Solar window screens intercept some of the sun’s rays as they hit your windows, reducing the amount of light and heat coming into your house. The reduced heat load coming through the windows lowers your cooling bill. In addition to energy savings, solar screens block much of the ultraviolet radiation that causes fading and damage to textiles. Solar window screens also reduce glare, thus making reading or watching television more enjoyable. Finally, the screens provide a degree of privacy during the day because they are darker and heavier than normal screens.
