All around the world there are different types of climates and Solar Window Screens work well in all. For instance, in the western United States most residents experience a dry, hot heat versus the hot, humid heat of the southern United States; however, heat is heat and it is much less expensive to use them of all the options available on the market today.
A sun blocking shade improves air-conditioning efficiency by stopping up to 90 percent of the sun's heat before it penetrates your window's glass surface! My supplier only has the charcoal gray in stock but that works well for us here in Florida because many of our windows are tinted charcoal gray.
As you'll see in the video, installing is a snap! The best part is that clients have told me that since the screens went in, they haven't had to set the air conditioning thermostat as low! Now that's results!
