Window film is a self-adhesive polyester film used as a “retrofit” application for glass on homes and commercial buildings in order to upgrade solar control, safety and appearance.

Solar radiation from the sun is divided into 3 components: visible light we can see, infrared we feel as heat and ultraviolet rays, which are invisible.

As solar radiation strikes a piece of glass, window film acts as a “sunscreen” to block harmful UV rays as well as regulate the levels of heat and light passing through the glass.

The amount of heat and light rejected is dependent upon the type of window film selected.

Glass is designed to act as a barrier from exterior elements (i.e. wind, rain and snow) while providing a natural view of the outside world.

When solar energy or sunlight, comprised of heat, light and UV Rays hits an untreated window, almost 90% of the energy is transmitted through the glass.

In contrast, once solar control window film is applied to glass nearly 80% of solar energy can be blocked.

The special dyes, metals or nano technology within the film, act as a solar energy barrier by either absorbing or reflecting a percentage of the energy from passing through the glass.
