The sunlight –
creative energy for life
Sunlight – The Natural Energy Source for Health, Life and Well-Being
Sunlight is the essential life force behind all living organisms on Earth.
It not only supports biodiversity, but also offers numerous health benefits for the human body and the natural environment.
The various wavelengths of sunlight – especially those in the UV range – trigger important photobiological processes that are vital to our health, well-being, and performance.
Key positive effects of natural sunlight include:
-
Production of Vitamin D
-
Activation of nitric oxide (NO) synthesis
-
Release of happiness hormones (e.g. serotonin)
-
Strengthening of the immune system
-
Natural inactivation of viruses and bacteria
-
Stimulation of skin pigmentation (tanning)
However, the human body is highly sensitive to both overexposure and underexposure to certain UV wavelengths.
A deficiency can lead to a lack of Vitamin D, while overexposure may cause sunburn, skin cancer, or premature skin aging.
Conclusion:
Sunlight is an indispensable natural regulator for the body, mind, and nature – but only when used in the right balance.
Targeted filtering and control of solar wavelengths open up new possibilities for:
-
Health-supporting architecture,
-
Biological glazing solutions, and
-
Sustainable interior concepts that harmonize with nature.
The Sun – Elixir of life for indoor generation
We now spend up to 90% of our time indoors – often under artificial lighting and without exposure to the essential photobiological components of natural sunlight.
This has consequences:
Our bodies, health, and overall well-being suffer when we lack the vital wavelengths of sunlight – especially UVB and short-wave visible light.
Even plants and animals kept indoors are deprived of the natural light they need to truly thrive.

Sunexx brings the power of the sun back inside.
Our innovative glazing technology selectively transmits the health-promoting wavelengths of sunlight – enabling greater quality of life, vitality, and natural balance in modern indoor environments.

Skin cancer
-
Premature skin aging
-
Free radical formation
-
Cell damage (e.g., mitochondrial DNA)
-
Light allergies and inflammation of skin and eyes
These harmful rays are effectively filtered out, protecting skin, eyes, and hair – without sacrificing the natural feel and benefits of sunlight.

Sunexx – The Smart Shade Provider
In the Sunexx shade, you can enjoy the healing warmth of the sun – risk-free and full of benefits.
An optional heat-reflection layer enhances comfort with a cooling shade effect – perfect for hot summer days.
Sunexx – The Evolution of Filter Innovation in Glass
Sunexx is the advanced evolution of the proven glass-based filtration technology originally developed by Klaus Lang.
With Sunexx, pure, natural sunlight enters your living, working, or recreational spaces in a safe and controlled way – promoting health, well-being, and growth.
