How Cavity Barriers Stop Fire and Smoke Spread in Buildings
It’s easy to focus on visible risks like poorly maintained alarms or blocked exits when it comes to fire safety in buildings. But what about the hidden dangers? Concealed cavities in walls, floors, and ceilings can act as invisible passageways for fire and smoke, allowing them to spread rapidly and wreak havoc on properties.
For building owners, contractors, and facilities managers, ensuring these risks are addressed is about more than compliance – it’s about protecting lives, property, and peace of mind. This is where cavity fire barrier installation comes in. In this blog, we’ll take a closer look at how cavity barriers work and why they’re a game-changer in fire safety.
What are Cavity Barriers?
Cavity barriers might not be the most talked-about fire safety feature, but they’re one of the most important. Simply put, cavity barriers are fire-resistant materials installed in concealed spaces, like voids in walls, ceilings, and floors, to prevent fire and smoke from spreading.
Think about the structure of your building. Behind the surfaces you see every day are spaces that can become channels for fire if left unprotected. These hidden gaps are especially common in modern construction, where designs often include cavities for insulation, wiring, or ventilation.
By stopping fire and smoke in their tracks, cavity fire barrier services give you the confidence that your building’s hidden spaces aren’t putting lives and property at risk.
How Do Cavity Barriers Work?
Cavity barriers work by blocking or sealing concealed spaces to prevent fire and smoke from spreading. Without them, fire can travel undetected, igniting combustible materials in adjacent areas and escalating the situation.
Here at TBL Fire Protection, our passive fire protection specialists install high-quality cavity fire barriers designed to provide robust fire resistance and create a protective seal in concealed spaces.
Our fire barriers, made up of vertically hung fire barrier curtains, are fixed securely to block the passage of fire and smoke. These barriers can achieve fire ratings of up to 120 minutes, giving crucial time for evacuation and firefighting. By stopping fire at its source, cavity fire barriers significantly reduce the risk of extensive damage and ensure the safety of everyone inside the building.
What are the Key Benefits of Cavity Fire Barriers?
Prevent fire and smoke spread:
Cavity barriers are specifically designed to block fire and smoke from spreading through concealed voids, such as wall cavities, ceiling spaces, and raised floors. By sealing these hidden pathways, they contain fire within its area of origin and reduce the risk of it escalating to other parts of the building.
Protect building occupants:
In the event of a fire, cavity barriers provide crucial protection by slowing the spread of fire and toxic smoke. This extra time is essential for the safe evacuation and overall safety of occupants, especially in multi-storey or densely populated buildings.
Minimise structural and asset damage:
Uncontained fires can cause severe damage to both a building’s structure and its contents. By stopping fire from travelling through concealed spaces, cavity barriers protect adjacent areas, reducing repair costs and helping to preserve valuable assets.
Compliance with fire safety regulations:
Cavity barriers are a legal requirement in UK building regulations as part of passive fire protection systems. Properly installed cavity barriers from our accredited fire stopping company ensure your building complies with these regulations, giving you peace of mind and helping you avoid potential legal penalties.
