How Film Works

What is Window Film?

Vista Window Film is a laminate of strong polyester and metalized coatings bonded by adhesives. A scratch resistant coating is applied on one side; a mounting adhesive layer and a protective release liner are applied to 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. Film can be clear, colored, or patterned to blend with various design schemes. Various thicknesses are available for solar, safety, or security applications.

How Does Window Film Work?

Solar radiation from the sun is divided into 3 components; visible light we can see, and infrared and ultraviolet rays which we can only feel. As solar radiation strikes a piece of glass, window film blocks harmful UV rays and regulates the levels of heat and light passing through the glass. The amount of heat and light rejected is all dependant on the type of window film selected.

Energy-saving window film enhances the solar and thermal performance of a building's windows. It does this by reducing excessive solar heat gain – reducing cooling loads and peak demand. In addition, low emissivity (or low-e) films improve the insulating properties of windows – offering increased cooling season savings and the added advantage of heating season savings.
