Fire-Rated Glass Floors
A fire-rated glass floor is a walk-on glazed floor panel, set in a tested support frame, that keeps both its load-bearing capacity and its fire resistance for a stated time. Because a floor carries load, its classification also includes R for load-bearing capacity alongside integrity and insulation.

What should you check before ordering?
Load and fire together
A glass floor must carry its design load during the fire period. Only systems tested for both should be used.
Sizes are limited
Tested floor panels have maximum spans. Larger openings are divided by a supporting grid.
Slip resistance
Walk-on glass needs an anti-slip finish; it must be one covered by the system.
Rooflights
Horizontal glazing in a fire-rated roof or floor behaves differently from a wall, so wall glass cannot simply be laid flat.
Privacy
Obscured or patterned surfaces can be specified within the system for privacy below.
Programme
Glass floors are made to order with longer lead times; we plan early with your contractor.
What evidence do you get?
- Floor system fire test or assessment reference
- Load and span confirmation
- Support frame details
- Installer's completion record
Guide prices for fire-rated glass floors

Frequently asked questions
Can a glass floor be fire-rated?
Yes, using specialist tested systems that cover load-bearing capacity as well as integrity and insulation.
What does REI mean?
R is load-bearing capacity, E is integrity and I is insulation. A floor needs R because it carries people and loads.
How big can a fire-rated glass floor panel be?
Each system sets maximum panel sizes; larger areas are divided by a supporting grid.
Can we see through it?
Yes, with clear glass and an anti-slip finish, or obscured if privacy is needed.
