Common Reasons For Site Inspection Failures

Fire rated glass projects often fail inspection due to incomplete documentation, mismatched panels and frames, improper installation, missing fireproof seals, incorrect hardware, and non-compliance with local fire codes.

1. Incorrect Fire Rating Or Panel Type

Using panels with the wrong EI rating, thickness, or laminated structure can result in non-compliance. Buyers and contractors must verify the fire rating matches the project requirement before installation.

2. Mismatched Frame System

Fire rated glass must fit properly into the intended frame profile. Using the wrong frame, missing glazing beads, or incorrect seal dimensions can compromise performance and cause inspection failure.

3. Missing Or Improper Hardware

Door closers, hinges, locks, handles, panic bars, and access control must be compatible with the fire rated glass door. Missing or incompatible hardware is a frequent cause of failed inspections.

4. Improper Installation Or Alignment

Panels must be level, edges properly sealed, and doors aligned with the frame. Poor site handling, incorrect lifting, or uneven floor/wall surfaces can lead to gaps, leaks, and project rejection.

5. Documentation And Drawing Issues

Incomplete RFQs, missing drawings, or incorrect door schedules can cause discrepancies between what is ordered and what is installed. Suppliers and contractors should verify all documents before production.

Inspection Failure Prevention Checklist

  • Verify fire rating and glass type (EI30/EI60/EI90/EI120)

  • Confirm panel size, thickness, and layout

  • Match frame type, glazing beads, and seals

  • Check door hardware compatibility

  • Verify installation conditions and site measurements

  • Review RFQ, drawings, and door schedules

  • Confirm packaging, transport, and handling procedures

  • Ensure compliance with local fire codes

  • Coordinate installation team communication

  • Double-check oversized or irregular panels

Fire rated glass project inspection failures are mostly preventable. By confirming fire rating, panel type, frame system, hardware, site conditions, and documentation, contractors can reduce rework, avoid rejection, and ensure smooth project delivery.
