5 Things You Need To Know About Fire Doors (Part 2)


Every individual has encountered at least one fire door in the course of their daily existence. Whether in a shopping mall, workplace, place of employment, or an airport. However, to what extent do we truly understand fire doors? Why do they contribute so significantly to life-saving efforts during fire emergencies?


What Enhances the Fire-stopping Potential of a Fire Door?

By employing a close-mechanism design principle, every fire door is equipped with a hydraulic mechanism or a spring load positioned at the top. In the event of a fire-related incident, this mechanism activates and effectively closes the door. The frame is flush with these specialised doors. Additionally, at the base of each door is an intumescent strip that expands when exposed to heat and is packed with a fire-resistant sealant to increase the fire resistance potential of the doors.


Are All Doors with Some Fire-stopping Attributes Considered to Be Fire Doors?

Put simply, no! In order to obtain certification as a fire door, a manufacturer is required to verify the safety of the door design and grant certification subsequent to conducting extensive testing, including stress simulation and fire testing.


But, How Long Does a Fire Door Protect You?

Each fire door is classified by a unique classification. Every grade imparts a distinct layer of defense that offers resistance for an interval ranging from a minimum of 30 minutes to a maximum of 120 minutes.



We specialise in the protection of buildings from fire by the insulation of structural members, walls and tanks against direct attack from flames by maintaining load-bearing members and tank-shells below the critical point at which failure or weakening is likely to occur.
