Even though it is winter you should still protect your carpet from the sun’s damaging rays. Prolonged exposure to sunlight will cause a bleaching effect and will change the color of your carpet and furniture.
Sunlight damage to carpet can be prevented by drawing blinds, shades or heavy drapes when the sun is shining directly on your carpet. You can also purchase UV resistant types of carpet but drawing the shades is the best form of preventing sunlight damage to your carpet.
There are also special types of window film that you can apply directly to the window that blocks the ultra violet rays but allows other light through. Using window film is a great way to let in light and stop the suns damaging rays from bleaching your carpet and furniture.
If replacing your windows is under consideration, many windows now have UV protection built in. Ask your dealer or contractor about windows with UV protection.
