Southern exposure windows receive good light all year long. A warm glow is cast on the interior. To protect fabric, furniture and floor coverings, light-diffusing treatments can help.

Western exposure windows admit the hottest, haziest light of the day. Consider a combination of light diffusing and light blocking treatments.

Eastern exposure windows offer warm, bright light, especially during the morning hours. Treatments that block UV rays are a good choice.

Northern exposure windows offer the clearest, most consistent light and the coldest exposure. The use of energy-efficient treatment will help control energy costs.
