What is Window Film?

Window film, also called window tinting or glazing film, is a thin laminated polyester film that covers any glass surface. The purpose of the film is to change the properties of the window without the costly expense if changing out the glass. Windows are designed to let us view the outside world without experiencing the weather that comes along with it. This means that they are great for keeping us warm and dry, but it also means that it changes the way light enters a space.

Without being too technical, when light enters a new medium, such as glass, some of the energy is reflected, some is absorbed and the rest is refracted. Window film changes how the light (heat and UV rays as well) interact with the glass. It changes the proportions of reflected, absorbed and transmitted light; by doing so it changes how much glare there is in an environment or how much heat and light there is as well.  Different dyes, coatings, adhesives and layering of the films will change how the film performs on the windows.

So why use window film?

Window film is only a small part of the rooms environment but it can have significant impacts on the functionality of the room, especially when used with other elements. Window film can be used to:

  • Reduce Heat and Glare
  • Block UV Light
  • Provide privacy
  • Create a uniform external facade
  • Reduce energy bills
  • Create decorative patterns
  • Safety and security
  • Thermal insulation
  • Comfort

It’s also a cheaper option than replacing your glass every time you want to change how your windows perform. The also have an advantage over elements such as blinds and curtains; they can be completely transparent, allowing for uninterrupted views.
