Abstract
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° C. for at least 10 minutes prior to failure.
Claims27
An intumescent mesh, comprising:
- a mesh structure woven from strands, the strands defining openings in the mesh structure, the strands being non-metal;
- an intumescent material 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;
- wherein the intumescent mesh is able to withstand a temperature of at least 980° C. for at least 10 minutes prior to failure.
A method of protecting a surface against fire or heat, comprising the steps of:
- providing an intumescent mesh comprising an intumescent material applied to a mesh structure, the mesh structure being woven from strands that define openings in the mesh structure, the strands being non-metal, 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 material being activated upon application of an activation temperature, the intumescent mesh is able to withstand a temperature of at least 980° C. for at least 10 minutes prior to failure;
- and
- installing the intumescent material immediately adjacent to the surface to be protected.
