What type of glass is used for handrails?

Edited by: Viewmate All Glass Railing

Glass handrails require specific safety glass engineered for strength and impact resistance, rather than standard window glass. Two main types dominate the market.

Tempered Glass

Tempered glass undergoes heat treatment, which makes it approximately five times stronger than regular glass. If it breaks, it fractures into small, blunt granules instead of sharp shards, significantly reducing the risk of injury. This is the most common choice for residential handrails, typically with a thickness of 10mm to 12mm. It is suitable for decks, ground – level balconies, and interior applications.

Laminated Glass

Laminated glass consists of two or more glass layers bonded with a plastic interlayer, usually PVB or SentryGlas. Even if the glass cracks, the interlayer holds everything together, preventing dangerous falls. This makes it the necessary choice for elevated installations such as high - rise balconies, staircases, and pool areas where failure is not an option. Common configurations include 6+6, 8+8, or 10+10 construction.

Which One to Choose

For ground - level decks and patios, high – quality tempered glass offers excellent safety and value. For elevated balconies, stairs, or anywhere a fall would be dangerous, laminated glass is the wiser, often code - mandated choice. Both types meet safety standards when properly certified and installed by professionals who understand local building requirements.
