Intumescent Spraying / Passive Fire Protection
Intumescent painting of steels is now a legal requirement for commercial and public buildings. The application of a film of Intumescent paint to steel increases its burn time by insulating it and increasing the structural integrity of a building under the extreme temperatures of a fire.
An intumescent paint works by reacting to heat and swelling in a controlled manner to many times its original thickness, producing a carbonaceous char formed by a large number of small bubbles that act as an insulating layer to protect the substrate. It also provides a higher level of fire retardancy to the surfaces it is sprayed on.
