The decorative layer of laminate uses printed inks that are subjected to rigorous light-fastness testing. While these inks are formulated for long-term stability, they are not entirely impervious to the effects of ultraviolet radiation. Over years of heavy, direct sunlight exposure, the decorative film may experience subtle color changes. To protect the original appearance, it is standard practice to utilize curtains or UV-blocking window films to mitigate direct sunlight from hitting the floor continuously.
