In 2001, the company founder Klaus Lang, came up with the idea to develop a sun filter system in order to extract only the best qualities out of the sun. In 2004, the first so called „Helio-protec“filter films, were produced, and were now ready to be examined by the medical in-vivo and in-vitro-tests.

From 2005, after successful completion of above tests, the filter technology was renamed “HelioVital”, Some applications were developed and sold to customers, for example the „HelioTent”, a combination of beach mat and healthy shade provider. Between 2006 to 2010 the company was awarded a lot of industrial awards. Since 2010, more and more successful applications have been made available to the market. 

The latest studies in human and biological research have shown unique effects in the protective effect, but also in the health and growth-promoting effects of filtered sunlight and have driven the further development of special glass as a basis and the integration of the filter technology in glass. After extensive research and many years of testing, this innovation has been successfully implemented in glass ready for series production, which from now on will enable decisive biological light advantages in rooms as glazing material for buildings and greenhouses. In order to meet the increasing market demands worldwide, Sunexx GmbH was founded.

Sunexx is the completion of the proven HelioVital filter innovation in glass and reliably brings pure natural sun into rooms for healthy living and working spaces.
