The best type of glass for stairs is tempered laminated glass with a thickness of over 1 inch. This specialized construction combines tempering and lamination processes to create the most secure and durable option for stair treads.
GlassWalk uses 3-ply tempered laminated glass for all stair applications. This engineered system meets building codes and supports live loads of 125 pounds per square foot while spanning up to 56 inches without center support.
Why Tempered Glass is Essential for Stair Safety
Tempered glass undergoes heating and rapid cooling that creates surface compression, making it four to five times stronger than regular glass. This process transforms ordinary glass into safety glass that withstands mechanical stress and thermal shock.
When tempered glass breaks, it crumbles into small, blunt pieces rather than dangerous sharp shards.
Key benefits include:
- Enhanced strength against impact and stress
- Safe breakage pattern that minimizes injury risk
- Resistance to temperature fluctuations
Laminated Glass Technology for Stair Treads
Laminated glass consists of multiple glass layers bonded with polyvinyl butyral (PVB) interlayers. This transparent resin creates a permanent bond that keeps glass layers intact when damaged.
When laminated glass breaks, it develops a spider web cracking pattern while remaining structurally sound. The PVB interlayer prevents dangerous fragments, maintaining stair tread integrity. This automotive windshield technology provides essential safety redundancy for architectural applications.
GlassWalk's 3-Ply Glass Stair Specifications
GlassWalk stair treads feature 3-ply laminated construction with thickness over 1 inch. Each system is engineered and tested to meet building codes, supporting 125 pounds per square foot across 56-inch spans with two-sided support.
The structural design eliminates center supports, creating floating stair aesthetics. Exclusive aluminum brackets hide mounting hardware behind glass risers for seamless installation.
Each system includes stamped drawings for all 50 states and Canada. The framework accommodates custom openings and straight, curved, or spiral configurations. Optional ceramic frits provide slip resistance while maintaining visual clarity.

Glass Thickness for Different Applications
Frameless glass treads require maximum thickness for structural integrity. GlassWalk’s treads over 1 inch thick provide necessary strength for 56-inch spans while maintaining building code safety margins.
GlassWalk maintains consistent 3-ply construction across all applications to ensure uniform performance and simplified installation. The thickness accounts for thermal expansion, wind loads, and dynamic foot traffic loading.
