Cavity Barriers

What is the importance of a Damper?

When constructing a building with voids and cavities, it’s crucial to incorporate cavity barriers to effectively halt the unseen spread of fire within concealed cavities. These barriers are typically constructed from a non-combustible material such as Stone Mineral Wool with a metallic foil outer coating.


In the case of rainscreen façade systems where an air gap needs to be maintained within the system to prevent a build-up of damp, full-fill cavity barriers may not be used at horizontal compartment lines. At these points an open-state cavity barrier may be installed. These cavity barriers will also typically be a non-combustible mineral wool, but fitted with an intumescent facing material designed to expand upon exposure to heat or flames, effectively sealing off the cavity. This ensures that fire and smoke cannot permeate between different compartments within the structure. Cavity barriers play a pivotal role in enhancing fire safety measures, safeguarding both property and lives.

What are Cavity Barriers

Cavity barriers are essential components in building construction used to prevent the spread of fire and smoke within a structure. They are typically made from stone mineral wool and may also include intumescent materials that expand when exposed to heat or fire. These barriers are strategically installed within voids and cavities of a building to effectively seal off these spaces, thereby inhibiting the movement of flames and smoke between different compartments. By containing the fire within its origin area, cavity barriers help to minimise damage caused by the uncontrolled spread of fire and increase the overall fire safety of the building.

Cavity Barrier Installation and Fire Barrier Building Regulations

Ensuring compliance with the compartmentation requirements of the building regulations is paramount in any construction project. Cavity barrier installation plays a crucial role in meeting these stringent standards, as they effectively prevent the spread of fire and smoke within a building’s voids and cavities. By utilizing high-quality cavity barriers made from appropriate materials, construction professionals can guarantee optimal fire safety measures. Adhering to these regulations not only enhances the safety of occupants, but also protects property and minimizes potential damage in the event of a fire. Trustworthy installation practices and adherence to fire barrier building regulations are essential for creating a secure and resilient built environment.

Fire barriers in cavity walls

Fire barriers in cavity walls are indispensable elements for ensuring compliance with stringent building regulations and bolstering fire safety in construction projects. These barriers serve as critical components that effectively prevent the spread of fire and smoke within the cavities of a building’s walls. By incorporating reliable fire barriers into cavity wall systems, construction professionals can mitigate the risk of fire propagation between different compartments of the structure. Utilising high-quality fire barrier materials and adhering to installation guidelines are essential steps in meeting regulatory standards and safeguarding both occupants and property. Proactive measures such as proper, documented fire barrier installation contribute significantly to creating a secure and resilient built environment that prioritizes the safety of all stakeholders.

Fire Stopping

Pipe closures are designed to preserve the integrity of a fire-resistant compartment where pipes pass through floors or walls.

Fire Stopping

Fire dampers are crucial for creating barriers that resist the spread of fire and smoke through ductwork systems.

Fire Stopping

Upon detecting a fire, the fire curtain rapidly deploys, forming a barrier that divides large spaces into smaller compartments.
