Product Description

Fire Rated Door

fire rated door is a critical safety component in building design, specifically engineered to compartmentalize fire and smoke for a defined period. Its primary function is to slow the spread of flames and hot gases, creating protected escape routes for occupants and allowing time for emergency services to respond.

These doors operate on two key principles: integrity and insulation. Integrity means the door assembly, including the door leaf, frame, seals, and hardware, remains intact without developing gaps or holes. Insulation ensures the unexposed side does not reach critically high temperatures. This is achieved through specialized construction. The core is typically filled with non-combustible materials like mineral wool, while intumescent seals around the edges expand dramatically when heated, sealing off deadly smoke and gases.

Critical components include a self-closing mechanism, usually via a coordinated door closer, and positive latching to ensure the door stays fully closed. All hardware must be listed for use with the specific door assembly. Fire doors are rigorously tested in accordance with standards (e.g., UL, BS, EN) and are given a rating in minutes, such as 20, 60, 90, or 180, indicating their proven resistance duration.

Their application is mandated by building codes in stairwells, corridors separating different occupancy areas, mechanical rooms, and other high-risk locations. It is crucial that fire doors are never propped open, as this completely negates their life-saving function. Proper installation, regular inspection, and maintenance are essential to ensure they perform as designed in an emergency.

Fire doors have three main functions:

1. When the fire is in the initial stage, the tightness and proper installation of the fire door can control the supply of oxygen in the room. Effectively, the fire control is in the initial stage.

2. When the fire reaches a certain stage, the tightness of the fire door prevents the spread of fire and smoke, allowing the escaper to have more time to escape.

3. When people escape, fire doors can ensure that people pass safely through the escape route.
