How to Identify if Glass is Fire Rated?
Understanding the nuances of fire-rated glass is crucial, not just for compliance, but also for ensuring safety in both domestic and commercial settings. In this article, the Bridgewater Glass team (with over 75 years’ experience in the bespoke glass game) explains everything you need to know about fire-rated glass, including what it is and how to identify it.
What is Fire Resistant Glass?
Fire-resistant glass plays a pivotal role in preventing the spread of fire and smoke. It’s a safety essential, designed to withstand extreme heat and maintain integrity over a specified period. These glasses serve as a barrier, offering vital time for evacuation and emergency response.
How to Tell if Glass is Fire Rated in the UK
Identifying fire rated glass involves understanding the 3 Cs: composition, classification and certification. Here are the key aspects to consider:
Understanding the Marks and Certification
Every piece of genuine fire-rated glass carries specific marks and certifications. For instance, genuine Pyroguard Fire Glass is typically marked with the brand name, the standard (like EN14449), and the impact rating (e.g. 2B2). Additionally, a genuine Pyroguard stamp indicates certification for specific fire-rated applications.
Types of Fire Resistant Glazing
Various technologies underpin fire-resistant glazing. These include wired, ceramic, heat-soaked modified thermally toughened, resin-laminated and more. Each type has unique characteristics that contribute to its fire-resisting capabilities.
Classifications of Fire Resistance
UK Building Regulations classify fire resistance in terms of integrity and insulation. Integrity refers to the glass’ ability to prevent flames and hot gases from passing through, while insulation additionally limits heat transfer.
Installation and Compliance
A crucial aspect of fire rated glass is its installation. The entire fire-resistant glazed system, including seals, beads, frames and the glass itself, must be compatible and installed as assessed by a competent authority. The glass must be tested and classified for its specific application, whether as a screen, door, roof or facade.
On-site Verification
Once on-site, verifying the fire-resistant performance includes checking for official evidence from a competent authority, evidence of installer competence, a permanent stamp on the glass indicating the product name, manufacturer and, ideally, the fire performance rating. It’s also essential to ensure proper storage and handling of the glass types and adherence to health and safety guidelines during installation.
