Building glass is the collective term for all types of glass used in construction, from simple float glass to high-performance triple-glazed insulating glass and structural glass. Glass is one of the most versatile building materials: it transmits light, insulates, protects and can even serve a load-bearing function.
Types of Building Glass
The main glass types in construction:
- Float glass — the standard flat glass, the basis for all further processing
- Toughened glass (tempered) — four to five times stronger than ordinary glass; breaks into small granular pieces
- Laminated glass — two glass panes with an interlayer film; holds together when broken
- Insulating glass (double/triple glazed) — two or three panes with an insulated cavity
- Wired glass — glass with an embedded steel wire mesh, fire-resistant
- Enamelled glass — coloured or printed glass for cladding
Application
Building glass is used throughout construction:
- Windows and doors — insulating glass for thermal and acoustic performance
- Cladding — structural glazing with bonded glass panels
- Balustrades — toughened or laminated glass as a transparent guard
- Rooflights — domes and roof lanterns
- Floors — walk-on laminated glass in voids and atriums
Selection Criteria
- Thermal insulation — U-value of the glazing unit
- Solar control — g-value (solar heat gain coefficient)
- Security — burglar resistance and fall protection
- Acoustics — sound insulation near busy roads
