How does solar film work?



Window film is a self-adhesive polyester film that is applied to glass surfaces. It is used as a retrofit application for existing 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:

1. Visible light that we can see

2. Infrared rays that we can feel as heat

3. Ultraviolet (UV) rays which are invisible.

As solar radiation strikes a piece of glass, window film acts as a screen 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.


Cost-effective

Utility bills in Hong Kong can get expensive during the summertime but as we all know, it’s a necessary to keep the inside of your home cool and refreshing. Solar film for home windows helps minimise the dependence on air conditioners by reflecting infrared rays and ultraviolet rays and are a quick, easy, and inexpensive way of reducing energy costs.


An inexpensive alternative

Blinds and curtains may help protect you and the furnishings you own from the sun, but they obstruct outside views and prohibit you from enjoying natural light. This is not the case with window film. Solar window films not only reflect harmful rays from penetrating your windows but allow a regulated quantity of natural light to enter your home. In addition, you can say goodbye to the daunting task of cleaning and dusting involved with blinds and curtains.


An energy-efficient solution

Air conditioners require a large amount of energy to operate properly, especially during the summertime. Solar window films are a great alternative for keeping your rooms cooler while minimising the energy used by the air conditioners - and in turn reduce those dastardly bills too! They help make your home more energy efficient, which is a mutually beneficial situation for both you and the environment.
