Sun Control Window Film is a piece of polyester with metallic coating that reflects solar radiation. Metals commonly used as coating are titanium, silver, bronze, nickels, etc. The effectiveness of a window film in heat rejection is reflected in its Shading Coefficent (SC). The lower the SC value, the more the effective the solar heat rejection.
In the new generation of Sun Control window, no metallic coating is required in the polyester sheets. By using multi-layer optical film technology, films can provide more or less same heat rejection but with much higher visibility (high VLT)
