Sunexx products: healthy light quality for people, the environment and the future
Light is more than just brightness; it is a biological stimulus and a natural source of energy that is crucial to our well-being.
Sunexx develops pioneering solutions for the controlled use of natural sunlight in indoor spaces. These solutions are scientifically proven, technically sophisticated and have been tried and tested in numerous applications.
In architecture, medicine, agriculture and leisure, Sunexx combines biologically effective light spectra with sustainable building physics and innovative material technologies.
With Sunexx products, you can enjoy the power of the sun everywhere, both indoors and outdoors, worry-free.
Scientifically proven mechanisms of action
Sunexx uses those specific wavelengths of sunlight that:
- ativate vitamin D synthesis, NO formation and other health-related processes
- have immunomodulatory, antiviral (including SARS-CoV-2 surrogates), antibacterial and antifungal effects
- promote serotonin release and regulate metabolic processes
- stimulate secondary plant substances/metabolites
- optimise growth processes in flora and fauna
At the same time, high-energy, cell-damaging UV-B, UV-A and IR components are selectively filtered out – with documented protective effects against:
- Sunburn, skin cancer, accelerated skin ageing
- Formation of free radicals
- Eye and cell damage
Studies at the University Hospital of Regensburg (2025) confirm the significant antiviral effect of filtered UVB light through Sunexx glazing.

Architectural & ecological added value
For healthy, natural light in rooms
Sunexx® is the pioneering glass that allows life-affirming, healing, soothing and germicidal sunlight into rooms, creating a new quality of living, working and growing environment.
Bring proven nature into rooms and achieve added value:
- daylight control & energy savings
- reduction in artificial lighting requirements & CO₂ emissions
- no active components – maintenance-free
- optimal indoor climate & protection with minimal energy consumption
Due to its material properties, normal float glass blocks the most important photobiological wavelengths of sunlight. Sunexx® breaks through this barrier, bringing nature into rooms.
Advantages of Sunexx glazing:
- $Formation of vitamin D and NO synthase
- $Formation of hormones- like serotonin
- $Stimulation & regulation of metabolic processes
- $Deactivates and reduces bacteria and viruses
- $Photobiological effect, valuable secondary metabolites
Antiviral effect: light as a biological protective measure
In times of increasing infection and potential future pandemics, Sunexx offers a decisive advantage.
Its selectively filtered sunlight (including UVB) has been proven to have the following effects:
- antiviral (*including SARS-CoV-2)
- anti-inflammatory
- cell-activating
(*In a study completed in 2025 at the University Hospital of Regensburg, the antiviral effect of UVB light filtered by Sunexx was investigated in depth. Using recognised SARS-CoV-2 surrogates in a practical test setup, researchers Prof. Dr. Mark Berneburg and Dr. York Kamenisch demonstrated that sunlight filtered by Sunexx has a significant antiviral effect in a bacteriophage model.)
‘We were able to prove that UVB radiation filtered through Sunexx glazing still has a significant antiviral effect.’
This makes Sunexx® the first known glass solution with a documented ability to naturally reduce harmful microorganisms. The virus and bacterial load in rooms can be reduced using only sunlight, with no energy consumption, chemicals or complex technology required.
Sunexx glazing is therefore an essential component of preventive health architecture in both residential and work environments. This makes it indispensable for public spaces, care facilities, and educational institutions.
In order to harness the healing power of the sun, it is essential to have reliable protection against harmful radiation
Sunexx has been proven to provide highly effective protection against the wavelengths of sunlight that are responsible for:
- $sunburn
- $accelerated skin ageing
- $skin cancer
- $allergic reactions
- $formation of free radicals
Conclusion: The oldest remedy known to humans, animals and plants, the sun can trigger and regulate many vital, performance-enhancing and health-preserving processes, particularly within the now harmless UV spectrum.
Conclusion: Health comes in glass format!
Sunexx® glazing opens up a new dimension in healthy architecture, where light becomes a preventive health measure, a natural hygiene factor, and a building block for a holistic, sustainable lifestyle.

Filter discs / panes
For healthy natural light in rooms
Radiation sources not only need to be covered and protected from external influences, light sources can also emit harmful radiation, especially in the UV range. In addition, the radiation doses of light sources change with the period of use.
Damage from undesirable radiation components can cause harm to humans as well as to plants. Therefore, harmful radiation must be selectively filtered out and the weighting of the rays must be adjusted.
Conservative UV radiation sources, as well as modern UV LEDs, are in most cases unable to radiate without harmful components, or to ensure that this occurs under certain – even unfortunate – combinations.
The filter discs – which are always matched to the radiation source – can independently filter out the harmful rays with high precision and improve the quality of the radiation source and the effects on humans, animals and plants.
For example, in irradiation equipment, quality improvements and therapy extensions in phototherapies) and in plants (e.g. vertical farming, horizontal farming, growth lamps, …) increase and prevent side effects or damage.
Filter films
Highly efficient and environmentally friendly sun protection.
The filter films are material innovations for the selective filtration and regulation of solar radiation with a unique filtration precision in nanometre accuracy.
The filter foils contain a complex layer structure which has proven itself worldwide and not only provides highly effective protection against the harmful rays of light (skin cancer, sunburn, allergic reactions, accelerated skin ageing, wrinkling, collagen degradation, formation of free radicals, …) but also specifically prevents heat and thus excessive sweating or high-water consumption.
The filter foils have a built-in intelligent wear index and you can see how the filtered harmful radiation would have irreparably damaged them, but without the protective effect diminishing. The filter foils are versatile and can be processed reliably.
Due to their high quality and purity, the filter films also form the basis for medical products. The filter films are available in roll form in widths of 1.20 m or 1.50 m.
