All Spec Sun Control is a window film that works with your windows to provide a high level of security and protection for both your home and office. The film is applied to the window, and in the event that the window breaks, the glass will remain in place. Windows will not shatter in or out, preventing injury from flying shards of glass. It also deters break-ins because it makes it time-consuming and difficult to break through the window. Visit the website today!
