Myth – Window Film will stop fading of interior furnishings 100%
Reality – While window film does a tremendous job in reducing the amount of fading caused by harmful UV rays (blocking 99% or more), solar heat (cutting up to 82%), and visible light. It cannot eliminate 100% of the deteriorating effects of the sun. Window film is an effective solution to reduce fading in comparison to untreated glass.

Myth – Window Film will ruin the view
Reality – Although a dark or reflective film may reduce the view from the outside looking into a car, home or office, the same is not true when looking from the inside out. This is due to Visual Acuity where the human eye adjusts to the amount of light it is receiving, enabling you to see outside, even when the light transmission has been reduced.

Myth – Security Film is bullet resistant and hurricane proof
Reality – Many companies claim that security window film will protect glass from such extreme forces such as hurricanes and even bullets. The tests used to promote these claims are often conducted using ½-inch thick glass and multi-layers of security film—both uncommon situations. Most installed glass is 1/8-inch to ¼-inch thick in general. No window film can stop a bullet on standard glass. In addition, “hurricane proof” is a complete misnomer. If a hurricane can rip open a roof, it only makes sense it can destroy a glass window as well. Security level window film is designed to reduce injury and damage by holding glass together after it breaks.

Myth – All Automotive Window Film is illegal
Reality – Laws vary from state to state, and country to country. In the U.S., window film is prohibited on the front windshield but permissible on the rear side windows and back windshield. The amount of allowable light transmission varies depending on state laws. Many countries allow window film on the entire car as long as they meet certain light transmission standards. Consult with your Johnson Window Films’ professional to stay within legal boundaries.

Myth – Anyone can install window film
Reality – Installing window film may look relatively easy but there are many circumstances that could lead to an unprofessional installation. It is very easy for the film to become contaminated with dirt, dust or hair, thus ruining the film and creating dissatisfaction. A professional installer is experienced with proper preparation and application techniques to prevent contamination or other problems with the film, and ensure a quality installation.
