1. What Are Fire-Rated Doors?

Fire-rated doors are specially designed doors that resist fire for a specified period, typically 20, 45, 60, or 90 minutes. These doors are constructed with fire-resistant materials such as steel, gypsum, or treated wood and are installed to compartmentalize a building, slowing the spread of fire and smoke.

Key Features of Fire-Rated Doors:

• Fire-Resistant Core Made of materials that withstand high temperatures.

• Intumescent Seals Expand when exposed to heat, sealing gaps to block smoke.

Fire-rated doors are part of apassive fire protection system, meaning they work without human intervention. Heres how they function during a fire:

• Heat Activation:Intumescent strips around the door expand when temperatures rise, sealing gaps.

• Compartmentalization:The door acts as a barrier, preventing flames and smoke from spreading to other areas.
