How Intumescent Painting Works
Intumescent coatings are designed to expand when exposed to high levels of heat. This expansion retards the transfer of heat, giving up to four hours protection during a fire and greatly reducing the immediate impact of fire spread and heat damage.
In structural steel this retardant quality helps to maintain the building's load bearing abilities so preventing short term collapse or distortion.
Different applied thickness of intumescent coating will give varying thicknesses of ‘char’, and therefore differing time periods of fire resistance. The amount of applied intumescent required to give the specified period (usually 30, 60, 90 or 120 minutes) is usually referred to as the ‘loading’ needed.
For example, to protect a certain size steel section for 30 minutes might require a loading of 350 microns dry film thickness (dft) of intumescent. We calculate the loadings and the required thicknesses of intumescent paint required, per individual steel section, for the timings required.

WHAT IS FIRE PROTECTION
A building fire protection comes in two specific forms, active and passive systems:
- Active systems in the form of, suppression, extinguishers, sprinkler, alarm and extract ventilation.
- Passive systems as fire rated doors, barrier, ceilings and structural fire protection.
The overall aim of active systems are to extinguish the fire by:
- Detecting the fire early and evacuating the building
- Alerting emergency services at an early stage of the fire
- Control the movement of smoke and fire
- Suppress and/or starve the fire of oxygen and fuel
The overall aim of passive systems are to contain the fire by:
- Use of fire rated partitions and doors to prevent the fire and smoke from moving from one compartment to another
- Delaying the collapse of the building structure
- Delaying the growth of the fire
In structural steel this retardant quality helps to maintain the building's load bearing abilities so preventing short term collapse or distortion.
