Internal fire door sets play a critical role in ensuring the safety of building occupants by limiting the spread of fire and smoke. Designed to compartmentalise fires and protect escape routes, these doors are essential in both residential and commercial settings. But what exactly makes them effective, and how do they work?

In this guide, we’ll explore everything you need to know about internal fire doors, including their construction, fire resistance ratings, and maintenance requirements.

Key Takeaways

• Purpose: Internal fire door sets slow fire and smoke spread, protecting lives and property.
• Construction: Made from solid-core materials like engineered timber or steel, combined with intumescent strips.
• Fire Resistance Ratings: Typically FD30 (30 minutes) or FD60 (60 minutes).
• Compliance: Must meet UK safety standards such as BS 476 or EN 1634.
• Maintenance: Regular checks ensure optimal performance in emergencies.

Understanding the Purpose of Internal Fire Doors

Fire doors serve as vital barriers during a fire emergency. They compartmentalise fire, preventing it from spreading to other parts of a building. This containment gives occupants time to evacuate safely while keeping escape routes clear of smoke and flames.

Benefits of Fire Doors

1. Protecting Lives: Safeguards hallways and stairwells to ensure safe exits.
2. Minimising Damage: Prevents fire from spreading, reducing structural harm.
3. Supporting Emergency Services: Provides firefighters time to control the situation.

What is an Internal Fire Door Made Of?

What internal fire doors are made of can vary, as various materials and construction methods can be used. Fire doors are typically built using solid-core materials, which resist high temperatures and prevent warping during a fire.

Materials Used in Gerda Security Products Fire Doorsets:

• Engineered Timber: Found in our Safer Homes Range, engineered timber combines durability with aesthetic appeal.
• Insulated Steel: Featured in our Contemporary Range, steel adds strength and thermal resistance.

Additionally, these doors are equipped with intumescent strips. When exposed to heat, the strips expand to seal gaps between the door and its frame, blocking smoke and flames.

Fire Resistance Ratings Explained

Fire resistance ratings are crucial in determining how long a fire door can withstand flames and smoke. These ratings, such as FD30 and FD60, provide clarity on the door’s performance.

What Do the Ratings Mean?

• FD30: Withstands fire for 30 minutes, suitable for most residential settings.
• FD60: Provides 60 minutes of protection, ideal for commercial or high-risk areas.

These ratings are achieved through rigorous testing to ensure the door meets standards like BS 476. The higher the rating, the more effective the door is at protecting escape routes.
