History and developments to date

Guillaume Janssen was established in 1967 as a trading company for components of sun protection systems. In the 1980s and 1990s, it evolved into a full-fledged manufacturer of sun protection systems. In the 2000s, after a reorientation, the focus shifted to the fabrication of sun protection fabrics. In the 2010s, unique sun protection systems were added to our portfolio. From this decade onward, the focus has been on the international expansion of manufacturing distinctive sun protection systems and fabricating sun protection fabrics for various applications.
