Why You Need Window Film

A brief run down of the key product benefits to understand why window film is the right choice.
How it Works – Basic understanding of what window film is made of and how it performs when applied to glass.

At Tint City, we break it down to basically 7 Reasons Why to Choose Window Film:

  • Decrease Heat – Window film is the most efficient way to reduce unwanted solar heat transferring through your windows. It can provide up to 78% heat reduction versus untreated glass, while controlling hot spots and cooling off sun-drenched areas in your home or office.
  • Reduce Fading & Health Risks – Window film blocks up to 99%* of UV rays, while also significantly reducing heat. This helps to protect your valuable furnishings from fading and provides a “sunscreen”for your skin against the harmful effects of the sun.
  • Cut Glare – Whatever the cause – direct sun, reflections from snow, water or surrounding buildings – there is a perfect window film solution to help reduce annoying glare.
  • Enjoy Energy Savings – Reducing temperature imbalances caused by extreme sunlight is why so many designers, architects and building engineers desire window film. Reducing heat loss will increase HVAC efficiency and lower energy costs.
  • Increase Safety – Accidents, environmental effects and vandalism can instantly turn a pane of glass into life-threatening shards. Window film can act as a “safety net” by holding shattered glass together.
  • Enhance Appearance – Whether it’s a contemporary look or a uniform design, there’s a choice of window film products that can aesthetically complement the exterior of a home or office building.
  • It’s Fast and Easy – Professional installation is quick and simple. There’s minimal disruption to one’s daily lifestyle or work schedule.
How it Works

Basic understanding of what window film is made of and how it performs when applied to glass.
Window film is basically a self-adhesive polyester film that is applied to the interior surface of glass. It’s used as a “retrofit” for existing glass on automobiles, homes and commercial buildings in order to upgrade solar control and safety.

Solar radiation from the sun is divided into 3 components; visible light we can see, and infrared and ultraviolet rays which we can only feel. As solar radiation strikes a piece of glass, window film acts as a “sunscreen” to block harmful UV rays as well as regulates the levels of heat and light passing through the glass. The amount of heat and light rejected is all dependant on the type of window film selected

There are basically two types of window film – non-reflective or dyed films that primarily absorb solar energy, and reflective or metallized films that absorb as well as reflect solar energy.

Care & Maintenance

Important tips on how to take care of a glass window with film to ensure product longevity.

Once window film has been installed, it’s 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.

Once the film is dry and cured, it’s then safe for the film to be cleaned. The best cleaner is a simple solution of water and a small amount of soap. Clean the window and then squeegee dry with overlapping strokes in the same way you would clean the outside of your car windows. You may also clean the film surface with any normal strength glass cleaner. Products with amonia willnot damage the film if used in reasonable quantities and if the film is not left to soak in it. Do not use any abrasive cleaners, industrial strength glass cleaners and/or any other window cleaning tools that may scratch the window film. Remember, the surface of the film is coated with a scratch resistant not scratch proof coating.

Myth vs. Reality

There are many misconceptions surrounding window film. This page will set the record straight.

Myth: Window Film will stop fading of interior furnishings 100%
Reality: While window film does a tremendous job in reducing the amount of harmful UV Rays (up to 99%) and solar heat (up to 78%), it will not completely eliminate the deteriorating effects of the sun, especially over a long period of time. However, window film is significantly better at stopping fading in comparison to untreated glass.

Myth: Window Film will ruin my view
Reality: Although a dark or reflective film may reduce the view from the outside
looking into a car, home or office, it does not mean the same optical restrictions apply from the inside looking out. This is due to Visual Acuity where the human eye basically adjusts to its light surroundings and stabilizes sight enabling an unrestricted sight, even when the light transmission has been reduced by up to 70%.

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 natural disasters and even bullets. The tests conducted often times use ½” glass and multi-layers of security film–both unrealistic situations in today’s market. And “hurricane proof” is a complete misnomer. If a hurricane can rip open a roof, it only makes sense it can destroy a thin piece of glass window as well.

Myth: All Automotive Window Film is illegal
Reality: Laws vary from state to state, and country to country as to what types of window film are allowed. 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 around the world allow window film on the entire car as long as they meet certain light transmission standards. It’s important to check with your dealer to ensure your film installation is legal.

Myth: Anyone can install window film
Reality: Window film installation may look relatively easy but there are many circumstances that could lead to a poor installation. It’s very easy for the film to become contaminated, thus ruining the film and creating dissatisfaction. A professional installer is experienced with many techniques to prevent problems with the film, and ensure a proper and quality installation.

Variety of Usage

People utilize window film for a number of different reasons. Find out the many ways to use window film.

Solar Control

One of the primary reasons people choose to add window film is to control the negative affects of the sun such as heat, glare and fading. By minimizing heat, window film can provide a more comfortable and enjoyable environment for car, home and office workers. Annoying glare is reduced allowing for more pleasant scenic view and a less dangerous driving environment. And interior furnishings are better protected from the dangerous rays of the sun.

Style & Appearance

There are a variety of window film shades or colors that can enhance the look of a car window as well as compliment the design of a home or office. Window film can also provide additional privacy as well. Check with your local dealer to find the style suitable for your needs.


Accidents happen very often to glass and can create a dangerous situation, especially in residential homes with children. Safety film effectively holds glass together and prevents dangerous shards from flying when the glass is broken.


Thicker security films are available to help prevent vandalism and theft. While security films cannot entirely stop someone from breaking through glass, the thickness of the film makes it more difficult and time consuming for vandals to complete their act.

Anti Graffiti

Glass is expensive to replace. So many commercial owners choose easy-to-move anti-graffiti film to protect their glass from damaging graffiti and glass etching.

How Window Film Affects Glass

Understand what happens when solar radiation strikes a glass window installed with window film.

Glass is designed to be a barrier from exterior elements (i.e. wind, rain and snow) while providing a natural view of the outside world. When solar energy – comprised of heat, light and UV Rays – hits a glass window almost 90% of the energy is transmitted through.

When window film is applied to glass, its properties including special dyes and/or metals incorporated within the film act as a solar energy barrier either by absorbing part of the energy or reflecting a portion of the energy away from the glass.

The level of absorption and reflectance is dependant on how the film is constructed. Dyed films contain no metal and are considered non-reflective because they only absorb solar energy. They are not as effective in controlling solar heat and light because they do not provide any solar reflectance. On the other hand, metallized films provide both solar absorption and reflectance. They do a much better job of solar control since the metal properties within the film reflect both heat and light away from the glass surface.
