Ordinary transparent glass

Introduction to Ordinary Transparent Glass

Ordinary transparent glass, commonly referred to as float glass or soda-lime glass, is the most widely used type of glass in the construction and decoration industries. It is produced by floating molten glass on a bed of molten tin, resulting in a perfectly flat, clear, and distortion-free sheet. This material is the foundation for windows, doors, display cases, and countless architectural elements. Its primary characteristics include high light transmission (typically over 85%), moderate thermal insulation, and excellent recyclability. While it lacks the safety features of tempered or laminated glass, its affordability and versatility make it the default choice for general building applications. The global market for ordinary transparent glass is driven by urbanization, infrastructure development, and the renovation of existing buildings.
