Fire-Rated Glazing — Classification, Testing and Specification NewSupplier CPD

Fire Safety 🏭 Pilkington ⏱ 1 CPD Hour Free 📅 Added May 2026

About this CPD Resource

How fire-rated glass works, the European classification system for fire-resistant glazing, application requirements and how to specify compliant fire-rated glazing solutions.

Fire-rated glazing is increasingly used in modern buildings to provide compartmentation while maintaining visual connectivity between spaces. Specifying fire-rated glazing correctly requires a thorough understanding of the European classification system, the interaction between glass performance and framing requirements, and the installation standards that determine whether the system achieves its rated performance.

Learning Outcomes

  • Understand fire-resistant glass classification (EI, EW, E ratings)
  • Apply fire-rated glazing requirements from Approved Document B
  • Specify appropriate fire-rated glass products for different applications
  • Understand the framing and installation requirements for fire-rated glazing systems

Why This CPD Matters

Fire safety has become one of the most scrutinised areas of construction specification and professional practice following the Grenfell Tower fire of 2017. The subsequent Hackitt Review, the Building Safety Act 2022, the Building (Amendment) Regulations 2018 and the ongoing work of the Building Safety Regulator have fundamentally changed the regulatory landscape for buildings — particularly higher-risk residential buildings of 18 metres or more. For construction professionals, keeping pace with these changes is not just a matter of good practice; it is a professional competency requirement.

The Fire Safety Act 2021 and Building Safety Act 2022 have introduced new roles and responsibilities — including the Principal Designer and Principal Contractor under the Building Safety Regulations — that require demonstrable competency in fire safety. This CPD from Pilkington United Kingdom Limited (NSG Group) contributes directly to that competency development, covering aspects of fire safety that are directly relevant to specification, design and construction practice in the current regulatory environment.

Key Topics and Industry Context

Fire safety in buildings encompasses a wide range of technical and regulatory considerations. Passive fire protection — the use of construction materials and systems to contain fire and prevent its spread — is fundamental to building design and requires understanding of fire resistance ratings, compartmentation principles and the performance of specific construction products under fire conditions. Active fire protection systems including sprinklers, smoke detection and alarm systems require coordination between architectural, structural and building services design. The external wall and facade system is now one of the most closely scrutinised elements of any building following Grenfell.

This resource from Pilkington United Kingdom Limited (NSG Group) provides structured learning on fire safety topics that are directly applicable to construction practice. Professionals working on higher-risk buildings — defined under the Building Safety Act as residential buildings of 18 metres or more — have particular need for up-to-date fire safety knowledge, and this CPD contributes to the competency evidence that the Building Safety Regulator may require.

How This Fits Your CPD Requirements

Fire safety CPD is relevant across multiple professional bodies. RIBA includes fire safety within its mandatory core curriculum, meaning RIBA Chartered Members must engage with this topic as part of their 35 hours of annual CPD. RICS members working in building surveying, project management or development consultancy need fire safety knowledge to advise clients effectively on compliance. CIOB members managing construction projects on higher-risk buildings need to understand the fire safety requirements that affect their programme and specification. ICE members involved in structural or civil engineering on residential buildings need awareness of the interface between structural design and fire safety requirements.

What do E, EW and EI fire ratings mean?
E (integrity) rated glass prevents flames and hot gases passing for the rated period. EW additionally limits heat radiation to 15 kW/m2. EI limits heat transmission so the unexposed face temperature rise is limited to 140 degrees C average.
What glass types achieve EI ratings?
EI-rated glass is typically a laminated product with intumescent interlayers that expand on heating, or a specially formulated glass-ceramic product.
What framing requirements apply?
The fire performance of a glazing system depends on both glass and frame. Fire-rated glazing must be installed in frames tested as part of the certified system.
