What is window film?

Window film is an adhesive layer that can be applied to your glass windows. Window tint is used to:

How does a transparent window film do all that?

The answer lies in the science of reflection and transmittance of light. Energy travels from the sun to the earth and through our windows at different wavelengths. Solar radiation can be broken down into 3 types of light based on these wavelengths:

  • Visible light
  • Infrared light
  • Ultraviolet light

Visible Light

Visible light refers to the light we can see. In many cases, our clients want to preserve visible light to maintain the aesthetic appearance of the glass. They don’t want their glass to appear tinted as a result of window film application. But some clients don’t mind the tint because it provides better results.

Window film products are designed to allow varying levels of visible light transmission (VLT). The higher the VLT of the window film you select, the more visible light is transmitted through the window. And the more optically clear the window film will be.

Infrared Light

Infrared light comprises over half of the total energy from the sun. Infrared light is not visible to the human eye but is part of the solar radiation that we feel as heat. Window films are designed to block transmittance of infrared light in order to provide optimal heat rejection. It also helps to maintain comfortable interior temperatures without the cost.

UV Light

The smallest fraction of the sun’s light travels to the earth in the form of ultraviolet light. UV light has been identified as a leading cause of skin cancer. Sun exposure is the primary cause of floors and furniture fading. Because of the damaging effects of UV light, 3M has engineered window films that block up to 99.9% of UV light. This happens without any change to the visual appearance of your window.
