What is toughened glass?
Toughened glass is heat-treated to increase strength. When it breaks, it usually shatters into many small pieces instead of large sharp shards. It is common in shower partitions, doors, shopfronts, table tops, and many window or facade applications.
What is laminated glass?
Laminated glass is made by bonding two or more glass layers with an interlayer. If the glass breaks, the interlayer helps hold fragments together. This makes it useful for railings, skylights, overhead glazing, security areas, acoustic windows, and places where falling glass is a serious risk.
Key differences
- Breakage: toughened glass breaks into small pieces; laminated glass tends to remain bonded to the interlayer.
- Security: laminated glass usually gives better resistance after impact because the panel stays together longer.
- Sound: laminated glass can improve acoustic performance, especially with the right interlayer and glass make-up.
- Overhead use: laminated glass is commonly preferred where broken glass must not fall freely.
- Cost: laminated glass can cost more, but the extra safety may be worth it in critical locations.
Which should you choose?
For a standard door or partition, toughened glass may be enough. For balcony railings, skylights, child-sensitive areas, high-rise openings, or security-focused windows, laminated glass is often the better direction. Many projects also use toughened laminated glass for combined strength and retention.
