Window film technology
Solar Film
Solar film is the umbrella term for window film engineered to reduce solar heat gain, regardless of underlying chemistry (dyed, carbon, ceramic, sputtered or multi-layer).
In Singapore the term "solar film" is often used interchangeably with "window tint," but technically solar film refers to any film optimised for solar control — heat, UV and glare — rather than for privacy, security or decoration.
A film labelled "privacy tint" might be a dyed product with low VLT but mediocre heat rejection. A film labelled "solar film" should always quote total solar energy rejection and IRR.
When comparing quotes from different workshops, ask each one to specify whether the product is dyed, carbon, ceramic or multi-layer, and ask for the full heat-rejection spec sheet. Solar film is a category; chemistry is the differentiator.
