  • Cellular beams.
  • Composite deck.
  • Concrete.
  • Refurbishment or new construction.


A low density  gypsum based (with no mineral fibres), machine applied fire protection system. It is a cost effective and fast application system for the fire protection of steel and concrete structures. It bonds tightly to steel and concrete substrates, forming a hard surface which does not spall, dust or flake. Being gypsum based, is not designed for continuous exposure to weather or water.

Features and benefits:

  • Longevity- if undisturbed, Monokote is designed to last for the life of the building.
  • Proven in-place performance- it will stay in place during construction phase, for the life of the building until the day of the fire and meanwhile the intervention of the fire fighters.
  • Safety- monolithic barrier with no joints and do not need a chemical reaction.
  • Thin system- no need to allow the room between steels and over-cladding for expansions that is required for intumescent coating.
  • Low density- less net weight applied on the structures.
  • Value for money- direct application on unprimed steel with no corrosion pre-treatment in a controlled environment in a C1 (BS EN ISO 12944-2:1988).
  • Program benefit- installation to start as soon as the concrete deck of the floor above is poured.
  • Building Code compliant- ICBO, SBCCI, BOCA and ICC.
