Causes of Fading
The sunlight is one of the causes of fading that happens over time. A question that many people ask is, “Can I prevent it?” Fading is inevitable and the same applies whether it is caused by exposure to intensive sunlight for a short time or a long exposure to the weaker light of cloudy overcast days. Here in the North East, the sun’s damage can be especially harmful, because, in spite of our cloudy winter months, damage from fading still continues.
Visible light and infra-red heat are other factors that contribute to fading, which is why effective film installations must harness all three sunlight elements. Ultraviolet light rays bounce off solid objects-buildings, trees, streets, etc. Therefore regardless of a window’s compass orientation, you can still have a fading problem. Natural fibers like silk or wool are less fade resistant than synthetic fibers. Antiques, tapestries, rugs, etc.,
Elements of Sunlight
To understand the causes of fading, one needs to know a little about the makeup of sunlight. Sunlight is basically made up of three elements:
- Visible light – the part which enables us to see
- Infrared light – the part which we feel as heat
- Ultraviolet light – we cannot feel it or see it, but it is the main factor in causing fabrics, furniture,
andworks of art to fade.
Fading is a result of these three “sunlight “ factors and, to a lesser degree… indoor artificial lighting, humidity
Will 3M™ Sun Control Window Film stop my furnishings from fading?
Nothing stops fading. 3M™ Sun Control Window Films help reduce the major causes of fading (ultraviolet light, visible light, and solar heat), thus helping to prolong the life and preserving the appearance of your furnishings. As a general rule of thumb, Ultraviolet (UV) is approximately 40% of the cause of furniture fading, visible light about 25%, and heat about 25%. The remaining 10% can be attributed to humidity, pollutants, interior lights, dye anchorage, and other causes.
Summary Facts About Fading
FADING IS INEVITABLE… all materials fade in time.
FADING OCCURS… whether exposure is from intense sunlight over a short period of time or weak sunlight over a long period of time.
SEVERE FADING CAN BE MINIMIZED… with the use of 3M™ Solar Control Window Films.
Reducing the Inevitability of Fading
- Average clear glass filters 25%
- Dual-pane glass filters 50%
- Low-E glass filters 60%
Our 3M™ Sun Control Window Films filters 99.9% of UV Window film is an effective means by which to help reduce fading. Remember, you can never fully eliminate fading.
Laboratory tests using Xenon arc simulated sunlight per test conditions from The American Association of Textile Chemists and Colorists show that furniture, fabrics, works of art, flooring and, even decorative wall paint fade with time (some more than others).
Here are some tips from the pros:
Wood: Natural wood finishes are much more stable than stains or finishes which alter the color of the original wood. And, wood may actually darken with prolonged exposure to UV rather than fade to a lighter color.
Fabrics: Results differ depending upon fiber type, dye color and stability and/or pattern printing techniques. Fabric cost has no bearing on the degree of fade damage and expensive fabrics may be as vulnerable to
fading as less expensive fabrics.
Artwork: From photographs to paintings, tapestries to wood sculptures, certain media will fade more rapidly than other works of art. A watercolor, for example, is far more vulnerable than an oil painting. A tapestry of bright bold colors may deteriorate more rapidly than a solid wall hanging. To be safe, never place art in direct sunlight.
Occupants: The sun’s harmful UV rays damage more than furniture and fabrics, this is why The Skin Cancer Foundation recommends the use of Window Film as a device for the protection of skin.
