European Reaction to Fire classification system (Euroclasses)

Key Points

• System for comparing construction products for ignitability, flame spread, heat release, smoke production and propensity for producing flaming droplets/particles etc.
• Accepted by all European Union States but not mandatory or applied in the UK
• Products achieving A1 classification, under the Euroclass system, are defined as non-combustible in UK Regulations.

Fire Safety Legislation

The implementation of a single classification system across the EU member states has introduced a common method for comparing the reaction to fire performance of construction products.

Testing is standardised through the use of BS EN 13501-1 ‘Fire classification of construction products and building elements’.

For insulation products intended to be used in wall and ceiling constructions, there are seven reaction to fire classification levels available A1, A2, B, C, D, E and F., additional classifications provide information on a product’s tendency to produce smoke and flaming droplets or particles.

Rockwool stone wool insulation is classified as A1 which is the highest ranking of the reaction to fire classifications. Non-combustible in nature, Rockwool can withstand temperatures in excess of 1000°C without melting.
