Flat glass, sheet glass, or plate glass is a type of glass, initially produced in plane form, commonly used for windows, glass doors, transparent walls, and windshields. For modern architectural and automotive applications, the flat glass is sometimes bent after production of the plane sheet. Flat glass stands in contrast to container glass (used for bottles, jars, cups) and fiberglass (used for thermal insulation and optical communication). Most flat glass is soda-lime glass, produced by the float glass process. Other processes for making flat glass include:

• Rolling (Rolled plate glass, Figure rolled glass)
• Overflow downdraw method
• Blown plate method
• Broad sheet method
• Window crown glass technique
• Cylinder blown sheet method
• Fourcault process
• Machine drawn cylinder sheet method
• Plate polishing
  
  

  Plate glass is often used in windows, such as at this cafe in Tel Aviv, Israel overlooking the Mediterranean Sea.
