Caswell UK are specialists in fire resisting ductwork for commercial and industrial buildings. Fire resisting ductwork supports protected ventilation routes while helping to reduce fire movement between compartments.

Ventilation systems are designed to move air between internal spaces. During a fire, these same routes may create a pathway for flame spread if they are not protected. Fire resisting ductwork helps prevent this by protecting airflow routes from collapse.

We think that relying on trained fire safety installers can help ensure that ventilation systems support safe evacuation procedures.

Fire resisting ductwork is often installed in buildings that must meet legal compliance guidance such as hospitals, offices, or manufacturing plants.

These systems are designed to withstand high temperatures. This allows the ductwork to continue operating for a defined safety rating during an emergency.

Experts in fire resisting ductwork must ensure that:

• Duct sections are fitted securely
• Joints and access panels are sealed
• Duct runs are suspended safely
• Compartment boundaries remain protected

If fire resisting ductwork is fitted without proper support, gaps may allow smoke or heat to pass between compartments.

A secure fire rated ductwork network helps ensure that fire and smoke remain contained within a defined area for the required period of time.

Fire resisting ductwork is commonly installed within:

• Emergency routes
• Protected staircases
• Service risers
• website Internal service zones

These areas form part of a building’s passive fire protection strategy.

A new fire resisting ductwork installation may be required during the construction of a new building. In some cases, older systems may also need replacement if they no longer meet current fire resistance ratings.

Indoor safety during a fire depends on how effectively smoke movement can be controlled. A correctly installed fire resisting ductwork system helps prevent the movement of heat build up.
