We just had new real hardwood floors installed and my friend was telling me that I need blinds or drapes to protect my floor from the sun. We live in a private area, so I have no window coverings at all and I love the natural light. I hate to spend the money if I don't have to since I have a lot of windows, but I don't want to ruin the floors either. Someone else told me that the sun won't damage the floors, but just add character so now I don't know what to believe - help!
