Low-emissivity (Low-E) coated glass is produced by depositing layers of low-emissivity materials such as silver and metal oxides onto the surface of the glass, which gives the glass a distinct appearance in various colors.
This coating significantly reduces the U-value of the glass while selectively lowering the shading coefficient (Sc), thereby enhancing the glass’s energy-saving performance.
Key features include:
High infrared reflectance: Effectively reflects far-infrared thermal radiation, reducing heat transfer.
Low surface emissivity (E): Minimizes the absorption of external energy and reduces the re-radiation of heat.
Wide Sc range: Allows flexible control of solar energy transmission, making it suitable for varying climate and energy-efficiency needs.
