Reaction to Fire — Understanding Product Classification NewSupplier CPD

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

About this CPD Resource

How to interpret reaction to fire test results and classification reports for insulation and construction products, and how these relate to Approved Document B compliance.

The European reaction to fire classification system (Euroclass) can be confusing for those not regularly working with fire test standards. Understanding what Euroclass ratings mean, how products achieve them, and how they relate to the requirements of Approved Document B is an important competency for architects and specifiers working on buildings where combustibility of construction materials is a regulatory consideration.

Learning Outcomes

  • Understand the European reaction to fire classification system (Euroclass)
  • Interpret test reports and certificates for construction products
  • Apply Approved Document B requirements for insulation products
  • Distinguish between reaction to fire and fire resistance performance

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 Knauf Insulation Limited 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 Knauf Insulation Limited 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 does A1 non-combustible classification mean?
A1 is the highest Euroclass reaction to fire rating, indicating that a product does not contribute to fire in any stage, including fully developed fires.
Are there limitations on combustible insulation in high-rise buildings?
Yes. The Building (Amendment) Regulations 2018 prohibit the use of combustible materials in the external walls of residential buildings over 18 metres in England.
What is the difference between reaction to fire and fire resistance?
Reaction to fire measures how a product contributes to a fire. Fire resistance measures how long a construction element can prevent the spread of fire and maintain structural integrity under fire conditions.
