Hello Jaydine Rendall, our product is completely safe to use in indoor spaces even with direct sunlight. Windows create a protective barrier that keep the countertops safe. If you have any further questions, please contact Cambria Customer Care at 866-226-2742.

I have cambria in my kitchen which gets direct sunlight all day long. My island is a white marble looking cambria and perimeter counters are dark grey. No fading at all in 4.5 years and I LOVE them. I have honed granite in other areas and quartz in master bath and kitchen. Quartz is so much easier to keep clean.
