Low-iron glass is a type of glass with a low iron oxide content. It's also known as extra-clear glass and optically clear glass. This optically clear glass increases light transmittance by up to 6%-8%, allowing for increased natural light flow and seamless transitions between spaces.

Anti-reflective glass is made by using a special method to create an anti-reflective film layer on one or both sides of the glass. Compared with the original glass, it greatly reduces the reflection of the glass, and its maximum transmittance can reach 98%.
