My friend has solar screens. What is the difference?
Solar screens are screens, usually black in color, mounted on the exterior of the home. There are various densities of screens, the darker the more heat absorbed. Unfortunately they are not optically clear to look through. They need cleaned periodically, which requires removing and then reinstalling them. They do break down due to the hot sun and inclement weather and will in time need to be replaced. Solar control window film is mounted on the interior panes of glass. Once installed, they are a part of the glass. They are optically clear and are much easier to clean. Since the films are mounted on the interior, they are not subject to inclement weather and will last much, much longer. Unlike solar screens, a wide array of window film choices are available.
