Low-E (low-emissivity) energy-saving glass is a type of coated glass featuring multiple layers of compound dielectric materials, as well as functional and non-functional metallic thin films, applied to its surface. This configuration ensures high transmittance for visible light while providing high reflectance for infrared radiation. Jinjing has introduced an off-line Low-E coating production line from Leybold Optics (Germany) with an annual capacity of 20 million square meters, enabling the company to supply customers with high-performance triple-silver, double-silver, and single-silver Low-E energy-saving glass.
