SunScreens are beneficial even if you already have reflective light-colored drapes or blinds. Along with the heat that is absorbed by drapes or blinds, they are also subject to UV damage. The combination of light-colored interior shades and dark exterior screens will provide the best results. Sun control screens are more effective than glass tinting for energy savings because as the glass filters sunlight through the tint, it maintains heat, which dissipates into the house.

While UV blockage is 65 percent to 90 percent, actual visibility is diminished by only 15 percent to 40 percent depending on the screening fabric selected. Light through the SunScreen is not tinted but is reduced in volume, allowing good light with reduced glare to protect carpets, drapes and furniture from damaging UV rays, sunscreens should remain on windows and doors even during cooler months.

The EPA ( Environment Protection Agency ) considers them to be an insulating addition to your home and your power company considers them to be energy savers.

Some years, both the EPA and your power company give rebates on your income tax report or electric bills.
