Both financially and emotionally, you’ve made a tremendous investment in your home or office. Once that investment is made, the next step is keeping it looking beautiful. Unfortunately, fabrics, wallpaper, natural wood floors, photos, and other valuables will fade when unfiltered sun shines through your windows.
Fading is caused by four reasons:

Ultraviolet (UV) light is the primary cause of fabric and furniture fade. All 3M window films block up to 99.9% of UV light.
Not only does UV light contribute to fabric fade, but so do visible light (25%) and heat from the sun (25%). 3M tinted window films help block out visible light and heat to minimize your fabric fade.
“Other” (10%) refers to variables that are beyond your control - such as the color or material of your furnishings. Simply put, some fabrics and materials maintain their color longer than others.
