Fire-rated decking: Understanding fire ratings

What are fire ratings?

Fire ratings are standardised classifications that indicate how well a material can resist fire. These ratings are crucial for ensuring the safety of building occupants and minimising property damage in case of a fire.

‍

In the UK, fire ratings for building materials are primarily based on the European classification system defined in BS EN 13501-1. Here are the main fire ratings used in the

UK:

Euroclass ratings
The Euroclass system is the most important classification for external flooring and building materials. It assigns ratings based on combustibility:

• Class A1: Completely non-combustible materials
• Class A2: Materials with very limited combustibility
• Class B: Some contribution to fire spread
• Class C: Minor contribution to fire spread
• Class D: Medium contribution to fire spread
• Class E: Significant contribution to fire spread
• Class F: Easily flammable materials

‍

Specific applications

For certain applications, additional classifications are used:

‍

Roofing Materials:

• BROOF(t4): Highest performance for external fire exposure to roofs

‍

Flooring Materials:

• Suffix 'fl' is added to the Euroclass rating (e.g., A2fl)

Choosing fire-rated decking for your terrace project offers several advantages:

1. Enhanced Safety: Fire-resistant materials help slow the spread of flames, providing crucial time for evacuation in case of a fire.
2. Compliance with Regulations: Many building codes require fire-rated materials for certain applications, especially in commercial and multi-story residential buildings.
3. Durability: Fire-rated materials are often more resistant to other forms of damage as well, potentially increasing the lifespan of your terrace.
4. Peace of Mind: Knowing that your outdoor space is constructed with fire safety in mind can provide reassurance to both property owners and occupants.
