Clear Soda-lime Glass

Soda-Lime type float glass is the standard glass utilized in windows, doors, mirrors and most architectural applications. Available in standard thicknesses, it is readily available and relatively inexpensive. It offers advantages over plastics such as acrylics and polycarbonates in clarity, scratch-resistance, flatness and rigidity. The glass is produced by “floating” the glass on a bath of molten tin and mechanically manipulated to produce the right thickness.

For industrial applications, IGT utilizes glass from several float manufacturers, inculding AGC (AFG), Pilkington, PPG and Guardian. The float process for glass manufacturing was invented by Sir Alastair Pilkington in 1952. For an explanation of the float glass manufacturing process, click here.
