Impact-resistant glazing is designed to withstand force without shattering dangerously. It typically includes:
Laminated safety glass
- Multiple layers bonded with an interlayer
- Holds together when broken
- Common in shopfronts and security applications
Toughened (tempered) glass
- Heat-treated for increased strength
- Breaks into small, blunt fragments
- Often used in commercial doors and partitions
The correct choice depends on location, safety requirements, and building code compliance.
Where is impact-resistant glazing used?
Impact-resistant glass is commonly specified for:
- Retail shopfronts
- Commercial entry doors
- Schools and public buildings
- High-wind or high-impact environments
- Areas requiring additional security or vandal resistance
In many commercial applications, impact-resistant glazing is not optional, it’s a compliance and safety requirement.
When is safety or impact-resistant glass required in New Zealand?
Under NZ building regulations, safety glazing is typically required in:

Commercial vs residential impact-resistant glazing
While impact-resistant glazing is used in both residential and commercial settings, commercial applications usually require:

Does impact-resistant glass cost more?
Yes, but it significantly improves safety, durability, and long-term maintenance costs for commercial properties.
