Will 3M Window Films stop my furniture from fading?
Nothing completely stops fading. 3M Window Films are designed to
help reduce the major causes of fading (ultra violet light, visible
light, and solar heat), thus prolonging the life of your furnishings,
perhaps as much as two to five times.
Keep in mind the article(s) to be protected; if they have a typical
life of five (5) years then they may last ten (10) years to much longer
depending on the performance of the film selected. However, if the
typical life is only 2-3 weeks, then the expectation should be expressed
in terms of months.
As a general rule of thumb, ultra violet (UV) is approximately 40%
of the cause, visible light is about 25%, and solar heat about 25%. The
remaining 10% can be attributed to humidity, pollutants, interior
lights, dye stability, and more.
