Types of Passive Fire Protection

 

What happens to intumescent paint in a fire?

Intumescent paint is designed to expand and create a protective char layer when exposed to heat or flames. When a fire occurs, the heat causes the intumescent paint to react, expanding and forming a foam-like layer that insulates the underlying structure. This expanded layer acts as a barrier, slowing down the transfer of heat to the protected surface, thus providing fire resistance and protection. Is there anything else you would like to know about intumescent paint?

HPE mastic

High pressure exerting intumescent mastic is a type of fireproofing material that expands when exposed to high temperatures. It is used to seal gaps and joints in buildings to prevent the spread of fire and smoke. The mastic is applied in a compressed state and expands significantly when heated, forming a high-density barrier. This expansion helps to fill gaps and protect against fire, providing additional time for occupants to evacuate the building and for firefighters to control the blaze. Is there anything specific you would like to know about high pressure exerting intumescent mastic?
