Once window film has been installed, it is very common to see a slight haziness and/or small water pockets. This is a normal part of the adhesive bonding process called "curing". Depending on the film type and weather conditions, it may take up to 30 days for the film to be fully cured. The curing process is slow because the remaining water used in installation must evaporate through the film. Sputtered and heavy security films take the longest to dry and will take longer for any hazy appearance to disappear.
Window film is a self-adhesive polyester film that is applied to glass surfaces. It is used as a "retrofit" application for existing glass on automobiles, homes and commercial buildings in order to upgrade solar control, safety and appearance. Solar radiation from the sun is divided into 3 components: visible light we can see, infrared we feel as heat and ultraviolet rays, which are invisible. As solar radiation strikes a piece of glass, window film acts as a "sunscreen" to block harmful UV rays as well as regulate the levels of heat and light passing through the glass. The amount of heat and light rejected is dependent upon the type of window film selected.
Glass is designed to act as a barrier from exterior elements (i.e. wind, rain and snow) while providing a natural view of the outside world. When solar energy or sunlight, comprised of heat, light and UV Rays hits an untreated window, almost 90% of the energy is transmitted through the glass. In contrast, once solar control window film is applied to glass nearly 80% of solar energy can be blocked. The special dyes, metals or nano technology within the film, act as a solar energy barrier by either absorbing or reflecting a percentage of the energy from passing through the glass.
One of the primary reasons people choose to add window film is to control the negative effects of the sun such as heat, glare, UV damage and fading. By minimizing heat, window film can reduce A/C costs and increase comfort in your car, home and office. Glare reduction helps to improve visibility, and reduces eyestrain. Rejecting UV rays helps to protect your skin and eyes from damage and slows fading of interior furnishings, carpets, artwork and other valuable belongings. There are a variety of window film shades or colors that can enhance the look of a car window as well as complement the design of a home or office. Window film can also provide additional privacy as well.
