Furniture, fabrics, and other interior fixtures, as well as valuable paintings and papers, will fade over time. The main contributors to fading are ultraviolet (UV) radiation, visible light, absorbed heat and moisture. Most laminated glass interlayers are formulated to screen out UV radiation below 380 nanometers (nm). The UV filtering characteristics in the laminate interlayer enable laminated glass to reduce the rate of fading and deterioration of these materials.
