The Importance of Fire Seals with a Fire Door

27/08/2025

Fire seals are an integral element in the fabric of fire doors. Their importance cannot be overstated, as they can make the difference between life and death in the situation of a devastating fire. In fact, their importance is being highlighted this week as part of Fire Door Safety Week. This is the British Woodworking Federation’s campaign to raise awareness of the need for fire doors and break down exactly why they are so essential.

In this blog, we’ll explore the significance of fire seals, taking a look at why Noberne’s seals offer the best protection in the industry. They are one small component in what makes fire doors so essential in safety for commercial businesses. Fire Door Safety Week highlights this importance, which we will also explain.

What Are Fire Seals?

Fire seals, often referred to as intumescent seals or fire door seals, are an integral component of fire doors and frames. These seals are designed to expand and seal gaps around the perimeter of a fire door when exposed to high temperatures, typically during a fire.

Their primary purpose is to prevent the passage of smoke, flames, and hot gases from one area of a building to another. This containment of fire and smoke is crucial for the safety of occupants and the protection of property.

What Do Fire Seals Do?

Fire doors are specially designed doors that are capable of withstanding fire for a specified period, allowing for the safe evacuation of people and preventing the spread of fire within a building.

They are a critical part of a building’s passive fire protection system. When combined with properly installed fire seals, fire doors become highly effective at compartmentalising fire and smoke.

Here are five reasons why fire seals are so important with fire doors:

1. Life Safety

The primary goal of any fire safety measure is to save lives. Fire seals play a pivotal role in ensuring the safety of building occupants during a fire. By preventing the spread of smoke and fire, they buy valuable time for people to evacuate safely and for firefighters to contain the blaze.

Fire doors without properly functioning seals can fail to perform their intended purpose, putting lives at risk.

2. Property Protection

Fires pose a threat not only to human life but also to property and assets. Fire seals help contain the fire within a specific area, limiting the damage caused by smoke and flames.

This containment can be the difference between a minor incident and a catastrophic loss.

3. Legal Compliance

Building codes and regulations require the installation of fire doors and their associated seals in various types of buildings, depending on their use and occupancy. Failing to comply with these regulations can result in serious legal consequences.

Noberne understands the importance of adhering to these standards and can provide compliant products to meet specific requirements.

4. Peace of Mind

Knowing that your building is equipped with high-quality fire doors and seals provides peace of mind to building owners, managers, and occupants.

It ensures that, in the event of a fire, the safety measures in place are reliable and effective.

5. Cost Savings

While investing in fire doors and seals may seem like an added expense, it’s important to consider the potential cost savings in the long run.

Preventing a fire from spreading can significantly reduce the damage to a building, minimising repair and reconstruction costs.

What Are the Different Types of Fire Seals?

Noberne has an extensive range of fire seals, all serving different purposes for different situations.

Here is a list of our product range:

  • Intumescent Seals – Installed around the edges of fire doors or in the door frame. When exposed to heat during a fire, the intumescent material in the strip swells or expands, sealing the gap and preventing the passage of smoke and flames.
  • Fire and Smoke Seals – Designed for use with fire-rated glass windows and doors. They help maintain the fire rating of the glazed opening by preventing the spread of fire and smoke through gaps around the glass.
  • Fire Only Seals – Designed to provide fire resistance in specific applications. These seals expand when exposed to high temperatures, creating a barrier that helps contain the fire within a designated area.
  • Fire Rated Foam – Used to fill gaps, joints, or penetrations in building structures, such as walls and floors, to prevent the spread of fire, smoke, and hot gases.
  • Sealants & Mastic – Fire-resistant materials used to seal gaps, joints, and penetrations in building structures to prevent the spread of fire, smoke, and hot gases. They are commonly applied in areas such as walls, floors, and around fire-rated doors, providing a fire-resistant barrier.
  • Air Transfer Grilles – Designed to maintain a balance between temperature and pressure in various spaces while restricting the passage of fire and smoke.
  • Glazing Seals – Designed to maintain the fire rating of these openings by preventing the spread of fire, smoke, and hot gases through gaps around the glass.
  • Pipe Collars & Wraps – Used to seal penetrations created by pipes and cables passing through fire-rated walls or floors in buildings.
  • Fire Door Hardware – Components and accessories used in conjunction with fire doors to ensure their proper functioning and compliance with fire safety standards.
  • Fire Rated Letter Plates – Designed mail slots or openings in fire-rated doors that comply with fire safety regulations.
