passive Fire Protection

Passive fire protection works by protecting against flame, heat and smoke to maintain the fundamental requirements of building compartmentation, structural stability, fire separation and safe means of escape.

Primary passive fire protection measures achieve their intended purpose by raising the fire resistance of the structure to a specific level, minimising the danger of fire-induced collapse or structural distortion.

Intumescent Paint

Intumescent paint is a thin film coating applied to structural steel members to protect against fire. When activated by the heat of a fire the intumescent coating expands, generating a foam-like char that insulates the metal from the external heat, maintaining the structural integrity of the steel member.

Most intumescent coatings are applied by spray, creating a quick, cost-effective method of achieving up to two hours of fire protection on structural steelwork.

The thickness of the paint required is determined by the Hp/A value of the steel section and our experienced team can advise on the requirements for your structure to achieve the required protection rating.

Many structures benefit from a combination of both intumescent paint to the structure and firestopping mechanisms to the internal compartments, as well as acoustic and air seals.

Intumescent paint can be challenging to apply and the use of an accredited specialist with trained installers is highly recommended. Led by experienced installer and Contracts Manager (Paint), Jason Loughran the Pyrotect team will assess the situation to ensure that the application is completed under the correct conditions to achieve the required fire rating.
