LOW-E Coated Glass
Low-E coated glass (also known as LOW-E glass) is a film product composed of multiple layers of metal or other compounds coated on the surface of the glass. The product has a high transmittance for visible light and infrared (especially for mid-far infrared) Very high reflectivity, so it has good thermal insulation properties.
Tempered glass is a glass that is heated to a softening temperature and then uniformly and rapidly cooled, so that the glass surface obtains compressive stress. During the cooling process, the exterior of the tempered glass solidifies due to rapid cooling, while the internal cooling is slow.
