PVC, aluminium and wooden windows and doors, mainly from Croatia, BiH, Slovenia, fewer from Kosovo and Macedonia, and individually from Western Europe. The software has been translated into Slovenian, Albanian, Macedonian, German and English language.

 

We successfully cooperate with producers and distributors of PVC and aluminium profiles, fittings, accessories, and machines in order to provide better support for our customers. 

We currently employ 19 people of different educational backgrounds of most technical areas: computer science, mathematics, engineering, mechanical engineering and electronics, and thus cover the various technical aspects required for the development of specialized CAD / CAM software.
