Abrégé

An intumescent mesh comprises a mesh structure woven from strands that define openings in the mesh structure, the strands being made from non-metal materials. An intumescent material is applied to the strands, the intumescent material being carried such that, in an inactivated state the intumescent material permits airflow through the openings in the mesh structure, and in an activated state, the intumescent material swells and restricts airflow through the openings in the mesh structure. The intumescent mesh is able to withstand a temperature of at least 980℃ for at least 10 minutes prior to failure.
