In construction, glass is often classified by type: the way it is manufactured or further processed. Each type has its own characteristics that determine what it is suited for. Below are the most common types.
Application
Float glass
The base glass poured onto molten tin, giving a flat, clear surface. It is the raw material for nearly all processed glass types.
Toughened (tempered) glass
Float glass that is heated and rapidly cooled, making it several times stronger. On breakage it disintegrates into small, blunt granules. A form of safety glass.
Laminated glass
Two or more glass sheets bonded with a tough PVB interlayer. On breakage the fragments stay attached to the film, preventing injury and fall-through.
Wired glass
Glass with an embedded metal wire mesh. It holds fragments together on breakage and was traditionally used where some cohesion was desired.
Figured glass
Glass with a relief pattern in its surface. It transmits light but limits visibility, providing privacy.
Insulating glass / double glazing
Two or more panes with a gas-filled cavity between them, for better thermal insulation than single glass.
Mirror glass
Float glass with a reflective metal layer on the back, used for mirrors and decorative applications.
Curved glass
Glass bent in a kiln over a mould into a curved shape, for example for round facades or display cases.
