Do Low-E glass coatings prevent furniture and carpet fading?
Furniture and carpet fading occurs when the energy of ultraviolet (UV) radiation alters the chemical structure of dyes and other colorants. Low-E coatings can provide a reduction in UV transmittance. However, in addition to UV light, other causes for fading and color changes might include exposure to humidity, oxygen, visible light and heat. While low-E coatings can greatly reduce fading, it is important to remember that various types of materials (wood, fabrics, paint, rugs, etc.) react at differing fading rates depending on the colorant type and its susceptibility to fading from any of these causes.
