Construction products reaction to fire

By construction products’ reaction to fire we mean the contribution of the construction product to a fire in the room where the fire occurs. After the European classification system, the construction products’ and building components’ (not including floor coverings and roof coverings) reaction to fire can be divided into the following main categories:

  • A1 construction products that do not contribute to fire
  • A2 construction products whose contribution to the fire is extremely limited
  • B construction products whose contribution to fire can be accepted
  • C construction products, which to a limited extent contribute to the fire
  • D construction products, whose contribution to the fire can be accepted
  • E construction products, which contribute to a relatively large extent to the fire
  • F means that it is not documented whether or not the product meets the classification requirements
