Frequently Asked Questions on Fire and Smoke Glazing
Fire and smoke glazing is a critical part of modern building safety, providing protection, visibility, and compartmentation during emergencies. At OAG, we design and install fully compliant fire and smoke glazing systems that meet strict regulatory requirements while supporting architectural design intent. Below are frequently asked questions about fire-rated glass and how it’s used.
Fire-rated glass is classified by its level of protection:
- Integrity only (E-rated): Resists fire and prevents flames or hot gases from passing through
- Integrity and insulation (EI-rated): Also blocks heat transfer for a specified period
- Radiation control (EW-rated): Limits thermal radiation while maintaining integrity
OAG specifies the right fire-rated glass type based on location, use, and regulatory needs.
Fire-rated glass is available in 30, 60, 90, or 120-minute configurations. The duration indicates how long the glass can withstand fire under test conditions. The required rating depends on the building’s use, fire strategy, and the specific compartmentation requirements.
Typical applications include:
- Stairwells and lift lobbies
- Corridor and escape route partitions
- Fire doors and vision panels
- Smoke containment areas
- Atriums and mezzanines
OAG works closely with fire engineers and architects to integrate fire and smoke glazing into safety strategies and layouts.
Yes — with the right system and certification. Fire-rated glazing can now be used in large formats, curved glass, and even frameless systems, using approved fixings and intumescent seals. At OAG, we install tested systems from trusted manufacturers to ensure performance without compromising on design.
While fire-resistant glazing contains flames and heat, smoke control systems focus on preventing the movement of smoke through a building. Smoke barriers and smoke-tight doors are often used alongside fire-rated glass to maintain tenable conditions for safe evacuation. OAG provides systems that meet both fire and smoke containment standards.
Fire and smoke glazing must comply with:
- Approved Document B (Fire Safety) of the Building Regulations
- BS EN 1364 & 1634 fire resistance testing standards
- BS 9999 and BS 9991 fire strategy guidance
- Fire certification and CE marking for all components
- Intumescent seals and hardware that support the glass performance
OAG ensures every fire glazing installation is fully certified and traceable.
Yes. Many fire-rated glazing systems now include acoustic insulation and thermal performance layers. Glass can be double-glazed, laminated, or coated with low-emissivity layers while still maintaining fire protection. This makes fire and smoke glazing suitable for modern offices, schools, and healthcare buildings.
Absolutely. Fire-rated glass has evolved significantly and now supports frameless options, large spans, and minimal sightlines. It can be clear, tinted, frosted, or printed, allowing it to blend into high-end designs while delivering critical safety performance.
OAG combines technical expertise with practical delivery to provide fire and smoke glazing systems that meet safety standards without compromising design. We work with leading suppliers, architects, and consultants to ensure compliance, certification, and visual quality — from specification to final installation.
