Which process is used to produce glass used in regular windows?

The process used to produce glass for regular windows is the float method, which involves creating a smooth, flat surface essential for window applications. In this technique, molten glass is poured onto a bed of molten tin, allowing the glass to spread out and form a uniform thickness due to gravity and surface tension. This results in a high-quality surface finish that is vital for windows, as it ensures clarity and minimizes distortions when looking through the glass.

While there are other processes for producing glass, the float method is particularly favored for its efficiency and the superior quality of the final product, making it the standard choice for window glass manufacturing. The other processes, such as draw, sheet, and cast, may produce glass but are typically used for different applications and do not yield the same level of optical clarity and flatness that float glass does.
