Choose the Right Type of Structural Glass

Not all glass products are suitable for flooring applications.

Structural flooring typically uses:

• Fully tempered safety glass
• Laminated glass with multiple interlayers
• Heat-strengthened glass where required
• Multi-layer structural glass assemblies

Laminated construction is particularly important because the interlayer keeps the panel intact even if one layer becomes damaged, improving occupant safety.

Consider Panel Size and Layout

Panel dimensions significantly influence both appearance and structural performance.

Architects should evaluate:

• Joint locations
• Support spacing
• Walking patterns
• Expansion allowances
• Visual symmetry

Larger panels create a cleaner appearance but may require additional structural engineering.

Frame and Support Systems

The supporting framework is just as important as the glass itself.

Typical framing systems include:
