Exposure to direct sunlight can cause many coloured or painted materials to fade. Ordinary glass allows harmful UV light to pass through, thus fading goods.

Fade reduction film, applied to the inside of ordinary windows, can filter out up to 99.5% of the damaging UV light, whilst still allowing visible light in.
Films can also be chosen to reduce fading due to visible light, and infrared radiation from the sun.

UV Protection

There is no complete protection from fading materials, since diverse factors are responsible for fading. However, it is possible to retard with clear UV protection film, and further preventive measures against fading.
Factors which lead to fading:

• The main factor for fading is the UV light.
• A further factor is the visible light.
• The long-wave Infrared light also represents a factor. IR light can be reduced only by metallized films.
• The artificial lighting of rooms is important as well. In principle, everybody should be warned of halogen emitters, which are not UV arm. These can deliver, without disk, UV-A and UV-B light, with disk UV-A light.
• Further factors for fading can arise as a result of humidity, environmental impacts and warmth.
• The last important factor for fading, is the art to see the ware. Not only the colours are responsible for the fading effect, but also the material used (Quality standards for colour stability).
