Sun blocker screens, or solar screens, protect your house windows from the sun’s rays, much like the shade of a tree, but without obstructing the view. These sun screens for windows can be customized to beautifully fit the exterior side of each window on your house. The best benefit of these solar screens is the money you will save on the air conditioning bill because of the UV rays that will be prevented from entering your home. Solar screens absorb about 80-90% of the sun’s heat and filter it away from your home, keeping the temperature inside cool and comfortable.
