Types of glass and their uses
Short answer
Soda-lime glass is used for windows and bottles. Float and plate glass suit distortion-free glazing. Toughened glass is for doors and railings; laminated for safety glazing and windscreens. Wired glass offers fire resistance; borosilicate for labware; glass wool for insulation; insulated glass for energy saving; glass blocks for walls and lighting panels.
Write down the different types of glass and their uses in the construction field.
Glass is a hard, brittle, transparent material made by fusing silica sand with soda ash and limestone, then cooling it rapidly. Common types:
| Type | Features | Uses |
|---|---|---|
| Soda-lime (ordinary) glass | Cheap, easily moulded, melts at low temperature | Window panes, bottles, doors, partitions |
| Plate glass | Ground and polished flat, distortion-free | Shop fronts, large windows, mirrors, table tops |
| Float glass | Made by floating on molten tin; flat and uniform | Modern windows, facades, glazing |
| Sheet glass | Drawn into sheets; slight distortion | Windows, partitions, glazing in doors |
| Toughened (tempered) glass | Heated and quickly cooled; 4–5 times stronger, breaks into small pieces | Doors, glass facades, railings, stairs |
| Laminated glass | Two or more sheets bonded by a plastic (PVB) layer; stays together on breaking | Windscreens, skylights, safety glazing, bullet-resistant glass |
| Wired glass | Steel wire mesh inside | Fire-resistant windows, roofs |
| Borosilicate (Pyrex) glass | Contains boron oxide; low thermal expansion | Laboratory ware, heat-resistant pipes |
| Glass wool / fibre glass | Fine glass fibres | Thermal and sound insulation, reinforcing plastics |
| Frosted/obscured glass | Etched or patterned surface | Bathroom windows, privacy glazing |
| Insulated (double-glazed) glass | Two panes with an air gap | Energy saving windows, cold regions |
| Glass blocks | Hollow glass units | Walls and lighting panels |
