What Does Film Do?

  • VLT or Visible Light Transmitted is  how dark the tint appears to be, ie 3M's FX-30 will have a VLT of ~30%
  • TSER or Total Solar Energy Rejected simply put is how much heat is absorbed by the film
  • VLR or Visible Light Rejected is just that, 'light rejected.' mirrored reflective films will have a higher percentage of VLR compared to dark hued films

What is window film?

Window film is a laminate of strong polyester and/or metalized coatings bonded by adhesives. There is a scratch resistant coating on one side, and a mounting adhesive layer and a protective release liner on the other side. When the release liner is removed, the side of the film with the adhesive is applied to the interior surface of the glass.

How does window film work?

Solar radiation from the sun is divided into three components: visible light we can see, and infrared and ultraviolet rays that we can only feel. As solar radiation strikes a piece of glass, window film blocks UV rays to regulate the level of light and heat that passes through. The amount of heat and light rejected is all dependent on the type of window film selected.
