Frequently Asked Questions, Learn More About Tinting

GT Tint receives many frequently asked questions from our customers and we hope this page will help to answer some of your questions so you can learn more about tinting.

What are the benefits of window film?

Some of the benefits include:

  • Up to 99% Ultraviolet (UV) light reduction
  • Reduced fabric/textile deterioration
  • Reduced exposure to UV radiation
  • Increased shatter resistance
  • Resistance from scratches

How long will film last?

The effective life of window film will vary with the type of film, type of glass, window construction, compass orientation of glass and geography. All quality window films for use are under warranty by the film manufacturers for a minimum of five years (certain products may have extended coverage).

How should I clean my windows after film is applied?

Windows with film applied are easily cleaned without damage as long as a few common-sense guidelines are followed:

  • Use a soft clean cloth, soft paper towel, or clean synthetic sponge.
  • Use a soft cloth or squeegee for drying the window.
  • Use any normal glass cleaning solution which contains no abrasive materials.

The availability of scratch-resistant coatings as a standard feature of quality films has virtually eliminated the need for extra special precautions in cleaning.

Will window film kill my house plants?

In most cases if a house plant is already receiving adequate light, the use of window film will not harm it. New growth or flowering may be delayed and a plant may go into a state of shock while it adjusts to the light change. If a particular plant normally wilts by the end of a sunny day, it will actually thrive better with film installed.

Will window film really stop fading of fabrics?

No. Window film cannot eliminate fading. It can, however, offer maximum protection from fading due to solar ultraviolet light and solar heat.

Can Window Film be used on Low E windows?

Whether window film should be used on Low E windows and how much you will benefit depend on three factors:

  • Type of low E surface used on glass.
  • Location of low E surface in the window system.
  • The desired amount of heat gain reduction, heat loss reduction, or other film benefits.

If there is any question about the type you may have, ask your glass company or the window manufacturer to send you specific information about your glass. The type of window film you choose for low E glass depends entirely on your desired benefit -whether you want to reduce heat gain, control glare, prevent heat loss, reduce fading or enhance the safety of your windows and glass doors. Carefully consider all these benefits before making a final decision.

Will window films cause glass to break?

Glass breaks when stressed. There are five types of stress which may cause glass breakage:

  • Thermal Stress--from absorption of solar radiation.
  • Tensile Stress--from the weight of the glass itself.
  • Mechanical Flexing Stress--from wind.
  • Impact Stress--from flying objects, hail, baseballs.
  • Twisting Stress--from building or window frame sagging or settling.

The first type, thermal stress, is the only one which film may affect. The use of window films will increase the thermal stress on sunlit glass.

However, there are also other factors which will increase thermal stress such as: partial shading of windows from overhangs, tightly fitting drapes or blinds, signs or decals on windows and heating and cooling vents directed at glass. In addition, different types of glass (annealed versus tempered, clear versus tinted) have different solar absorption rates and will withstand different degrees of thermal stress. If you are ever in doubt, you should request a copy of such guidelines from your manufacturer.
