Intumescent Coatings

New Image Contracts Ltd specialise in passive fire protection, all employees have attended training courses and gained certification for the application and knowledge of intumescent coatings.

Why Is Fire Protection Required?

The fundamental purpose of passive fire protection systems is to first and foremost allow for the safe escape of the building occupants and to also reduce the risk of collapse for the emergency services to be able to carry out their work. Secondly to prevent / reduce the amount of damage to the building structure and neighbouring structures.

Other more commercial reasons for the use of fire protection systems, is to reduce the amount of damage and prevent collapse of the building. This intern can help to:

  • Reduce the possible risk to the fire fighters.

  • Reduce the rising cost of insurance polices.

  • Protect capital investment.

Protection of structural steelwork

During a fire situation the temperature within a building can rise from ambient around 20°C, up to 1000°C. As the temperature in the building increases, so does the temperature of the steel structure that supports the building. All steel sections have whats know as a critical steel temperature. This is the temperature at which the steel section begins to loose its strength and buckle.

The building regulations require that structural steel is protected against fire, to ensure that the load-bearing strength of the steel is not decreased as the temperature increases.

Determining the right intumescent for the project

The specific intumescent paint for each project normally comes down to the following factors:

  • Fire performance required, 30, 60, 90, or 120 minutes.

  • Type of steel member to be protected.

  • The design and aesthetic requirements.

  • Environmental conditions & programme.

  • Cost considerations.

  • Steel location, Internal or External
