When it comes to fire safety in business offices, fire doors play an essential role in preventing the spread of fire and smoke. However, the effectiveness of a fire door depends not only on its construction but also on the components that ensure its integrity during a fire. One such component is the ‘intumescent strip’. These strips are often overlooked but are crucial in maintaining fire door performance. In this post, we will explore what intumescent strips are, their importance, and why they should be a key consideration in your fire safety strategy.
What Are Intumescent Strips?
Intumescent strips are passive fire protection products designed to enhance the performance of fire doors. Made from materials that expand when exposed to heat, these strips swell to fill gaps between the fire door and its frame during a fire. This expansion helps to create a barrier that prevents fire and smoke from spreading through these gaps, thus protecting other parts of the building and providing crucial extra minutes for evacuation.
How Do Intumescent Strips Work?
Intumescent strips are typically installed around the edges of a fire door or within the door frame. Under normal conditions, they remain dormant and do not interfere with the door’s operation. However, when the temperature rises above a certain threshold (usually around 200°C), the material within the strip begins to expand. This expansion can be up to 10 times its original size, sealing off any gaps around the door effectively.
The sealing effect is vital because, during a fire, smoke and toxic gases are the primary cause of fatalities. By blocking these from entering escape routes or spreading to other areas of
Why Are Intumescent Strips Important?
- Compliance with Fire Safety Regulations
For businesses, particularly in office environments, compliance with fire safety regulations is not optional. The Regulatory Reform (Fire Safety) Order 2005 in the UK mandates that businesses must take adequate fire precautions, including the use of fire doors fitted with intumescent strips where appropriate. Failure to comply can result in legal action, fines, and, more importantly, the endangerment of lives.
- Enhancing Fire Door Performance
A fire door without an intumescent strip is like a lock without a key – it’s incomplete and ineffective. Intumescent strips ensure that fire doors perform their intended function during a fire. By sealing gaps, they maintain the door’s fire resistance, preventing the passage of fire, smoke, and heat. This is especially important in business offices, where protecting people and property is a priority.
- Cost-Effective Fire Safety Solution
Investing in intumescent strips is a cost-effective measure for enhancing fire safety. They are relatively inexpensive compared to other fire safety upgrades and offer significant protection in return. Considering the potential cost of fire damage, business interruption, and insurance claims, the investment in intumescent strips is minimal.
- Protecting Life and Property
The primary goal of any fire safety measure is to protect life and property. Intumescent strips are a key component in achieving this goal. By preventing the spread of fire and smoke, they help to ensure that evacuation routes remain clear, and that fire is contained within a specific area. This containment buys valuable time for emergency services to respond and for occupants to evacuate safely.

How to Ensure Your Fire Doors Are Properly Equipped
Ensuring that your fire doors are fitted with the appropriate intumescent strips is critical. Here are some steps to take:
