What our fire-rated glass floors service includes in County Londonderry
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.
- Anti-slip surface treatments within the system
- Horizontal fire-rated rooflights
- Steel support frames to the tested details
Before you order in County Londonderry
Slip resistance
Walk-on glass needs an anti-slip finish; it must be one covered by the system.
Sizes are limited
Tested floor panels have maximum spans. Larger openings are divided by a supporting grid.
Rooflights
Horizontal glazing in a fire-rated roof or floor behaves differently from a wall, so wall glass cannot simply be laid flat.
Which rules apply in Northern Ireland?
Northern Ireland Which rules apply?
In Northern Ireland, building work follows the Building Regulations (Northern Ireland) 2012, with fire safety guidance in Technical Booklet E, approved by the district council's building control.
Once in use, the Fire and Rescue Services (Northern Ireland) Order 2006 and the Fire Safety Regulations (Northern Ireland) 2010 require the appropriate person to maintain fire safety measures, including fire-resisting glazing.
Technical Booklet E sets its own provisions for glazing on escape routes, so designs are checked against the Northern Ireland guidance rather than English documents.
Questions from County Londonderry clients
Can we see through it?
Yes, with clear glass and an anti-slip finish, or obscured if privacy is needed.
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 you survey anywhere in County Londonderry?
Yes. We can arrange surveys anywhere in County Londonderry, including Derry / Londonderry and Coleraine.
