Part 1: Window Film Basics

What is window film?

Window film is a coating made of polyester that is applied to glass. Its primary use is to decrease the amount of sunlight that passes through the glass. When used in vehicles, it is commonly known as window tint. (Please note that we do not provide services for automobiles.)

All types of window film are made from a polyester base material. The base material is produced from a polymer called Polyethylene Terephthalate, commonly known as PET. PET is synthesized by combining terephthalic acid with monoethylene glycol, both of which are derived from petroleum.

What are the benefits of window film?

  1. Energy Savings
  2. Enhanced Appearance 
  3. Safety and Security
  4. Fading Reduction
  5. Glare Protection
  6. Temperature Imbalances
  7. Privacy
  8. More affordable than window replacement


Window Film Types:

Reflective Film: Reflective film is the most common type of window film in residential and commercial settings. This type of film absorbs and reflects the energy from the sun and other light sources that would normally pass through glass.

Dual Reflective Film: Dual reflective film works much in the same way that ordinary reflective film does. The primary difference is that this film absorbs the energy passing both ways through the glass. This means that both the amount of light traveling into and out of the applied window is reduced.

Neutral Film: This film reduces the amount of heat entering a home without changing the look of windows. This helps to reduce cooling costs without sacrificing the amount of natural light coming into your home.

Spectrally Selective Film: The spectrally selective film differs from the more conventional solar film. The chemistry rejecting solar energy does not use shading or reflectivity visible to our eyes. These films have been engineered to allow the maximum transmission of visible light while rejecting the maximum amount of UV and infrared wavelengths. This results in a product that begins by not impeding our view of the beautiful landscape we have invested in. It improves our visibility of the landscape by reducing glare.

Insulating Film: Conventional applied solar control window film reduces solar heat gain and decreases cooling energy use. However, it fails to take full advantage of the sun’s warmth in cold weather, offsetting summer energy savings with increased winter energy use. Low-E window film combines the solar control functions of a standard film with the insulating power of low emissivity (Low-E) coating. Previously, this benefit has been available only as part of a factory-produced unit. Adding insulation, which improves efficiency in all seasons, compensates for diminished solar heat gain in the colder months

Safety and Security Film:  In addition to films that protect from light and heat, films are also available to protect from accidental or intentional impact by a foreign object.  While glass may still break after an impact from an object, the film can help to prevent shattering and keep the glass in place. In the event of a storm or an earthquake, this reduces the risk of injury due to flying glass. In the case of a home invasion, criminals may be deterred if a window or glass door does not immediately break.

Anti-Graffiti Film: Commercial, industrial, and government facilities can benefit from anti-graffiti film. This film can help reduce the time and resources needed to remove graffiti manually.

Decorative Film: These can be used to add patterns to windows or even increase the privacy of a home or office building. Frosted or colored window tints can provide privacy while also being an appealing addition.
