The European Reaction to Fire classification system

Given that building fires can quickly spread through the material of an external cladding system or through the cavities, careful consideration of the design and potential fire risk is required.  Particular emphasis should be put on containment to allow safe evacuation, reduce the risk of fire spread to other buildings and to enable access for fire fighters.

The European Reaction to Fire classification system (Euroclasses) is the EU common standard for assessing the qualities of building materials in the event of a fire. This information is relevant for the United Kingdom and the Republic of Ireland.

Euroclasses arise from classification systems for ‘reaction to fire’ performance of construction products. It provides a common method for comparing the performance of products in fire.

The Euroclass system:

  • Compares ignitability, flame spread, heat release, smoke production and propensity for producing flaming droplets/particles etc.
  • Is accepted by all European Union States (mandatory where there is a Harmonised Product Standard)
  • Includes seven classification levels, from A1 to F
  • States that products achieving A1 classification are defined as non-combustible under Regulations

Non-combustible stone wool

ROCKWOOL is made from naturally fire resistant stone wool.  Created using the same processes that occur at the heart of a volcano, the material can tolerate temperatures of up to 1000°C and has been awarded this highest possible European classification: A1 non-combustible.  It provides vital fire protection in buildings, keeping people safe, as well as minimising damage to valuable assets. In the event of a fire, it is designed to remain stable, slow the spread of flames and help protect the building’s load-bearing structure, buying valuable time for occupants to safely escape to protect lives and investment.

Put simply, rock won’t burn.

The ROCKWOOL Stone Wool product range focusses on:

  • Walls
  • Floors and ceilings
  • Roofs
  • HVAC
  • Fire Protection

ROCKWOOL stone wool tolerates temperatures of up to 1000°C
