In addition, fog is also a key performance indicator, indicating the ratio of scattered light caused by internal or surface tiny particles, bubbles, magazines, etc., to the total light passing through. In general, for the ultra-white rolled glass used for photovoltaics, the fog should be controlled below 1% to ensure good transparency and visual effects.

Glass is primarily a man-made substance.

The float glass process was developed in the mid-20th century by Sir Alastair Pilkington, revolutionizing the glass industry. Prior to this method, glass was produced using labor-intensive techniques that often resulted in irregular thickness and surface imperfections. The float process employs a simple yet ingenious technique where molten glass is floated on top of molten tin, creating a perfectly flat surface as the two materials interact. This unique combination allows for the production of glass sheets with unparalleled uniformity and clarity.

Additionally, the production method—whether the glass is sandblasted, acid-etched, or coated—also affects the price. While standard frosted glass typically comes at a lower cost, unique textures or finishes may increase the overall expense. Installation costs should also be considered, as professional installation can add another $20 to $50 per square meter, depending on the complexity of the job.
