The summer sun can be brutal, especially in the south. Sunscreens for windows offer a superior way to help prevent the sun from heating up your home and increasing your cooling costs. The screens are mounted to the exterior of the window and prevent a large portion of the sun from even touching the glass, unlike window tints, which are applied to the interior and actually allow the glass to soak up sun rays and increase the temperature of your interior space. The screens are constructed of durable material and will last for many years. They are attractive from the exterior and offer high visibility when viewing out from inside your home. Most screens will come in options that will allow you to block 80% to 90% of the suns rays. The cost of the screens and installation are well worth the investment and will quickly pay for themselves in electricity savings and increased comfort.
