Why Size And Thickness Matter

Many buyers only focus on fire rating, but actual project performance also depends on panel size and thickness.

  • Oversized panels may require thicker glass

  • Large openings may need stronger frames

  • Transportation limitations may affect panel size

  • Installation access may restrict large panels

Large glass panels may look better, but they must still meet structural and fire performance requirements.

Common Fire Rated Glass Thickness Options

Different fire ratings often require different glass thickness ranges:

  • EI30: typically thinner structures

  • EI60: medium thickness solutions

  • EI90: thicker multi-layer systems

  • EI120: heavy-duty fire protection systems

Actual thickness varies depending on manufacturer systems and project certification requirements.

Maximum Glass Size Considerations

Before ordering oversized panels, buyers should confirm:

  • Maximum certified panel size

  • Glass weight

  • Shipping restrictions

  • Site lifting limitations

  • Installation path access

Very large panels may require project-specific engineering review.

Steel vs Aluminum Frame Selection

Frame selection directly affects fire system stability.

  • Steel frames: stronger support for large/heavy panels

  • Aluminum frames: cleaner appearance for certain projects

  • Custom frames: special architectural designs

Frame compatibility must match tested fire systems.
