Feel the openess


The steel window systems from RP Technik open up new architectural possibilities, whether in new buildings or in renovation projects subject to monument preservation requirement. They allow you to plan with extremely slim steel window frames widths from 45 mm and elegantly linear profile designs which can be executed in the same look as our steel door and partition wall systems, thus creating a uniform overall appearance.
