I have a substantial amount of Tiger Wood hardwood installed in my house. The sun has turned much of it to a bleached out birch look colour. The sun exposed areas gradually go from the bleached birch color to the darker tiger wood color as you go away from the window exposure. This floor has been down for 9 years and is a Mirage product. I also have a different brand of tiger wood installed in my master bedroom which has large windows in there is no bleaching effect. Has anyone else experienced his problem?

I've seen it on many different floors even though they say it's UV protected it can only do so much. Depends on the amount of light coming through the windows and the direction. A UV film on the windows helps a lot.

Even a light bulb will lighten a floor over time.
