In this blog, we will explore the differences, benefits, applications, and key considerations when choosing between these two types of fire-rated doors.

1. Understanding Fire Rated Doors

Fire-rated doors are specially designed to withstand fire for a specified duration (typically 30, 60, 90, or 120 minutes). They are tested and certified to meet international standards such asUL (Underwriters Laboratories), BS (British Standards), or NFPA (National Fire Protection Association).

Key Features of Fire Rated Doors:

• Fire Resistance:Withstand high temperatures and prevent fire spread.

• Smoke Control:Seal gaps to restrict smoke passage.

• Structural Integrity:Maintain stability during a fire.

• Certification:Must comply with local fire safety regulations.

2. What is a Slab Fire Rated Door?

ASlab Fire Rated Doorrefers to the door leaf (the flat panel) without the frame, hinges, or hardware. These doors are designed to be installed into existing or custom frames and are often used in retrofitting projects.

1. What Are Fire-Rated Doors?

Fire-rated doors are specially constructed doors designed to withstand fire for a specified duration, typically ranging from20 minutes to 180 minutes(FD20, FD30, FD60, FD90, FD120, FD180). They are a critical part ofpassive fire protection systems, helping to compartmentalize fire and smoke within a building.

Key Features of Fire-Rated Doors:

• Fire Resistance:Made from materials that resist combustion.

• Smoke Seals:Prevent smoke from spreading.

• Intumescent Strips:Expand under heat to seal gaps.

• Certification:Must comply with international standards likeBS 476, EN 1634, UL 10C, or NFPA 80.

2. Understanding Slab Fire Rated Doors

ASlab Fire Rated Doorrefers to the door leaf (the flat, solid part) without the frame or hardware. These doors are supplied as standalone panels that can be fitted into compatible fire-rated frames.

Characteristics of Slab Fire Rated Doors:
